Answer:

$6400-(-4700)$

Step-by-step explanation:

Given,

The profit in present month = $ 6,400,

Also, there is a loss of $ 4,700 in the next month,

So, the profit in the next month = -$ 4,700,

Note : Negative sign shows the loss.

Hence, the difference in profit between the two months

= Profit in present month - profit in next month

$=6400-(-4700)$

Which is the required expression.

For the first month we have the following profit or benefit:

$ 6,400

For the second month we have the following loss:

$ 4,700

Therefore, the net benefit is given by:

Net Profit = Profit - Lost

Substituting values we have:

Net profit = 6400 - 4700

Answer:

An expression that you would use to find the difference in profit between the two months is:

Net profit = 6400 - 4700

Sydney read 50 pages in 40 minutes. She reads at a constant rate.How many pages can Sydney read per minute?

7nadin3 [17]

Here we are given how much work is done in a fix time interval

then they ask to find the rate of doing the work .

in such problem we can find the rate of doing a work by using the formula :

amount of work done

--------------------------------------------------- = work done in unit time

Time taken to do that amount of work

In 40 minutes number of pages she reads = 50

In 1 minutes number of pages she would be reading = 50 /40

= 5/4 page

Answer 5/4 page .

The per capita consumption of red meat by people in a country in a recent year was normally distributed, with a mean of 107107

Pachacha [2.7K]

Answer:

mean sample is 9.26

Step-by-step explanation:

Given data

mean = 107 pounds

standard deviation = 39.3 pounds

no of sample (n) = 18

to find out

sample means

solution

according to question we know mean of sample = 107 pounds

so standard error of this sample will be standard deviation / $\sqrt{n}$

now put all value n and standard deviation and we get sample mean i.e.

mean sample = standard deviation / $\sqrt{n}$

mean sample = 39.3 / $\sqrt{18}$

mean sample = 9.26

An isosceles triangle has base angles that each measure 42∘. Which equation can be used to find z, the measure of the third angl

blsea [12.9K]

Answer:

180 - 84 = z

Step-by-step explanation:

all angles in a triangle should add up to 180. If both angles add up to 84 (42 + 42) all theres left to do is to substract 84 from 180 to find z :)

A policyholder has probability 0.7 of having no claims, 0.2 of having exactly one claim, and 0.1 of having exactly two claims. C

Colt1911 [192]

Answer:

0.89.

Step-by-step explanation:

So, we are given the following data or parameters or information which is going to aid in the solution to this question or problem. So, the data or parameters are;

(1). "probability 0.7 of having no claims, 0.2 of having exactly one claim, and 0.1 of having exactly two claims."

(2). " distributed on the interval [0,60] and are independent."

(3). "The insurer covers 100% of each claim."

So, taking (1) above we will have;

(Total probability= 0.7 + 0.2 + 0.1 = 0.1)

A = { (0.7 × 0)^2 + (0.2 × 1)^2 + ( 0.1 × 2)^2 =( 0.4) +( 0.4) = 0.8.

0.8 + total probability = 0.8 + 0.1 = 0.9.

So, from the question, we are to "Calculate the probability that the total beneﬁt paid to the policyholder is 48 or less."

Hence, P< 48/A = P < 48/0.9 = P < 53.33.

Thus, 53.33/60 = 0.89.

Given the information below, match the following items.

Veronika [31]

If two angles are complementary, then it they add up to 90 degrees.
If they add up to 90 degrees, then they are right angles 

So, If two angles are complementary, then they are right angles 

Converse: If two angles add up to 90 degrees, then they are complementary. T 
Inverse: If two angles are not complementary, then they do not add up to 90 degrees T 
Contrapositive: If two angles do not add up to 90 degrees, then they are not complementary angles T 

Hope this helps! ;D
