Answer:

period = 2

Step-by-step explanation:

The period is the measure of 1 complete cycle of the wave

The wave enters at x = 0 , y = - 0.5

After 1 cycle the wave is at x = 2, y = - 0.5

period = 2 - 0 = 2

Find the perimeter of the figure to the nearest hundredth.

Alenkinab [10]

Answer: 48.84

Step-by-step explanation:

First, find the perimeter of the rectangle. 12+12+3+3=30ft. Next, find the perimeter of the semicircles. You can tell that if you put the semicircles together it would be a full circle. The formula for the perimeter of a circle is r2pi. The radius times 2 would be 6. Pi is approximately 3.14. 6 times 3.14 is 18.84. 18.84+30=48.84ft. Hope this helped :)

Answer:

money market: $1000
stock: $238,500
mutual fund: $228,500

Step-by-step explanation:

We can let x and y represent the amounts invested in the stock and mutual fund, respectively. Then the amount invested in the money market account was (468000 -x -y). Two relations can be written.

x = y + 10000 . . . . . 10,000 more was invested in stock than in mutual funds

0.035(468000-x-y) +0.04(x) -0.03(y) = 2720 . . . . first-year return

Collecting terms in the second equation gives ...

0.005x -0.065y +16380 = 2720

-x + 13y = 2732000 . . . . . . subtract 16380, multiply by -200

12y -10000 = 2732000 . . . . substitute for x using the first equation

y = 2742000/12 = 228,500 . . . . solve for y

x = 228,500 +10,000 = 238,500 . . . . . find x from the first equation

468,000 -x -y = 468,000 -467,000 = 1,000 . . . . find the money market amount

Pierre invested $1000 in the money market account, $238,500 in the stock, and $228,500 in the mutual fund.

The probability of winning on an arcade game is 0.659. if you play the arcade game 30 times. What is the probability of winning

stealth61 [152]

The probability of winning exactly 21 times is 0.14 when the probability of winning the arcade game is 0.659.

We know that binomial probability is given by:

Probability (P) = ⁿCₓ (probability of 1st)ˣ x (1 - probability of 1st)ⁿ⁻ˣ

We are given that:

Probability of winning on an arcade game = P(A) = 0.659

So, the Probability of loosing on an arcade game will be = P'(A) = 1 - 0.659 = 0.341

Number of times the game is being played = 30

We have to find the Probability of winning exactly 21 times.

Here,

n = 30

x = 21

P(A) = 0.659

P'(A) = 0.341

Using the binomial probability formula, we get that:

Probability of winning exactly 21 times :

P(21 times) = ³⁰C₂₁ (0.659)²¹ x (0.341)⁷

P( 21 times ) = 0.14

Therefore, the probability of winning exactly 21 times is 0.14

Shana bought sodas and popcorn for the movies. Sodas cost $3 each and popcorn cost $4 per bag. Shana bought 7 things from the co

erma4kov [3.2K]

Equation : 3s + 4p = $26
Answer : 2 sodas and 5 bags of popcorn.
The equation would be 3s + 4p = $26. 3s is the $3 for every soda and 4p is $4 for every bag of popcorn.
Shana bought 2 sodas and 5 bags of popcorn. 3 x 2 is 6 and 5 x 4 is 20 which would equal $26. They also equal to the 7 things because of the 2 sodas and 5 bags.

Compute the following volume and surface area.

Vesnalui [34]

The surface area of rectangular solid is 208 square centimeter

The volume of rectangular solid is 192 cubic centimeter

<h3><u>Solution:</u></h3>

Given that rectangular solid has sides of 4 cm, 6 cm, and 8 cm

To find: surface area and volume of rectangular solid

Length = l = 4 cm

Width = w = 6 cm

Height = h = 8 cm

<h3><em><u>The formula to find the surface area of a rectangular prism is:</u></em></h3>

Surface Area = 2wl + 2lh + 2hw

where w is the width, the l is the length, and the h is the height.

$\text {surface area }=2(4 \times 6)+2(4 \times 8)+2(8 \times 6)\\\\\text {surface area } = 2(24) + 2(32) + 2(48)\\\\\text {surface area } = 48 + 64 + 96 = 208$

Thus the surface area of rectangular solid is 208 square centimeter

<h3><em><u>The formula for volume of rectangular solid is:</u></em></h3>

$Volume = Length \times Height \times Width$

$volume = 4 \times 6 \times 8 = 24 \times 8 = 192$

Thus the volume of rectangular solid is 192 cubic centimeter
