There are 8 students in each row.

Step-by-step explanation:

Given,

Number of students = 56

Number of rows of student formation = 7

To determine the number of students in each row , we will divide the total number of students by number of rows.

Number of students in each row = \frac{56}{7}

Number of students in each row = 8

There are 8 students in each row.

Write in standard form the equation of a line with a slope of -3/5 and a y intercept of -3
Vlada [557]

Answer:

5y+3x=-9

Step-by-step explanation:

Let us start by the general form of the standard equation, Ax+By=C. One way we can solve this problem is by finding the <u>slope-intercept form</u> of this equation, y=mx+b, and converting it into the standard equation. In the slope-intercept form, m represents the slope, b represents the y intercept.

From this problem, we are given both the slope and the y intercept. We know have the equation:

y=-\frac{3}{5}x -3

Great! Now let us rearrange the terms so that the y and x terms are on one side of the equation.

y+\frac{3}{5} x=-3

This seems right, but a standard equation must have coefficient values that are real numbers. So, A and B must be real numbers. We can do this by multiplying the entire equation by 5 and ridding the denominator of the A term.

5y+3x=-9

Illusion [34]

Answer:

Option D. about 170 inches

Step-by-step explanation:

we know that

To find how long is the room in inches multiply the length of the shoe by the number of shoe lengths

so

9.75*17.5=170.6\ in

therefore

the length of the room is about 170 inches

in a given binominal distribution, there are 625 trials, and the probability of success is p=0.29. What is the variance?
KatRina [158]

Answer:

The variance is 129

Step-by-step explanation:

The variance of a binomial distribution is defined as

np(1-p)

where n is the number of trials, and p is the prob of success. So in your case the variance is:

625\cdot 0.29\cdot 0.71 \approx 129

(I am intentionally rounding to nearest integer to make the variance a meaningful value, since the events are discrete and not fractional measurements)
