The first statement will be "<em><u>false</u></em>" and the second one is "<em><u>true</u></em>". A further explanation is below.

According to the question,

Number of bacteria after "t" hours,

= 50\times (3)^{\frac{t}{8} }

This will be false.

Now,

After 36 hours,

→ N = 50\times (3)^{\frac{36}{8} }

       = 50\times (3)^{\frac{36}{8} }

       = 50\times (3)^{4.5}

       = 7015

This will be true.

A simple random sample of size n = 20 is obtained from a population with population mean 64 and population standard deviation 17
eimsori [14]

Answer:

Kindly check explanation

0.57691

0.4719

Step-by-step explanation

A.) The distribution of sample means must follow a normal distribution ;

Mean = 64 ; Standard deviation = 17 ;

Standard Error = s/sqrt(n) = 17 / sqrt(20) = 3.8013155

N(64 ~ 17)

Given that:

mean (m) = 64

Sample size (n) = 20

Standard deviation (s) = 17

Find

P(x < 67.3)

Z = (x - m) / s

Zscore = (67.3 - 64) / 17

Zscore = 0.1941176

P(Z < 0.194) = 0.57691 (Z probability calculator)

(c) Find P(x > 65.2).

Zscore = (65.2 - 64) / 17

Zscore = 0.0705882

P(Z > 0.0705) = 0.4719 (Z probability calculator)

7. A photograph negative measures 15 inches by
ella [17]

Answer:

First we need to set a proportion

Currently the negative measures 15 inches by 2 inches. And the longer dimension of the printed version is 4 inches. Therefore:

\frac{2}{y} = \frac{15}{4}

15y = 8

y = 0.5333

Therefore, the dimension of the shorter dimension is 0.5333.

None of the options matches this response, so maybe you forgot to add some information?
