ruslelena [56]

Answer: provided in the explanation segment

Step-by-step explanation:

(a). from the question, we can see that since that б is known, we can use standard normal, z.

we are asked to find an 80% confidence interval for the average weights of Allen's hummingbirds in the study region. What is the margin of error?

⇒ 80% confidence interval for the average weight of Allen's hummingbirds is given thus;

x ± z * б / √m

which is

3.15 ± 1.28 * 0.32/√10

= 3.15 ± 0.1295 = 3.0205 or 3.2795

(b). normal distribution of weight (c) б is known

(c). option (a) and (e) are correct

(d).  from the question, let sample size be given as S

this gives';

1.28 * 0.32/√S = 0.15

√S = (1.28 * 0.32) / 0.15 = 2.73

S = 7.4529

cheers i hope this helps

Going down a water slide is a real-life example of a translation.<br><br> True<br><br> False
LiRa [457]
True i think because going down a water-slide is really a translation, because you are changing from one place to another. SO i believe it would be true. Sorry if this isn't correct.

Answer:

The smallest model - bottom right - in the question diagram represents \sqrt[3]{64}=4.

Step-by-step explanation:

Considering the radical expression

\sqrt[3]{64}

Lets simply this radical expression first

As

\sqrt[3]{64}

\mathrm{Factor\:the\:number:\:}\:64=4^3

=\sqrt[3]{4^3}

\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^n}=a,\:\quad \:a\ge 0

\sqrt[3]{4^3}=4

      =4

Therefore, \sqrt[3]{64}=4

Now, as we can determine that \sqrt[3]{64}=4. So, the smallest model in the question diagram represents \sqrt[3]{64}=4 as each face of the cube of the smallest model in the diagram - bottom right - has 4 squares.

Therefore, the smallest model - bottom right - in the question diagram represents \sqrt[3]{64}=4.

Keywords: square cube root, radical expression
