A) When x is made negative, it gets reflected over the x-axis.

B) When x and y is made negative, it gets reflected over the x-axis and y-axis.

C) Every y-value from the equation would be multiplied by 2, thus changing the shape of the graph. The slope is divided by 2.

D) Every x-value from the equation would be multiplied by 2/3, thus changing the shape of the graph. The slope is divided by 2/3.

E) x-values are divided by 2 and y-values are multiplied by 1.5.

So if talking about points on a graph then
a. x is made negative or opposite of what it is
basically, the x point would go x units from the zero line in the other way it is currently ie. reflected across the x axis

b. both x and y are positive,
basically the figure would be reflected across the x axis then reflected across the y axis (or y axis then x, doesn't matter)

c. y times 2
y is 2 times as high (gets bigger)

d. 2/3 times x
x is 2/3 as much as it was before (gets smaller)

e. 1/2 x and 1.5 y
x get's half smaller and y gets 1.5 bigger (x gets smaller, y gets bigger)

According to scientific research, the probability that a person between the ages of 20 and 25 having high blood pressure, is onl

boyakko [2]

Answer:

<h2>The probability is ${\frac{83}{100} }^9 \times \frac{17}{100}$ + ${\frac{83}{100} }^8 \times {\frac{17}{100} }^2$ + ${\frac{83}{100} }^{10}$ .</h2>

Step-by-step explanation:

The probability of having high blood pressure is 17%.

We need to find the probability of 2 or fewer have high blood pressure.

Possibility 1: No one have high blood pressure.

The probability is ${\frac{100 -17}{100} }^{10} = {\frac{83}{100} }^{10}$ .

Possibility 2: Only one have high blood pressure.

The probability is ${\frac{83}{100} }^9 \times \frac{17}{100}$ .

Possibility 3: 2 among the 10 have the high blood pressure.

${\frac{83}{100} }^8 \times {\frac{17}{100} }^2$ .

Any of the possibilities can happen.

Hence, the required probability is ${\frac{83}{100} }^9 \times \frac{17}{100}$ + ${\frac{83}{100} }^8 \times {\frac{17}{100} }^2$ + ${\frac{83}{100} }^{10}$ .

Ksenya-84 [330]

Both the sample can be used to make inferences about the population.

The correct option is D.

Given

Jason and Yolanda both drew a simple random sample from a non-normally distributed population of 25,000.

Jason’s sample consisted of 0.24% of the population, while Yolanda’s sample consisted of 0.32% of the population.

<h3>Percentage;</h3>

A percentage is a number or ratio that can be expressed as a fraction of 100.

According to the question

Total number of population = 25000

Percent of a sample of Jason = 0.24%

Percent of the sample of Yolanda's = 0.32%

So, the number of the population according to Jason's sample is given by;

$=\dfrac{0.24}{100}\times 25000\\\\=0.24 \times 250\\\\=60$

The number of the population according to Yolanda's sample is given by;

$=\dfrac{0.32}{100}\times 25000\\\\=0.32 \times 250\\\\=80$

Hence, Both the sample can be used to make inferences about the population
