The answer is 2.25

You could multiply 0.5 by 72, then by 36, then by 18, and so on, until you found the 6th term.

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)

Plugging these into the formula, we get:

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

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

Note: $P(z\geq a)=1-P(z\leq a)$

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.

Nicholas started a canned-food drive at school. The equation representing this is y = 235x + 15, where x is the number of days,

Olenka [21]

Answer:

well, 11 days

Step-by-step explanation:

if you were to put take out the y and put 2600 in the y place (2600=235x+15)

you solve that, and will come to 11 days

further explaining:

2600-15 = 2585

2585 / 235 = 11

( I'm not sure if this is right, the question is worded weird and almost doesn't make sense)

but I think it is looking for substitution

Hope this helps!
