The sum of 2 consecutive numbers is 43. What are the numbers

Which of these choices show a pair of equivalent expressions? CHECK ALL THAT APPLY

aleksklad [387]

Answer:

Option C & D

Step-by-step explanation:

<u>FACTS TO KNOW BEFORE SOLVING</u> :-

Lets say there's an expression $x^{\frac{a}{b} }$ .

It can be also written it as → $(\sqrt[b]{x} )^{a}$ and vice-versa.

Lets come to the question.

In option A , $7^{\frac{5}{7} }$ can be also written as $(\sqrt[7]{7} )^{5}$ . But it doesn't match with the other expression given. Hence they are not equivalent expressions.

In option B , $6^{\frac{2}{7} }$ can be also written as $(\sqrt[7]{6} )^{2}$ . But it doesn't match with the other expression given. Hence they are not equivalent expressions.

In option C , $5^{\frac{3}{2} }$ can be also written as $(\sqrt{5} )^{3}$ . Hence they are equivalent expressions.

In option D , $(\sqrt[4]{81} )^{5}$ can be also written as $81^{\frac{5}{4} }$ . Hence they are equivalent expressions

Thus , Option C & D are correct.

What are the answers to 1 5 3 and 6 really aprreciate it!

Gelneren [198K]

1. y=3/4x-3 (just from a triangle from one point on the line to anotheron the line where both end at a point.
2. y=5/1x which is also y=5x (basically subtract y^2-y^1/ x^2-x^1 ex. -2--7/5-4
3.y=2/3x-1/2
4.-3/-1 which is two negatives dividing which makes it positive. y=3x
5.cant see
6. Find slope first. y=3x then use point (1,1) move one left and 3 down. and the y intercept would be -2

I NEED HELP GIVING BRAINLIEST

MAXImum [283]

Answer:

For 1) you must do that yourself from least to greatest.

2) most snow was 3 and 3/4

3) least snow was 1 and 2/4

4) it snowed 3 and 1/4 3 days long.

5) it could have been 4 and 2/4 with another 1 and 2/4 since that makes three or maybe just 4 with 1 since that also makes three there are a lot of possibilities considering it only has to be subtracted and equal three.

Step-by-step explanation:

Hope this helped.

A brainliest is always appreciated.

The hypothesis is given as

H0: μd< 0

H1: μd > 0

<h3>How to solve for the hypothesis.</h3>

The null hypothesis is given as

H0: μd< 0

<h3>The alternative hypothesis is given as </h3>

H1: μd > 0

SWe have to find the value of s

we would use this formula s = sqrt [ (Σ(di - d)^2 / (n - 1) ]

This gives us 3.454

Next we have to determine the standard error

s / √(n)

3.454/2.8284

= 1.22

Degree of freedom = 8 - 1

= 7

t = (x1 - x2) - D / S.E

= 1.025

Find t critical at 0.10

= 1.895

P-value = 0.1697

d. Given that p value is greater thatn 0.1 we fail to reject the null hypothesis.
