You are painting your house this summer. If the spot you are trying to reach is 15 feet up the side of the house and you can extend a ladder 6 feet from the base of the house, how long must the ladder be?
Answers
Answer:
16.2 ft
Step-by-step explanation:
use pythagorean theorem
a² + b² = c²
6² + 15² = c²
36 + 225 = c²
261 = c²
Take ther square root of both sides

In timara math class there are, 12 boys and 15 girls which of the following in the ratio to boys and girls in timaras math class?
Answers
Answer:
4:5
Step-by-step explanation:
If there are 12 boys and 15 girls, the ratio of boys to girls will be 12:15.
However, this can be simplified by dividing each number by 3. This can be done since both 12 and 15 are divisible by 3.
12:15
= 4:5
So, the ratio of boys to girls in Timara's class is 4:5
If the mean number of years between asbestos exposure and death is found to be 25 years with a standard deviation of 7 years in a particular county, what is the probability that the mean number of years between asbestos exposure and death will be between 22 and 29 years in a sample of 50 people taken from that community
Answers
Answer:
0.9988 = 99.88% probability that the mean number of years between asbestos exposure and death will be between 22 and 29 years.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
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.
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
The mean number of years between asbestos exposure and death is found to be 25 years with a standard deviation of 7 years in a particular county
This means that [tex]\mu = 25, \sigma = 7[/tex]
Sample of 50:
This means that [tex]n = 50, s = \frac{7}{\sqrt{50}}[/tex]
What is the probability that the mean number of years between asbestos exposure and death will be between 22 and 29 years?
This is the p-value of Z when X = 29 subtracted by the p-value of Z when X = 22.
X = 29
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{29 - 25}{\frac{7}{\sqrt{50}}}[/tex]
[tex]Z = 4.04[/tex]
[tex]Z = 4.04[/tex] has a p-value of 1.
X = 22
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{22 - 25}{\frac{7}{\sqrt{50}}}[/tex]
[tex]Z = -3.03[/tex]
[tex]Z = -3.03[/tex] has a p-value of 0.0012.
1 - 0.0012 = 0.9988
0.9988 = 99.88% probability that the mean number of years between asbestos exposure and death will be between 22 and 29 years.

Answers
Answer:
<A = 45
<B = 110
<C = 25
Step-by-step explanation:
The sum of the angles of a triangle add to 180
x+ x+65 +25 = 180
Combine like terms
2x+90 = 180
Subtract 90
2x+90-90 = 180-90
2x = 90
Divide by 2
2x/2 = 90/2
x = 45
<A = x = 45
<B = x+65 = 45+65 = 110
<C = 25
∠A = 45 °
∠B = 110 °
∠C = 25 °
Step-by-step explanation:
We know that sum of all angles of triangle is 180°.
x + x + 65 ° + 25 ° = 180 °
combine like terms
2 x + 90 ° = 180 °
Subtract 90 ° from each side
2 x + 90 ° - 90 ° = 180 ° - 90 °
2x = 90 °
Divide 90 ° by 2.
x = 90 ° / 2
x = 45 °
Therefore,
∠A= x = 45 °
∠B = x + 65 ° = 45 ° + 65 ° = 110 °
∠C = 25 °

Answer:
110
Step-by-step explanation:
Since the whole thing should equal 360 degrees and the sides are the same length in twos then add 100 + 40 and then do 360 - 140 then divide by two fpr the missing two angles so each are 110 degrees.

Answers
Answer:
[tex]P(Female\ or\ Physics) = 0.38[/tex]
Step-by-step explanation:
Given
[tex]n = 50[/tex] --- total
[tex]Physics =10[/tex]
[tex]Female= 12[/tex]
[tex]Both = 3[/tex]
Required
[tex]P(Female\ or\ Physics)[/tex]
This is calculated as:
[tex]P(Female\ or\ Physics) = P(Female) + P(Physics) - P(Both)[/tex]
So, we have:
[tex]P(Female\ or\ Physics) = \frac{Female+ Physics - Both}{n}[/tex]
[tex]P(Female\ or\ Physics) = \frac{10+ 12- 3}{50}[/tex]
[tex]P(Female\ or\ Physics) = \frac{19}{50}[/tex]
[tex]P(Female\ or\ Physics) = 0.38[/tex]
On each coordinate plane, the parent function f(x) = |x| is represented by a dashed line and a translation is represented by a solid line. Which graph represents the translation g(x) = |x + 2| as a solid line?
On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (2, 0).
On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (0, negative 2).
On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (negative 2, 0).
On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (0, 2).
Answers
Using shifting concepts, we get that the graph that represents the translation g(x) = |x + 2| as a solid line is:
On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (-2, 0).
--------------------------------------------------
Shifting a function f(x) a units to the left is the same as finding f(x + a).--------------------------------------------------
The vertex of the function f(x) = |x| is at the point where x = 0, and thus, f(x) = 0. Thus, the vertex of the dashed line is at (0,0).The vertex of the function g(x) = |x + 2| is at the point where [tex]x + 2 = 0 \rightarrow x = -2[/tex], g(-2) = |-2 + 2| = 0. Thus, the vertex of the solid line is at (-2,0).Thus, the correct option is:
On a coordinate plane, a dashed line absolute value graph has a vertex at (0, 0). A solid line absolute value graph has a vertex at (-2, 0).
At the end of the exercises, there are are the graphs of those two functions, considering the dashed line as the red line and the solid line as the blue line.

Step-by-step explanation:
common denominator for 7z and 3z is 21z
4/7z = 12/21z
2/3z = 14/21z
12/21z + 14/21z = 13
26/21z = 13
cross-multiply to get:
26z = 273
z = 273/26
z = 10.5
Answer:
z = 10.5
Step-by-step explanation:
(4/7)z + (2/3)z = 13
multiply by 21 to eliminate the fractions
12z + 14z = 273
26z = 273

Answers
Answer:
a) 0.7
b) 0.3
c) 0
d) 1
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
(a) Coke
Out of 10, 7. So
[tex]p = \frac{7}{10} = 0.7[/tex]
(b) fanta
3 out of 10. So
[tex]p = \frac{3}{10} = 0.3[/tex]
(c) neither Coke nor fanta
7 Coke, 3 fanta, so all 10 are either coke or fanta. Thus:
[tex]p = \frac{0}{10} = 0[/tex]
(d) either Coke or fanta
All 10. Thus:
[tex]p = \frac{10}{10} = 1[/tex]
