Answer:

The blank or n is -24

Step-by-step explanation:

You are trying to fill in the blanks of -4+n=-28

First, you would need to solve for n which is the blank/number you would want to look for.

Start by adding 4 on both sides

The equation should look like this: n=-28+4

Now, solve -28+4

The answer should be -24 because negative to positive is a subtraction problem, carry the bigger sign meaning -28 is bigger than +4 so you should utilize the negative symbol (in simple terms: your answer has to be negative).

So n= -24

Equation: -4+(-24)=(-28)

It is equivalent and works 100%

Delvig [45]

Answer:

b=44

b=44 - 9

b=44 + 5

x+x+x = 44

x + (x-9) + (x+5) = 44

3x - 4 = 44

+4

3x =48

÷3

x=16

So, first photo contains 16 birds.

x=16

(x-9) - - > 16-9 = 7

(x+5) - - >16+5=21

16 + 7 + 21 =44

Answer is 16 birds in first photo

Hope this helps!

A sample has a sample proportion of 0.3. which sample size will produce the
jasenka [17]

The sample size of 36 will produce the widest 95% confidence interval when estimating the population parameter option (b) is correct.

<h3>What are population and sample?</h3>

It is described as a collection of data with the same entity that is linked to a problem. The sample is a subset of the population, yet it is still a part of it.

We have:

A sample has a sample proportion of 0.3.

Level of confidence = 95%

At the same confidence level, the larger the sample size, the narrower the confidence interval.

As we have a 95% confidence interval the sample size should be lower.

The sample size from the option = 36 (lower value)

Thus, the sample size of 36 will produce the widest 95% confidence interval when estimating the population parameter option (b) is correct.
