Find the surface area of each figure. Round to the nearest tenth if necessary.​

Answer:

99

Step-by-step explanation:

4x³-2x²+3x​

4×3³-2×3²+3×3

4(27)-2(9)+9

108-18+9

99

99

=(4)(27)−2(32)+(3)(3)

=108−2(32)+(3)(3)

=108−(2)(9)+(3)(3)

=108−18+(3)(3)

=90+(3)(3)

=90+9

=99

Answer:

A. x/5 - 6 > -4

Step-by-step explanation:

The graph shows that x > 10. We need to solve each of the inequalities. After we do, we see that A is the answer.

A. x/5 - 6 > -4

x/5 > 2

x > 10

Answer:

-1280.0

Step-by-step explanation:

It is a whole number

if you want to show it as a decimal,

put ' .0 ' at the end of the whole number. That is,

=> -1280.0

Answer:

y=3x - 1

Step-by-step explanation:

we are going to base the answer off of the y=mx+b form where m represents slope and b represents the y-intercept.

we know that b must be -1 because the line hits the y-axis when y is -1

this now leaves us with either the first or second choice

we then choose two points to find the slope. I am using (0,-1) and (1,2). If you count the boxes, the y-value increases by 3 as the x-value increases by 1. So the slope is 3/1 or 3.

so then we know the answer is y=3x-1

Answer:

7.92 m.

Step-by-step explanation:

Mean height = ∑(f . x) / ∑f  where  x is the midpoint and f the frequencies

The midpoints for the heights are:

2 for frequency 8              ( 0 + 4)/ 2 = 2

6 for      ..           21

10 for    ..            12

14 for    ..              7

18 for   ..               2

So the mean is:

[(2*8) + (6*21) + (10*12) + (14*7) + (18*2) ] / (8 + 21+12+7+2)

= 396 / 50

= 7.92 m.

Answer:

Step-by-step explanitions:

this is true The central limit theorem holds true only for populations that are normally distributed.

this is also true For an infinite number of samples, 95% of the sample means would fall within the interval .

As the number of sample means decreases, the means get closer to a standard normal distribution.thsis is false

Answer:

228

Step-by-step explanation:

We are asked to convert 14 1/4 pounds into ounces, to do so, we need to multiply the amount of pounds by 16.

14 1/4 or 14.25

14.25 * 16

==> 228

Meaning there are 228 ounces in 14 1/4 pounds

Answer:

1.55

Step-by-step explanation:

0.21 is the probability you beat your sister given that you beat your brother at checkers

It is a branch of mathematics that deals with the occurrence of a random event.

Given,

The probability of beating your brother at checkers is 0.54

The probability of beating your sister at checkers is 0.48

The probability of beating your sister and brother at checkers is 0.33

We need to find the probability you beat your sister

probability you beat your sister =0.33-0.54

=0.21

Hence, 0.21 is the probability you beat your sister given that you beat your brother at checkers

Answer:

[tex]y = 0.4x + 3.8[/tex]

Answer:

y = ± 15

Step-by-step explanation:

Given

y² = 225 ( take the square root of both sides )

[tex]\sqrt{y^2}[/tex] = ± [tex]\sqrt{225}[/tex]

y = ± 15

That is y = 15, y = - 15

Since 15 × 15 = 225 and - 15 × - 15 = 225

y² = 225

y = √225

y = 15

y²= 225

y = √225

y = -15

y = ±15

Therefore values of y are 15 and -15

Answer:34

Step-by-step explanation:just add the percents

Answer:

C. 26%

Step-by-step explanation:

We can sort students into three categories: Football Only, Baseball Only, and students who play Both.

Firstly, let's turn the percentages into numbers to make the calculations easier:

To find 22% convert into decimal and multiply:

0.22 x 200 = 44 TOTAL Football players

Similarly, 0.12 x 200 = 24 TOTAL Baseball players.

The question then tells us that 8 students play both.

This means there are 44-8 = 36 students who play ONLY football, and

24-8= 16 students who ONLY play baseball:

Football Only:      Both:     Baseball Only:

        36                  8                   16

44 Total Football and    24 total baseball

The question asks the probability of a student playing EITHER football OR baseball which therefore does not include the students who play both.

Now we can add up all these numbers of students which gives us:

36 + 16 = 52

Now to find the percentage we just divide 52 by 200:

52/200 = 0.26 which is equivalent to 26%.

Therefore the answer is C. 26%

Answer:

$17,000 at 14% and $9,000 at 2%

Step-by-step explanation:

Let x = amount invested at 14%.

Let y = amount invested at 2%.

x + y = 26000

0.14x + 0.02y = 2560

     -0.02x - 0.02y = -520

(+)    0.14x + 0.02y = 2560

-------------------------------------

       0.12x              = 2040

x = 17,000

x + y = 26000

17000 + y = 26000

y = 9000

Answer: $17,000 at 14% and $9,000 at 2%

Answer:

25+10y

Step-by-step explanation:

The area of a rectangle is

A = l* w where l is the length and w is the width

A = 5(5+2y)

Distribute

A = 25+10y

Area of rectangle = Length * Width

Length is 5

Width is 5 + 2y

⇛Area = 5(5+2y)

⇛Area = 25 + 10y
