4 0

Line them up
3x3= 9, 3x2= 6, 3x5= 15

Add a 0 under the 9, 7x3= 21, leave the 1 and carry the 2, 7x2= 14+2= 16 leave the 6 and carry the 1, 7x5= 35+1= 36

9+0= 9, 6+1= 7, 5+6= 11 leave 1 carry 1, 1+6= 7+1= 8, 0+3= 3

523
x 73
———

Answer: -12 but could be wrong

Step-by-step explanation:

I don't know that format but I'm going to take a guess.

x^2 +2x - 8 -(2x+8) then plug in x=2

x^2 + 2x - 8 - 2x - 8

x^2 -16

= 2^2 - 16 = -12

The heights of the trees in a forest are normally distributed, with a mean of 25 meters and a standard deviation of 6 meters. Wh

Alla [95]

Answer:

2.3%

Step-by-step explanation:

The formula to convert x into z distribution is

$z=\frac{x-\mu}{\sigma}$

Where z is the test statistic

x is what we are looking for (in this case 37)

$\mu$ is the mean (in this case, it is 25)

$\sigma$ is the standard deviation (we have 6)

<em>Plugging these into the formula, we get:</em>

$z=\frac{x-\mu}{\sigma}\\z=\frac{37-25}{6}\\z=2$

Thus we can say we want $P(z\geq 2)$

<u>Note: </u> $P(z\geq a)=1-P(z\leq a)$

The table given is for any z where $P(z\leq a)$

Thus, now we have:

$P(z\geq 2)\\=1-P(z\leq 2)\\=1-0.9772\\=0.0228\\$

0.0228 into percentage is 0.0228 * 100 = 2.28%

Rounded, we get 2.3%

Third answer choice is right.

I will give Brainliest its maths and I need help on a b and c

JulsSmile [24]

Answer:

${5}^{3} \times {5}^{x} = {5}^{7} \\ 3 + x = 7 \\ x = 4$

$( {q}^{2} )^{y} = {q}^{6} \\ 2y = 6 \\ y = 3$

${1000}^{m} \div {100}^{n} = {10}^{z} \\ \frac{1000 ^{m} }{ {100}^{n} } = {10}^{z} \\ \\ {10}^{m - n} = {10}^{z}$

Can I have the brainliest please?
