Answer:

Option A

Step-by-step explanation:

Convert mixed fraction to improper fraction.

$\sf w - 9\dfrac{1}{2}=15\\\\ w - \dfrac{19}{2}=15$

Now isolate 'w'

$\sf w = 15 +\dfrac{19}{2}\\\\= \dfrac{15*2}{1*2}+\dfrac{19}{2}\\\\=\dfrac{30}{2}+\dfrac{19}{2}\\\\=\dfrac{30+19}{2}\\\\=\dfrac{49}{2}\\\\= 24\dfrac{1}{2}$

Answer:

$\huge\boxed{\bf\:w = \frac{49}{2} = 24\frac{1}{2} = 24.5}$

Step-by-step explanation:

$w - 9 \frac { 1 } { 2 } = 15$

Multiply both the sides of the equation by 2.

$2w-\left(9\times 2+1\right)=30 \\2w-\left(18+1\right)=30 \\2w-19=30$

Bring $19$ to the left hand side of the equation.

$2w=30+19 \\2w=49 \\\boxed{\bf\:w = \frac{49}{2} = 24\frac{1}{2} = 24.5}$

What proportion of students are willing to report cheating by other students? A project put this question to an SRS of 180 under

krok68 [10]

Answer:

13.89% of students are willing to report cheating by other students.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 180

Number of students who reported cheating, x = 25

We have to find the proportion of the students are willing to report cheating by other students.

Proportion of students can be calculate as

$p = \dfrac{x}{n} = \dfrac{25}{180} = 0.1389\\\\\p = 0.1389\times 100\5\\p = 13.89\%$

Thus, 13.89% of students are willing to report cheating by other students.

US average math SAT scores follow a normal distribution with a mean of 505 and a standard deviation of 112. A sample of 64 enter

Hitman42 [59]

Answer:

The claim that the scores of UT students are less than the US average is wrong

Step-by-step explanation:

Given : Sample size = 64

Standard deviation = 112

Mean = 505

Average score = 477

To Find : Test the claim that the scores of UT students are less than the US average at the 0.05 level of significance.

Solution:

Sample size = 64

n > 30

So we will use z test

$H_0:\mu \geq 477\\H_a:\mu < 477$

Formula : $z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}$

$z=\frac{505-477}{\frac{112}{\sqrt{64}}}$

$z=2$

Refer the z table for p value

p value = 0.9772

α=0.05

p value > α

So, we accept the null hypothesis

Hence The claim that the scores of UT students are less than the US average is wrong

Write the slope-intercept equation of the line parallel to 5y = 2x + 20 that goes through (-1, 3).

poizon [28]

The first thing I'll do is solve "5y = 2x + 20" for "y=", so that I can find my reference slope:

y = (2/5)x + 4;

So the reference slope from the reference line is m = 2/5;.

Now I need to find two new slopes, and use them with the point they've given me; namely, with the point (-1, 3). They want me to find the line through (4, –1) that is parallel to 5y = 2x + 20; that is, through the given point, they want me to find a line that has the same slope as the reference line.

Since a parallel line has an identical slope, then the parallel line through (-1, 3) will have slope m = 2/5. Now I have a point and a slope! So I'll use the point-slope form to find the line: y - 3 = (2/5)( x + 1);

Finally, y = (2/5)x + 17/5;
