PLEASE ANSWER ASAP: Dianna can carry up to 15lbs in her backpack. Her lunch weighs 1 lb, her gym shoes weigh 2 lbs, and her books weigh 1.5 lbs each. Which inequality shows how many books Dianna can carry in her bag if she has her lunch and gym shoes?

Answers

Answer 1

Answer: A

Step-by-step explanation:

she can carry 1.5 pounds of books plus the extra 3 pounds as long as its less than or equal to 15 lbs

Answer 2

The inequality that shows the number of books that Diana can carry in her bag if she has her lunch and gym shoes is 3 + 1.5x ≤ 15.

What inequality represents the number of books that Diana can carry?

The first step is to determine the total weight of the items in her bag:

1 + 2 = 3lbs

The second step is to determine the inequality sign to use:

the inequality sign to be used is the less than or equal to sign - ≤

The equation becomes: weight of items in her bag + (weight of one book x total number of books) ≤ weight the bag can carry

3 + 1.5x ≤ 15

Lillian has 26 counters. Bill has 9 times as many counters as Lillian. How many counters does Bill have?

Answers

Answer:

234 counters

Step-by-step explanation:

If Lillian has 26 counters, and Bill has 9 times as many counters. You can do 26 x 9 which gives you the answer 234. Therefore, Bill has a total number of 234 counters.

The number of the counters Bill will have are 234.

What is the relation?

The connection between the two variables by making them one time to the other is called a relation.

If Lillian has 26 counters, and Bill has 9 times as many counters. You can do 26 x 9 which gives you the answer 234. Therefore, Bill has a total number of 234 counters.

Courtney and Christy both leave the coffee shop at the same time, but in opposite directions. If Christy travels 9 mph faster than Courtney and after 7 hours they are 189 miles apart, how fast is each traveling?

Courtney is traveling ___________ mph.

Christy is traveling _____________ mph.

Answers

Answer:

Courtney is travelling at 9mph

Christy is travelling at 18mph

Step-by-step explanation:

Courtney's speed = x

Christy's speed = y

Christy travels 9 mph faster than Courtney: x+9=y

Distance = speed * time

Courtney's distance after 7 hours = 7x

Christy's distance after 7 hours = 7y

After 7 hours, they're 189 miles apart:

7x+7y=189

x+y=27

x+x+9=27

2x=18

x=9

y=x+9

y=9+9

y=18

An education researcher would like to test whether 2nd graders retain or lose knowledge during the summer when they are presumably not in school. She asks nine 2nd graders to take a comprehension exam at the end of the school year (May), and then asks those same students to come back after the summer (late August) to retake a different but equivalent exam, to see if their level of comprehension has changed. Using the data below, test this hypothesis using an alpha level of .05.
May August
90 100

78 92
50 60

a) What is the appropriate test? Is it a one or two tailed test?
b) State the null hypothesis (in words and using means).
c) State the alternative hypothesis (in words and using means).
d) Find the critical value.
e) Calculate the obtained value by hand. What does your decision mean?

Answers

Answer:

See step by step explanation

Step-by-step explanation:

From the problem statement, we understand that we need to investigate if 2nd graders RETAIN OR LOSE knowledge comparing information concerning two different months, therefore we are going to find out if the information gives us enough evidence of a difference in the two groups

a) The test should be a two tail-test

Sample sizes are small ( n₁ = n₂ = 9 ) which means we have to use t-student test

b and c) Test Hypothesis:

For Null Hypothesis H₀, we establish that the two means are equal, which in this case means that the two samples´ means are equal. And as Hypothesis alternative Hₐ that the H₀ is not true, or that the samples mean are different.

Null Hypothesis H₀ x₁ - x₂ = 0 or x₁ = x₂

Alternative Hypothesis Hₐ x₁ - x₂ ≠ 0 or x₁ ≠ x₂

d) Significance level α = 0,05 then α/2 = 0,025

then t(c) with α/2 = 0,025 and degree of freedom

df = n₁ + n₂ - 2 df = 9 + 9 -2 df = 16

From t s-tudent table we find t(c) = 2,12

e) Calculating:

x₁ and σ₁

x₂ and σ₂

σₓ = [ ( n₁ - 1 )* σ₁² + ( n₂ - 1 )*σ₂² ]/ n₁ + n₂ - 2

Using a calculator:

x₁ = 77,11 σ₁ = 13,86

x₂ = 85,89 σ₂ = 12,74

σₓ = [ ( 8*(13,86)² + 8*( 12,74 )² ] / 16

σₓ = (8* 192,1) + 8* ( 162,31) / 16

σₓ = (1536,8 + 1298,48 ) / 16

σₓ = 177,205

t(s) = ( x₁ - x₂ ) /√ σₓ²/ n₁ + σₓ²/ n₂

t(s) = ( 77,11 - 85,89 )/ (177,205)²/n₁ + (177,205)²/n₂

t(s) = - 8,78 / √3489,07 + 3489,07

t(s) = -8,78 / 83,54

t(s) = - 0,11

Comparing t(s) and t(c)

|t(s)| < |t(c)|

0,11 < 2,12

t(s) is in the acceptance region. We accept H₀

Heavy general purpose trucks are often used in pipeline operations. They are built to hold up when carrying or pulling substantial loads, and yet still be suitable for regular highway use. A new truck with appropriate options is purchased for $47,000. It is estimated to have a useful life of 5 years and a salvage value of $2,900 at that time.

Required:
Develop a table showing the depreciation.

Answers

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Purchase price= $47,000

Salvage value= $2,900

Useful life= 5 years

To calculate the annual depreciation, we need to use the following formula:

Annual depreciation= (original cost - salvage value)/estimated life (years)

Annual depreciation= (47,000 - 2,900) / 5= $8,820

The accumulated depreciation is calculated as follow:

Accumulated depreciation= years of depreciation*annual depreciation

For year 4:

Accumulated depreciation= 8,820*4= $35,280

Finally, the book value is:

Book value= purchase price - accumulated depreciation

Year Annual depreciation Accumulated depreciation Book value

1 8820 8820 38180

2 8820 17640 29360

The number of baby carrots in a bag is normally distributed with a mean of 94 carrots and a standard deviation of 8.2 carrots.

Approximately what percent of the bags of baby carrots have between 90 and 100 carrots?

23.3%

31.2%

45.5%

76.73%

Answers

Answer:

46% is the percent of the bags of baby carrots that have between 90 and 100 carrots

Step-by-step explanation:

The baby carrot is normally distributed.

z = (x - µ)/σ

x is equal to number of baby carrots

µ = mean

σ = standard deviation

Substituting the given values, we get -

90 ≤ x ≤ 100

z = (90 - 94)/8.2 = - 0.49

For z value of -0.49, the probability is 0.31

For x = 100

z = (100 - 94)/8.2 = 0.73

For z value of 0.73, the probability is 0.77

P(90 ≤ x ≤ 100) = 0.77 - 0.31 = 0.46

The percent of the bags of baby carrots having carrots between 90 and 100 carrots is 0.46 × 100 = 46%

Stock in Macy's costs $25.75 per share. Hector buys 200 shares of Macy's
through his broker who charges a commission of $25.75. How much did George
pay in total to purchase the stock?

Answers

Answer: $5175.75

Step-by-step explanation:

The amount that is paid in total to buy the stock will be gotten through the addition of the cost of the shares and the commission paid. This will be:

= (200 × $25.75) + $25.75

= $5150 + $25.75

= $5175.75

Therefore, the total amount that is paid to buy the stock will be $5175.75.
