Answer:

Step-by-step explanation:Simplifying

25y = 35

Solving

25y = 35

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Divide each side by '25'.

y = 1.4

Simplifying

y = 1.4

FIRST RIGHT ANSWER GETS BRAINIEST
Diano4ka-milaya [45]

OK, no figure, but from the comment is sounds like the grey area is the big circle minus the small circle.

The diameter of the small circle is 2 so its radius is 1 and its area πr² is π.

The radius of the larger circle is 4, so area 16π

The shaded area is 16π - π

Answer: 15π

At a local school the ratio of boys to girls was 8 to 9 if there were 117 girls how many boys were enrolled in the school?
lilavasa [31]

The number of boys in the schools is 104.

Step-by-step explanation:

Given,

The ratio of boys and girls is 8:9

Number of girls = 117

Let us take,

Number of boys = 8x

Number of girls = 9x

To find the number of boys.

According to the problem,

9x = 117

or, x = \frac{117}{9}

= 13

Hence, the number of boys = 13×8 = 104

On average, 28 percent of 18 to 34 year olds check their social media profiles before getting out of bed in the morning. Suppose
Lostsunrise [7]

Answer:

0.7881 = 78.81% probability that the percent of 18 to 34 year olds who check social media before getting out of bed in the morning is, at most, 32.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

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 pvalue, we get the probability that the value of the measure is greater than X.

In this question:

\mu = 28, \sigma = 5

Find the probability that the percent of 18 to 34 year olds who check social media before getting out of bed in the morning is, at most, 32.

This is the pvalue of Z when X = 32. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{32 - 28}{5}

Z = 0.8

Z = 0.8 has a pvalue of 0.7881

0.7881 = 78.81% probability that the percent of 18 to 34 year olds who check social media before getting out of bed in the morning is, at most, 32.
