Use the following list of resting pulse rates of 55 people. The mean of these rates is 73.5, and the standard deviation is approximately 13.2.50, 51, 51, 53, 53, 53, 55, 56, 56, 57, 58, 58, 59, 59, 6060, 60, 60, 62, 62, 64, 65, 65, 65, 68, 68, 69, 71, 71, 7272, 73, 75, 76, 77, 78, 78, 81, 81, 81, 82, 82, 82, 82, 8385, 85, 85, 88, 88, 90, 90, 91, 91, 92Determine the pulse rates that are within 1 standard deviation of the mean. What percentage of the total to the nearest 0.1 percent do these rates represent?
Answer:
54.5%
Step-by-step explanation:
Given that :
Mean pulse rate (m) = 73.5
Standard deviation (σ) = 13.2
Pulse rates within 1 standard deviation of the mean :
Mean ± 1(standard deviation )
73.5 - 13.2 < X < 73.5 + 13.2
60.3 < X < 86.7
Pulse rates : 50, 51, 51, 53, 53, 53, 55, 56, 56, 57, 58, 58, 59, 59, 6060, 60, 60, 62, 62, 64, 65, 65, 65, 68, 68, 69, 71, 71, 7272, 73, 75, 76, 77, 78, 78, 81, 81, 81, 82, 82, 82, 82, 8385, 85, 85, 88, 88, 90, 90, 91, 91, 92
Total number pulse rate within 1 standard deviation of the mean = 30
Percentage of the total :
(30 / 55) * 100%
0.5454 * 100%
= 54.54%
= 54.5%

Identify which shapes on the graph are congruent to shape l by preforming these sequences of transformations on shape l:
▪︎ A reflection across the y-axis, followed by a 90ﾟcounterclockwise rotation about the origin, and then are translation 3 units down
▪︎ A 90ﾟcounterclockwise rotation about the origin in their translation 2 units up and units left
▪︎ 180° rotation about the origin and then a translation 1 unit right
Answer:
Your awnsers would be C and B
Step-by-step explanation:
The 2 number shape which is 90ﾟcounterclockwise rotation about the origin and 180° rotation about the origin.
What are transformations?
A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
Given:
After rotation in sequence we will get 2 number shape which is congruent shape.
According to given question we have
A 90ﾟcounterclockwise rotation about the origin : means a right angle about the origin in opposite direction the needle would point to (9=45 mins)the reflection of it would mean the needle is at 3 = 15 min.
180° rotation about the origin : either in the clockwise or counterclockwise direction, each point of the given figure has to be changed from (x, y) to (-x, -y) .
Therefore, the 2 number shape which is 90ﾟcounterclockwise rotation about the origin and 180° rotation about the origin.

A population is normally distributed with a mean of 100 and a standard deviation of 10. For samples of size 25, what is the probability of randomly sampling and finding a sample mean of 99 or more
Answer:
The value is [tex]P( \= X \ge 99) = 0.69146[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 100[/tex]
The standard deviation is [tex]\sigma = 10[/tex]
The sample size is n = 25
The standard deviation of the sampling distribution is
[tex]\sigma_{\= x} = \frac{\sigma}{\sqrt{n} }[/tex]
=> [tex]\sigma_{\= x} = \frac{10}{\sqrt{25} }[/tex]
=> [tex]\sigma_{\= x} = \frac{10}{5 }[/tex]
=> [tex]\sigma_{\= x} = 2[/tex]
Generally the probability of randomly sampling and finding a sample mean of 99 or more is mathematically represented as
[tex]P( \= X \ge 99) = 1 - P(\= X < 99)[/tex]
Here
[tex]P(\= X < 99) = P(\frac{\= X - \mu }{\sigma } < \frac{99 - 100 }{2} )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
=> [tex]P(\= X < 99) = P(Z < -0.5 )[/tex]
From the z table probability of (Z < -0.5 ) is
[tex]P(Z < -0.5 ) = 0.30854[/tex]
Generally
[tex]P( \= X \ge 99) = 1 - 0.30854[/tex]
=> [tex]P( \= X \ge 99) = 0.69146[/tex]

Answer:
b. y = -3x/2 + 2
Step-by-step explanation:
To get 3x + 2y = 4 into slope intercept form:
3x + 2y = 4 (starting equation)
2y = -3x +4 (do the inverse of 3x to get it on the other side)
y = -3x/2 + 2 (divide all of previous equation by 2 to distinguish y)

Step 1: Define
g(x) = -2x + 3
g(3) is x = 3
Step 2: Substitute and Evaluate
g(3) = -2(3) + 3
g(3) = -6 + 3
g(3) = -3
Answer:
g(3) = - 3
Step-by-step explanation:
To evaluate g(3) substitute x = 3 into g(3), that is
g(3) = - 2(3) + 3 = - 6 + 3 = - 3

John worked in a furniture store for a salary of $850 a month, plus a commission of 6% on sales over $20,000. How much did he earn in a month where he sold $36,000 worth of furniture?v
Answer:
He earned in this month $1810
Step-by-step explanation:
∵ John worked in a furniture store for a salary of $850 a month
∴ His fixed salary = $850
∵ He takes a commission of 6% on sales over $20,000
∴ His commission = 6% on sales over $20,000
→ Change it to decimal by divide it by 100
∴ His commission = [tex]\frac{6}{100}[/tex] = 0.06 on sales over $2000
∵ In one month he sold $36,000 worth of furniture
∴ He will take a commission on the value that over $20,000
∵ The amount of selling over $20,000 = 36,000 - 20,000
∴ The amount of selling over $20,000 = $16,000
→ Multiply it by 0.06 to find his commission
∵ His commission = 0.06 × 16,000
∴ His commission = $960
→ Now let us find his total earn
∵ His total earn = his salary + his commission
∴ His total earn = 850 + 960 = 1810
∴ He earned in this month $1810

The price of a new slide in stove is $794. Pedro makes a 10% down payment for a
two-year installment purchase. The monthly payment is $34.25 dollars. What is his
down payment?
Answer:
$79.4
Step-by-step explanation:
Given that :
Price of stove =$794
Down payment = 10% =
Time = 2 years = 24 months
Monthly payment = $34.25
Down payment = 10% of 794
Down payment = 0.1 * $794
Down payment = $79.4
