The following table shows the distribution of people in a tennis tournament, and one
person is to be selected at random.
Find the probability that the selected person is a female.
Express your answer as a decimal, rounded to the nearest hundredth.

Under Age 35
Male 8 Female 18

35 years and older
Male 11 Female18

Answers

Answer 1

Answer:

36/55

Step-by-step explanation:

Total 55 persons, total females 36.

Answer 2

The probability that the selected person is a female from the given table is gotten as; 0.65

What is the Probability?

From the given table we see that;

Males under 35 years = 8

Females under 35 years = 18

Males 35 years and older = 11

Females 35 years and older = 18

Thus;

Total number of people = 8 + 18 + 11 + 18

Total people = 55

Thus, probability that the selected person is a female is;

P(female) = (18 + 18)/55

P(female) = 36/55

P(female) = 0.65

Answers

Answer:

Step-by-step explanation:

a.

(1.36 L)/(10 hr) = (0.136 L)/(hr)

Flow rate = (0.136 L)/(hr) × (1000 mL)/L = (136 mL)/(hr)

136 mL × (27 mg)/(100 mL) = 36.72 mg

Delivery rate = (36.72 mg)/(hr)

b.

(136 mL)/(hr) × (13 gtt)/(mL) = (1868 gtt)/(hr)

How many different simple random samples of size 4 from a population size 46

Answers

Answer:   163,185

This is one single number. The number is slightly larger than 163 thousand.

====================================================

Explanation:

Consider four slots labeled A,B,C,D

We have....

46 choices for slot A45 choices for slot B44 choices for slot C43 choices for slot D

There's a countdown going on (46,45,44,43) when filling up the slots. This countdown is because we cannot reselect any specific person for multiple slots at the same time.

If order mattered, then we'd have 46*45*44*43 = 3,916,440 permutations possible.

However, order doesn't matter. For any group of 4 people, there are 4! = 4*3*2*1 = 24 ways to arrange them. So we must divide the previous result over 24 to get (3,916,440)/24 = 163,185

This means there are 163,185 different combinations and this is the number of possible samples of size 4 from a population of 46 people. The order of any sample doesn't matter.

  (b)  It means that the results that Tessa obtained are too unusual to be explained by chance alone

Step-by-step explanation:

The test for statistical significance is a comparison of the result to the probability that it occurred by chance. The probability of a chance occurrence is usually set at 1% or 5%. The lower the percentage, the less likely a chance occurrence is, and the more difficult showing statistical significance becomes.

Answers

Answer:

48

Step-by-step explanation:

About 40 millions of aluminum cans can be recycled each month in the US. A quarter of these aluminum cans are used to make one aluminum boat. How many aluminum boats can be made in one year in the US?

Given that:

Approximate Number of cans that can be recycled per month in the US = 40 million

Fraction of recycled cans that can be used to make an aluminum boat = 1/4

The number of aluminum boats that can be made in the US in one year :

If about 40 million cans are recycle per month :

The number of boat that can be made from each monthly recycled aluminum cans will be :

Number of monthly recycled can needed to make one boat:

1/4 * 40 million = 10 million cans

Hence, 40,000,000 / 10,000,000 = 4

4 aluminum boats can be made in one month :

Number of months in a year = 12

Number of aluminum boats that can be made in a year :

4 per month * 12 = 48 aluminum boats

Answer:

DGF = 106

Step-by-step explanation:

Bisects means to divide in half, with two equal parts

DGF = DGE + EGF

DGE = EGF

DGF = DGE + DGE

DGF = 53+53

DGF = 106

GE bisects ∠DGF, so it divides ∠DGF into 2 equal parts.

So, m∠EGF = m∠DGE

=> m∠EGF = 53°

m∠DGF = m∠EGF + m∠DGE

=> m∠DGF = 53° + 53°

Answers

Answer:

The answer is below

Step-by-step explanation:

The bar chart to the question is attached below.

The distance traveled by Paolo = 210 m, The distance traveled by Lucas = 150 m, The distance traveled by Jashua = 175 m, The distance traveled by Topher = 190 m

1) The farther distance walk by Paolo = The distance traveled by Paolo - The distance traveled by Topher = 210 m - 190 m = 20 m

2) The farther distance walk by Jasha = The distance traveled by Jashua - The distance traveled by Lucas = 175 m - 150 m = 25 m

3) The farther distance walk by Topher = The distance traveled by Topher - The distance traveled by Lucas = 190 m - 150 m = 40 m

4) Combined distance of Paolo's and Lucas = 210 m + 150 m = 360 m

Combined distance of Jashua and Topher = 175 m + 190 m = 365 m

Therefore the Combined distance of Jashua and Topher is more

5) Average distance = (210 + 150 + 175 + 190)/4 = 181.25 m

Another name for the average rate of change is slope.

Step-by-step explanation:

The average rate of change of the cost of a pack ([tex]r[/tex]), in monetary units per year, is equal to the change in the average cost of a pack ([tex]\Delta c[/tex]), in monetary units, divided by the change in time ([tex]\Delta t[/tex]), in years. Then, the average rate of change is:

[tex]r = \frac{\$\,5.31-\$\,0.88}{2000-1980}[/tex]

The diameters of bolts produced in a machine shop are normally distributed with a mean of 5.7 millimeters and a standard deviation of 0.08 millimeters. Find the two diameters that separate the top 3% and the bottom 3%. These diameters could serve as limits used to identify which bolts should be rejected. Round your answer to the nearest hundredth, if necessary.

Answers

Answer:

The diameter that separates the top 3% is of 5.85 millimeters, and the one which separates the bottom 3% is of 5.55 millimeters.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 5.7 millimeters and a standard deviation of 0.08 millimeters.

This means that [tex]\mu = 5.7, \sigma = 0.08[/tex]

Top 3%

The 100 - 3 = 97th percentile, which is X when Z has a p-value of 0.97, so X when Z = 1.88.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.88 = \frac{X - 5.7}{0.08}[/tex]

[tex]X - 5.7 = 1.88*0.08[/tex]

[tex]X = 5.85[/tex]

Bottom 3%

The 3rd percentile, which is X when Z has a p-value of 0.03, so X when Z = -1.88.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-1.88 = \frac{X - 5.7}{0.08}[/tex]

[tex]X - 5.7 = -1.88*0.08[/tex]

[tex]X = 5.55[/tex]

The diameter that separates the top 3% is of 5.85 millimeters, and the one which separates the bottom 3% is of 5.55 millimeters.

Answers

Answer:

[tex]\mu = 15.6[/tex]

Step-by-step explanation:

Given

[tex]p =13\%[/tex]

[tex]n = 120[/tex]

Solving (a): The mean

This is calculated as:

[tex]\mu = np[/tex]

So, we have:

[tex]\mu = 13\% * 120[/tex]

[tex]\mu = 15.6[/tex]

Solving (b): The standard deviation

This is calculated as:

[tex]\sigma = \sqrt{\mu * (1 - p)[/tex]

So, we have:

[tex]\sigma = \sqrt{15.6 * (1 - 13\%)[/tex]

[tex]\sigma = \sqrt{15.6 * 0.87[/tex]

[tex]\sigma =\sqrt{ 13.572[/tex]

(excerpt) I achieved the unofficial "smart kid" designation in elementary school, and it was not until years later that I met someone who threatened to depose me from my reign.His name was George, after our nation's first president, and he had been the smartest kid in school during his early academic career as well; but George grew up on the other side of town, so we had really never crossed paths. We were introduced in our biology class, seated at opposite ends of the first row of desks. When our teacher began asking basic questions to test our science knowledge, George and I had not even noticed each other's existence.But when Mr. Hartley inquired about the aardvark's natural habitat, both of us shot a hand into the air."Africa!" exploded the dual shout, followed by snickering from the rest of the class. I peeked in the direction of the other voice to see George gazing directly ahead, as though he was oblivious to anyone else. Surely, he perceived the awkwardness of this circumstance, and had the abrupt comprehension that there was another "smart kid" in the school! But no acknowledgment crossed his face, and I stared back at my own desk as class continued.When the bell rang and students began jostling out the door, I hung back, thinking that I should at least introduce myself to George. He had waited for everyone else to push out of the classroom as well, and I extended my hand toward him with a smile. "I just wanted to let you know that I plan to outdo you in every class we have together this semester, and every semester until graduation," he said.Without glancing in my direction, George dashed out the door and down the hall toward his locker. I was left in shock at his words, at the audacity of his confidence and conceit. After standing immobile for a few moments, I ducked out the side door of the classroom into the late summer sunshine to comprehend what had just transpired. Ultimately, I came to the apparent explanation to his immature attack: George perceived me as a threat.When the regional science fair was announced, I knew George had already begun working on his entry, as I had. On the day of presentations, as professors from the local university strolled among poster board displays and homemade volcanoes, I had a clear view of George's project. When he detected my surveillance, George began sauntering toward me and I planted my feet firmly, steeling myself for the verbal assault."Is this your first science fair?" he inquired, observing my display critically. "I want to make you aware that I'm going to""I know, I know. You're going to beat me at everything." George smirked, self-satisfied and headed back toward his own project. Anger surged through me as I thought of his haughty conduct, his readiness to belittle me at every opportunity. But it was imperative that George not divert me, and I regained my composure as I spied a science fair judge in my peripheral vision.By November, George was plainly exhausted by his one-sided antagonism, and I scarcely saw him after Thanksgiving. When report cards were distributed before Christmas, he never approached me to compare grades, and I knew that he had relinquished the battle.1Select the correct answer.Which statement best expresses how the underlined section creates an effect in the plot?A.
