Answer:

[tex]20.5\%[/tex]

Step-by-step explanation:

Let's write out a case for two specific questions being correct and the rest being incorrect:

[tex]\frac{1}{5}\cdot \frac{1}{5}\cdot \frac{4}{5}\cdot \frac{4}{5}\cdot \frac{4}{5}[/tex],

The [tex]\frac{1}{5}[/tex] represents the chances of getting the question correct, as there are 5 answers and 1 correct answer choice.

The [tex]\frac{4}{5}[/tex] represents the chances of getting the question incorrect, as there are 5 answers and 4 incorrect answer choices.

The equation above does show the student getting two answers correct and three answers incorrect, but it only shows one possible case of doing so.

We can choose any two of the five questions to be the ones the student gets correct. Therefore, we need to multiply this equation by the number ways we can choose 2 from 5 (order doesn't matter): [tex]\binom{5}{2}=10[/tex].

Therefore, the probability the student gets two questions correct is:

[tex]\frac{1}{5}\cdot \frac{1}{5}\cdot \frac{4}{5}\cdot \frac{4}{5}\cdot \frac{4}{5}\cdot \binom{5}{2}=\frac{1}{5}\cdot \frac{1}{5}\cdot \frac{4}{5}\cdot \frac{4}{5}\cdot \frac{4}{5}\cdot 10=0.2048\approx \boxed{20.5\%}[/tex]

Answer:

2.5x=26-1

x=25/2.5

x=10

Step-by-step explanation:

Answer:

I assume you're solving for x, so the answer is 10

Step-by-step explanation:

First you isolate the x, so you need to subtract one from both sides, which results in the equation 2.5x = 25, and then you divide 25 by 2.5, which gives you x = 10

Answer:

4725 pesos

Step-by-step explanation:

The price p of an aluminum tube is jointly proportional to its radius r and the length l.

For joint variation, we have the expression:

p ∝rl

Hence

p = krl

Step 1

Solving for k

if a 12-foot pipe with 5-inch radius costs 5250 pesos,

5250 = k × 12 × 5

5250 = 60k

k = 5250/60

k = 87.5

Step 2

how much will be the cost of a 9-foot pipe with a 6-inch radius

We make use of the expression:

p = krl

p = 87.5 × 9 × 6

p = 4725 pesos

Therefore, the cost is = 4725 pesos

Answer: j=8

Step-by-step explanation: first, add 5 to both sides. You now have 9j = 72. Then divide each side by 9. You now have j=8

Step-by-step explanation:

4 1/4-5/6

Get a common denominator of 12

4 1/4 *3/3 - 5/6 *2/2

4 3/12 - 10/12

Borrow from the 4

3 + 12/12 + 3/12 - 10 /12

3 15/12 - 10/12

3 5/12

6/12

- 1/12

= 5/12

6 - 3 = 3

= 3 5/12

Answer:

y = 4/3x - 3

Step-by-step explanation:

Use this formula to find the slope first.

(y2 - y1) / (x2 - x1)

(x2, y2) --> (-3, -7)

(x1, y1) ---> (3, 1)

Now plug in:

(-7 - 1) / (-3 - 3)  =  -8 / -6  =  4/3

Now find the y intercept by plugging any points to y= 4/3x + b

I will use (3, 1).

1 = 4/3(3) + b  

1 = 4 + b  (subtract 4 on both sides)

-3 = b

So the formula is

y = 4/3x - 3

Answer:let the initial number of shells that dev has be A, and initial number of shells that zoe has be B. let the number of shells that zoe gives to dev be x. after giiving x shells zoe is left with 3 times the number of shell as that of dev. therefore number of shells with zoe = 3×number of shells with dev.

in a 45-45-90 triangle, the hypotenuse is [tex]\sqrt{2}[/tex] multiplied by the side across from the 45° angle

Answer:

56

Step-by-step explanation:

25

We'll start by getting rid of the negatives, because a negative times a negative equals a positive.

Multiply the whole number by the numerator first, then divide by the denominator.

35 x 5 = 175

175/7 = 25

Answer:

I believe it is A I may be wrong

It is similar to Triangle ABC and has coordinate A'(8, -12), B'(4, -16), and C' (-20, 8).

Since its getting dilated by 2 it will be getting bigger

Answer:

I= $45

Step-by-step explanation:

Giving the following information:

Edna has $900 in a savings account that earns 5% interest per year.

To calculate the interest earned, we need to use the simple interest formula:

I= P*r*t

P= principal= $900

r= interest = 0.05

t= time= 1

I= 900*0.05*1

I= $45

Answer:

B is the answer

Step-by-step explanation:

Answer:

The equation would be y=mx+b so plugging in the slope which is, 11, so y=11x+b WE DO NOT KNOW THE Y INTERCEPT

Answer:

Step-by-step explanation:

Hi, Emily. The average rate of change can be calculated by adding all the profits together and dividing by the different profits (4 profits all together A to D) so 10,600+21,600+-21,600+-10,600= 0

0/4= 0

So we can best describe this as 0 or nothing at all as it hasnt changed from year 2 to 4.

Answer:

a. 1/3 = 3 b. 4/5 = 5/4 c. 7 = 1/7

Step-by-step explanation:

Reciprocal means switching the numerator to the denominator and the denominator to the numerator. Whenever you have a whole number, there is an imaginary 1 as the denominator that is why the reciprocal of 7 is 1/7.

Answer:

37.68

Step-by-step explanation:

D=12

PI=3.14

C=(D)(PI)

C=(12)(3.14)

C=37.68

Answer:

Step-by-step explanation:

angle 1=130 degree(being alternate angles)

angle 2=50 degree

angle 2 +130=180 degree(being co interior angle)

angle 2=180-130

angle 2=50 degree

Answer:

m<1 = 50

m<2 = 130

Step-by-step explanation:

From the picture, you can inference that m<1 looks like 130 degrees, and m<2 does not. You can tell because m<1 looks like a wide-angle, while m<2 looks like a closed-angle. So, m<1 is 130 degrees.

To find m<2 subtract 180 by 130 because 180 is the measure of a straight angle.

180 - 130 = 50

So m<1 = 50

The area of square four is a² + b² + 2ab

The area of a square = l²

The Area so the two square = a² + b²

Area of the  triangles = 4(0.5ab) = 2ab

Add the area together

Area of the square four = area of square + area of 4 triangles

Area of the square four = a² + b² + 2ab

Hence the area of the square four is a² + b² + 2ab
