Step-by-step explanation:

[tex]3a + 2b + c = 3(7) + 2(5) + 5 \\ = 21 + 10 + 5 \\ = 36 \\ \sqrt{3a + 2b + c} = \sqrt{36} \\ = 6[/tex]

The square root of 3a + 2b + c is 6.

The square root of a number is the factor that we can multiply by itself to get that number.

Now the given expression is,

3a + 2b + c

Now square root of 3a + 2b + c is given as,

√(3a + 2b + c)

Putting, a = 7, b = 5 and c = 5 in the given expression we get,

√(3a + 2b + c) = √(3*7 + 2*5 + 5)

Multiplying we get,

⇒ √(3a + 2b + c) = √(21 + 10 + 5)

Adding we get,

⇒ √(3a + 2b + c) = √36

Since, √36 = 6

Therefore,

⇒ √(3a + 2b + c) = 6

which is the required value of the square root.

Thus, The square root of 3a + 2b + c is 6.

Highest Common factor of 12, 16 and 48 is 4

Answer:

highest common factor of 12, 16 and 48 is 4.

Answer:

2014 price was $49,091

Step-by-step explanation:

I'm assuming you want to solve for 2014 year price...

2015 year price is 54,000 and was 10% higher than 2014 price, meaning 2015 price is 110% of 2014 price so...

p×110%=54,000

p=54,000/1.1

p=49,090.90

Answer:

29.85%

Step-by-step explanation:

total amount of students who took the math test

20 + 40 + 7 = 67

the percentage of students who got 90 and above in the math test

20 ÷ 67 × 100 = 29.85%

Answer:

29.85%

Step-by-step explanation:

Firstly, calculate how many students took the math test.

20 + 40 + 7 = 67

Then locate how many students got the score of 90 or above.

20

So you can say that, 20/67 got a 90 or above.

Convert 20/67 to a percent:

So, 29.85%

The given histogram is Negatively skewed, and the mean is to the right of the median.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

For a symmetric histogram, the values of the mean, median, and mode are all the same and are all located at the center of the distribution.

A negatively skewed distribution is a type of distribution in which more values are concentrated on the right side of the distribution graph while the left tail of the distribution graph is longer

The data distributed where is the mean located in relation to the median is to the right side.

Hence, the given histogram is Negatively skewed, and the mean is to the right of the median.

Answer:

For values of p < 0.6, it may be desirable to foul the shooter.

Step-by-step explanation:

Suppose an NBA basketball player shooting an un- contested 2-point shot will make the basket with probability 0.6.

This means that the amount of points he expects to score with the ball in his hand is:

2*0.6 = 1.2

Based on the expected number of points the shooter will score, for what values of p may it be desirable to foul the shooter?

The expected number of points he will score with these free throws is:

2p

In which p is the probability of making the free throw.

If will be desirable to foul the shooter is:

[tex]2p < 1.2[/tex]

[tex]p < \frac{1.2}{2}[/tex]

[tex]p < 0.6[/tex]

For values of p < 0.6, it may be desirable to foul the shooter.

Answer:

The height of the jar is 1.75.

Step-by-step explanation:

Given that the volume of the jar is 88, and it has a radius of 4, to determine what is the height of the jar, the following calculations must be performed, knowing that the volume of a cylinder arises from multiplying pi by the radius squared, and multiplying that result by the height:

3.14 x 4 ^ 2 x H = 88

3.14 x 16 x H = 88

50.24 x H = 88

H = 88 / 50.24

H = 1.75

Thus, the height of the jar is 1.75.

Answer:

32 slabs are needed

Step-by-step explanation:

If the pond is 8m by 8m, then that means each side is equal, and each side is 8m long. There are 4 sides to the perimeter of the pond. To find how many slabs you need, you need to found out how many meters long the perimeter of the pond is in total. To do so, you must multiply the length of one side of the perimeter to the number of sides there is. The length of one side of the perimeter is 8m, and the number of sides is 4, which means you must multiply 8 by 4, which equals 32.

Answer:

y = -5/2x + 20/3

Step-by-step explanation:

x-int of 3x + 6y = 8

sub 0 for y

3x + 6(0) = 8

3x = 8

x = 8/3 or 2.667

line perpendicular to 2x - 5y = 10

put into y = mx + b form

2x - 5y - 10 = 0

5y = 2x - 10

y = 2/5 x - 2

find negative reciprocal of the slope 2/5 x (for the perpendicular line)

-5/2 x

find the y-int (b)

m = -5/2 x

must pass through (8/3,0)

y = mx + b

0 =  -5/2(8/3) + b

0 = -40/6 + b

b = 20/3

therefor the equation of the line is y = -5/2x + 20/3
