Answer:

A. 24

Step-by-step explanation:

We know that the formula for find the area of right triangle is (1/2) × (b × h)

Using this formula, we can find the area of this right triangle given the side lengths

the base of this right triangle is 8

the height of this right triangle is 6

(1/2) × (8×6)

(1/2) × (48)

48/2

For which sample size (n) and sample proportion (p) can a normal curve be

Nonamiya [84]

Answer:

Option c.

Step-by-step explanation:

Using the normal curve to approximate a sampling distribution:

For a sample size n and a proportion n, the normal curve can be used if:

$np \geq 10$ and $n(1-p) \geq 10$

Option a:

$np = 35*0.8 = 28 > 10$

$n(1-p) = 35*0.2 = 7 < 10$

So option a cannot be used.

Option b:

$np = 65*0.9 = 58.5 > 10$

$n(1-p) = 65*0.1 = 6.5 < 10$

So option b cannot be used.

Option c:

$np = 65*0.8 = 52 > 10$

$n(1-p) = 65*0.2 = 13 > 10$

So option c can be used, and is the answer

Option d:

$np = 35*0.9 = 31.5 > 10$

$n(1-p) = 35*0.1 = 3.5 < 10$

So option d cannot be used.

The answer is given by option c.

Write an expression for the calculation add 3 and 8 and then multiply by 9

melisa1 [442]

Hey there!

Basically it wants you to add 3 and 8 from each other, what ever the answer to that part, you multiply the result by 9

Here this is what i meant

$3 + 8 = 11 \\ 11 ( 9) = 99$

Or you could do this method too!

$(3 +8) (9) \\ \\ 3 + 8 = 11 \\ 11(9) \\ = 99$

They both give you the result of $99$

So, I am assuming your expression would look like this: $(3 + 8) * 9$

Good luck on your assignment and enjoy your day!

Determine the number of ways a computer can randomly generate one or more such integers from 1 through 30. Two distinct integers

Thepotemich [5.8K]

Answer:

There are 26 possible way to determine two distinct integers whose sum is 27.

Step-by-step explanation:

To find : The number of ways a computer can randomly generate one or more such integers from 1 through 30. Two distinct integers whose sum is 27.

Solution :

We have given the numbers from 1,2,3,4......,29,30.

In order to get two distinct numbers having the sum 27,

There are the possibilities :

1+26=27

2+25=27

3+24=27

......

24+3=27

25+2=27

26+1=27

The maximum number taken is 26.

So, There are 26 possible way to determine two distinct integers whose sum is 27.

A business purchases a computer system for $5,300. The value of the system decreases at a rate of 12% per year. In how many year

N76 [4]

Answer:

Step-by-step explanation:

If a system decreases by 12% it's the same as multiplying it by .12-1 or .88

This means we can create the following equation

computer value=5300(.88)^n

where n is the number of years

We can then plug in the value of the computer and solve for n

2200=5300(.88)^n

Divide by 5300 and get

.415=.88^n

Then put this into log form and get

$\frac{log(.415)}{log.88}$

Evaluate this into your calculator and get n=6.69 which I would probably just round to 7
