18m+5=6m+ 17 m=6 Pls help fast

1 answer:

8 0

Answer: 113=53 (This is a false equation, meaning that both sides are not equal to each other)

Explanation: I’m not sure what your answer choices are but to get that answer I first rewrote the equation with the variable “m” replaced with 6 since m=6. Therefore it should be 18(6)+5=6(6)+17. Then I multiplied 18 by 6 to get 108, to then add 5 to get 113. Following that, i then multiplied 6 by 6 to get 36 then added 17 to get 53. The equation would then look like 113=53 when solved.

The correct answer is B.

The reason they are testing this new sports drink is to see if it will work better, worse, or "differently" as they are putting it! The other answers do not have anything to do with the experiment.

Hope this helps! Would love brainliest trying to get to virtuoso thanks!

A grading scale is set up for 1000 students' test scores. It assumes the

astra-53 [7]

Answer:

464 students will score between 48 and 75. Using the z-distribution, we measure how many standard deviations each score is from the mean, then find the p-value associated with each score to find the proportion, and from the proportion, we find how many out of 1000.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

It assumes the scores are normally distributed with a mean score of 75 and a standard deviation of 15.

This means that $\mu = 75, \sigma = 15$

How many students will score between 48 and 75?

First we find the proportion, which is the pvalue of Z when X = 75 subtracted by the pvalue of Z when X = 48. So

X = 75

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

$Z = \frac{75 - 75}{15}$

$Z = 0$

$Z = 0$ has a p-value of 0.5

X = 48

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

$Z = \frac{48 - 75}{15}$

$Z = -1.8$

$Z = -1.8$ has a p-value of 0.0359

1 - 0.0359 = 0.4641

Out of 1000:

0.4641*1000 = 464

Help pls!!!!! Brainliest goes to first right answer

zepelin [54]

Answer:

96 inch²

Step-by-step explanation:

there are 2 shapes,

1. a square

2. a triangle

lets find the area of the square first,

AREA = SIDE × SIDE

= 8 × 8

= 64 inch²

now, area of triangle ,

$area \: = \frac{1}{2} \times base \: \times height \:$

$= \frac{1}{2} \times 8 \times 8 \\ = \frac{1}{2} \times 64 \\ = 32 \: {inch}^{2}$

so, total area is :

area of square + area of triangle

= 64 + 32

= 96 inch²

For question 3, use the Pythagorean Theorem.

Juliette [100K]

Step-by-step explanation:

can't really use the Pythagorean because you don't know this is a right triangle.

use the fact that they are similar

3/6 = x/12 where x is FE

cross multiply

6x = 36 therefore FE = 6

then 6/12 = y/9 where y is FD

cross multiply

12y = 54 = 54/12 therefore FD = 4.5
