Will make brainiest if answered correctly write the value of the expression 2^3/2^3

Find the missing side or angle. Round to the nearest tenth.

BartSMP [9]

Answer:

$b = 2.7$

Step-by-step explanation:

Given:

< C = 53°

< B = 80°

a = 2

Required:

Find b

Solution:

The question given suggests we are given measures for a ∆.

To find side b, which corresponds to angle B, first, we'd find angle A, which corresponds to side a, then apply the Law of sines to find side b.

=> A = 180 - (53 + 80) = 47°

Law of Sines: $\frac{a}{sin(A} = \frac{b}{sin(B}$

Plug in the values into the formula

$\frac{2}{sin(47} = \frac{b}{sin(80}$

Cross multiply

$2*sin(80) = b*sin(47)$

Divide both sides by sin(47) to make b the subject of formula

$\frac{2*sin(80)}{sin(47} = b$

$2.69 = b$

$b = 2.7$ (nearest tenth)

One analog clock loses 3 minutes every 2 hours and another analog clock gains 3 minutes every 4 hours. At noon, the owner sets t

Nadusha1986 [10]

Answer:

12 noon

Step-by-step explanation:

Clock 1 loses 3 minutes every 2 hours. Now, 2 hours = 120 minutes.

This means, it has speed of 120 - 3 = 117 minutes for every 2 hours.

Thus, in 1 hours, it's speed = 117/2 = 58.5 min/hr

Clock 2 gains 3 minutes every 4 hours

Which means in an hour, it gains ; 4/3 minutes

Thus, it's speed an hour is; 60 + 4/3 = 61.333 min/hr

Now, When he returns home in less than two weeks, the clocks show the same time.

let's say the number of hours he was away is x. For the 2 clocks to show the same time, it means they have to show it by 12 noon at another day since it was at noon that he set the correct times before leaving.

Thus, they will both be showing 12 noon.

The standard deviation of a normally distributed population is 24.0. A sample of size 4 is randomly selected. The standard error

Vlad1618 [11]

The standard error of the mean is 12.

The standard error of the mean points to the standard deviation of the distribution of a sample mean obtained from a population.

The standard error S.E of the mean can be calculated by using the formula:

$\mathbf{S.E = \dfrac{\sigma }{\sqrt{n}}}$

where;

standard deviation $\sigma$ = 24
sample size n = 4

$\mathbf{S.E = \dfrac{24 }{\sqrt{4}}}$

$\mathbf{S.E = \dfrac{24 }{2}}$

S.E = 12
