<h3>sry if im wrong...</h3>

Step-by-step explanation:

2(3 + 4x) = 8x + 6

rerange terms-

2(3+4x)= 8x+6

2(4x+3)= 8x+6

distribute-

2(4x+3)= 8x+6

8x+6=8x+6

subtract 6 from both sides of the equation-

8x=8x

subtract 8x from both sides of the equation-

8x=8x

8x-8x=8x-8x

simplify-

0=0

result-

0=0

the input is an identity: it is true for all values

Answer:

Infinite number of solutions

Step-by-step explanation:

$2(3 + 4x) = 8x + 6\\6 + 8x = 8x+6\\8x-8x=6-6\\0=0$

For any value of x, both equations are equal to each other because both sides are identical

Suppose that scores on the mathematics part of a test for eighth-grade students follow a Normal distribution with standard devia

riadik2000 [5.3K]

Answer:

We need an SRS of scores of at least 153.

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1-0.9}{2} = 0.05$

Now, we have to find z in the Ztable as such z has a pvalue of $1-\alpha$ .

So it is z with a pvalue of $1-0.05 = 0.95$ , so $z = 1.645$

Now, find M as such

$M = z*\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

How large an SRS of scores must you choose?

This is at least n, in which n is found when $M = 20, \sigma = 150$ . So

$M = z*\frac{\sigma}{\sqrt{n}}$

$20 = 1.645*\frac{150}{\sqrt{n}}$

$20\sqrt{n} = 1.645*150$

$\sqrt{n} = \frac{1.645*150}{20}$

$\sqrt{n} = 12.3375$

$(\sqrt{n})^{2} = (12.3375)^{2}$

$n = 152.2$

Rounding to the next whole number, 153

We need an SRS of scores of at least 153.

in a recent year, the price of a gallon of heating oil in new england rose 3¢, dropped 4¢, and then rose 7¢. by how much did the

11111nata11111 [884]

the price of oil has increased by $0.06 during the period

you would do 3-4=-1 and then -1+7= 6

so you would be left with a gain of $0.06

hope this helps! good luck!
