Helpppp I need this done

Answer:

A'=(5/2,-5/2)

therefore A'(2.5,-2.5)

Step-by-step explanation:

Answer:

20.32$

Step-by-step explanation:

25.40×.20 = 5.08

25.40- 5.08 = 20.32

so the answer would be 20.32$

the answer should be 19 I believe

Answer:

measure of Angle 7 would also be (3y - 8), by the alternate exterior angles theorem

Hope this helps!

Answer:

83.3

Step-by-step explanation:

Answer:

7. 1520.53 cm²

8. 232.35 ft²

9. 706.86 m²

10. 4,156.32 mm²

11. 780.46 m²

12. 1,847.25 mi²

Step-by-step explanation:

Recall:

Surface area of sphere = 4πr²

Surface area of hemisphere = 2πr² + πr²

7. r = 11 cm

Plug in the value into the appropriate formula

Surface area of the sphere = 4*π*11² = 1520.53 cm² (nearest tenth)

8. r = ½(8.6) = 4.3 ft

Plug in the value into the appropriate formula

Surface area of the sphere = 4*π*4.3² = 232.35 ft² (nearest tenth)

9. r = ½(15) = 7.5 m

Surface area of the sphere = 4*π*7.5² = 706.86 m² (nearest tenth)

10. r = ½(42) = 21 mm

Plug in the value into the formula

Surface area of hemisphere = 2*π*21² + π*21² = 2,770.88 + 1,385.44

= 4,156.32 mm²

11. r = 9.1 m

Plug in the value into the formula

Surface area of hemisphere = 2*π*9.1² + π*9.1² = 520.31 + 260.15

= 780.46 m²

12. r = 14 mi

Plug in the value into the formula

Surface area of hemisphere = 2*π*14² + π*14² = 1,231.50 + 615.75

= 1,847.25 mi²

Answer:

It should look something like what I attached

Hope this helps!! :)

Answer:

I believe its 16.

Step-by-step explanation:

Because 2 x 2 (for the square) is 4. 2 x 3 is 6, and 6 divided by 2 is 3. And 3 x 4 (for all the triangles) is 12. So 12 + 4 is 16. So the surface area should be 16.

Answer:

B-It will decrease in volume

Step-by-step explanation:

If I am not mistaken, the water, if left in the sun, will evaporate when heated, so the volume will decrease.

Answer:

1/6

Step-by-step explanation:

A standard dice has 6 numbers. Convert it as a fraction, and you get 1/6 per probability of a number.

Answer:

50.0 cm²

Step-by-step explanation:

Applying

Volume of a pyramid (V) = 1/3×Area of the base(A')×Heigth(H)

A= 1/3A'h.................... Equation 1

A' = Area of the base, h = height of the pyramid

From the question,

Given: A' = 12.2 m², h = 12.3 m

Substitute these values into equation 1

A = 1/3(12.2×12.3)

A = 50.02

A = 50.02 cm²

A = 50.0 cm²

Answer:

D) Simultaneously compare several population means.

Step-by-step explanation:

ANOVA (Analysis of Variance) was developed by Ronald Fisher.

ANOVA ie Analysis of Variance, is collection of statistical models & linked estimation processes, like variation among & between groups. It is used in analysing differences among various means.

So, it is used to : D) Simultaneously compare several population means.

Nominal Data, t test, population proportions are not uses of ANOVA.

HOPE THIS HELPSS!!!!!

Step-by-step explanation:

So the exact value of the area is A=100π A = 100 π square inches. To approximate the area, we would substitute π≈3.

Answer:

1/16m per minute

Step-by-step explanation:

If Milan fills the aquarium to a depth of 3/8 in 6 minutes then just divide 3/8 by 6 to find how much she fills in 1 minute

Step-by-step explanation:

for mixed number to a improper fraction you take the whole number and times that by the denominator and add the numeriator

for example

[tex]8 \frac{3}{8} [/tex]

8 x 8 = 64

64 + 3 = 67

and after you get your last number (67) you put that over your original denominator which is 8 so it would be

[tex] \frac{67}{8} [/tex]

for the improper to mixed you see how many times you denominator goes into your numerator

another example is

[tex] \frac{13}{7} [/tex]

7 goes into 13 twice so your whole number is 2 and you have a remaining 1 so it would look like

[tex]2 \frac{1}{7} [/tex]

Answer:

A) 9/4

B) 67/8

C) 17/6

D) 9/2

E) 16/3

F) 127/12

G) 37/4

H) 41/6

Q) Whole Number: 1 Fraction: 6/7

R) Whole Number: 4 Fraction: 1/2

S) Whole Number: 1 Fraction: 8/9

T) Whole Number: 2 Fraction: 1/3

U) Whole Number: 2 Fraction: 3/7

V) Whole Number: 3 Fraction: 1/3

W) I am not 100% sure for this one but I think it's right.

Mixed Number - Whole Number: 1 Fraction: 5/8

Improper fraction - 13/8

Step-by-step explanation:

With improper fractions the first thing that you want to do is multiply the whole number with the denominator (the number on the bottom of the fraction), then add the numerator (the number on the top of the fraction). You also want to keep the denominator the same in both fractions.

When working with converting mixed fractions into improper fractions it is kind of the opposite, but it is a little harder to explain. Let's take letter Q as an example. If you know that you cannot divide the numerator and the denominator in anyway to make a whole number, the whole number will become a one and the numerator is how many are left. so in this case the answer for Q would be 1 6/7, 1 being the whole number and 6 from 6+7=13. now let's look at letter R, you know you can divide 2 four times into 9, the whole number will be 4 and the fraction will be 1/2, 4x2+1=9. You can also double check that you did it right by turning it back into a improper fraction from the mixed number state by multiplying the denominator with the whole number, then adding the numerator. Hope that made sense, send me a DM if you need more help!

Answer:

A ton is 2,000 pounds, so the answer is 24 Tons

Answer:

24 tons

Step-by-step explanation:

1 ton = 2,000 pounds

[tex]\frac{1}{2,000} :\frac{y}{48,000}[/tex]

y × 2,000 = 48,000 × 1

2,000y = 48,000

2,000y ÷ 2,000 = 48,000 ÷ 2,000

y = 24

Answer:

The length of the line segment PZ is 32 units.

Step-by-step explanation:

If P is the circumcenter of [tex]\triangle XYZ[/tex], then the measures of line segments PX, PY and PZ are the same of the radius of the circle, in which is inscribed in, meaning that measures of the three line segment are equal:

[tex]PX = PY = PZ[/tex] (1)

If we know that [tex]PX = 3\cdot x + 2[/tex] and [tex]PY = 4\cdot x - 8[/tex], then we solve (1) for [tex]x[/tex]:

[tex]3\cdot x + 2 = 4\cdot x - 8[/tex]

[tex]x = 10[/tex]

Then, the length of PZ is:

[tex]PZ = 3\cdot x + 2[/tex]

[tex]PZ = 3\cdot (10) + 2[/tex]

[tex]PZ = 32[/tex]

The length of the line segment PZ is 32 units.

Answer:

n = 1100

Step-by-step explanation:

Isolate the variable, n. Note the equal sign, what you do to one side, you do to the other. Multiply 10 to both sides of the equation:

110 = n/10

(110) * 10 = (n/10) * 10

n = 110 * 10

n = 1100

1100 is your answer for n.

Answer:

1100 = n

Step-by-step explanation:

➟ 110 = n/10

➟ 110 × 10 = n

Answer:

0.188

Step-by-step explanation:

The computation is shown below;

First we have to determine the no of smokers

= Total no of persons - number of non-smokers

= 271 - 220

= 51

Now we have to estimate the proportion

So for this

= 51 ÷ 271

= 0.188192

= 0.188

Hence, the estimation is 0.188

The same is to be considered

Answer:

"0.9739" is the correct answer.

Step-by-step explanation:

The given values are:

The ratio of true to false effects,

= 0.07

The power of study,

= 0.8

Alpha level,

= 0.05

Now,

The percentage of effects proved as significant will be:

= [tex]0.8\times \ 70 \ percentage[/tex]

= [tex]0.56[/tex]

0r,

= [tex]56[/tex]%

The percentage of false effects will be:

= [tex]0.05\times 30 \ percent[/tex]

= [tex]0.015[/tex]

or,

= [tex]1.5[/tex]%

The total effects will be:

= [tex]56+1.5[/tex]

= [tex]57.5[/tex]%

hence,

The probability that this effect is real will be:

= [tex]\frac{56}{57.5}[/tex]

= [tex]0.9739[/tex]

Answer:

  7.5 square units

Step-by-step explanation:

The formula for the area of a trapezoid is ...

  A = 1/2(b1 +b2)h

where b1 and b2 are the lengths of the parallel bases, and h is the perpendicular distance between them.

Here, the bases are TR = 1 and PA = 4. The height is 3 units, so the area is ...

  A = (1/2)(1 +4)(3) = 15/2 = 7.5 . . . . square units
