Gerri Is Unsure Whether A Six-sided Number Cube Is Fair. She Rolls The Number Cube 35 Times And Records

Answers

Answer 1

Answer:

40%

Step-by-step explanation:

In order to calculate this probability we need to calculate the frequency of all the numbers rolled that were less than three. Since this would be numbers 1 and 2 and 1 was rolled 6 times while 2 was rolled 8 times, therefore, we add these numbers together.

6 + 8 = 14

Since we are tolled that the total number of rolls were 35, we now divide the number of rolls that were less than 3 (14 rolls) by the total number of rolls made (35 rolls). This would give us the probability of rolling a number less than 3

14 / 35 = 0.4  ... multiply by 100 to get percentage

0.4 * 100 = 40%

A school group is raising money for a trip. The group needs $450 for travel and $325 for food. They have 6 weeks to raise money selling $1 candy bars.
What is the least number of candy bars the group needs to sell each week to afford the trip?

Answers

Answer:

Step-In total, the amount of money they will need to raise is:

= 450 + 325

= $775

by-step explanation:

They have 6 weeks to raise this money so the amount they have to raise per week is at least:

= 775/6

= $130

The candy bars cost $1 each. They will therefore have to sell a minimum of 130 candy bars each week to afford the trip.

The periods when B = 0.5 and 2 are 4π and π, respectively

How to determine the period?

The period of a sine function is calculated using:

T = 2π/B

When B = 0.5, we have:

T = 2π/0.5

T = 4π

When B = 2, we have:

T = 2π/2

T = π

Hence, the periods when B = 0.5 and 2 are 4π and π, respectively

What expression can you use to find 17 divided by 4/5?

A: 4/5 divided by 16
B: 16 divided by 5/4
C: 16 times 5/4
D: 4/5 times 16

Answers

Answer: B) 16 times 5/4

Step-by-step explanation:

16 divided by 4/5 = 20

16 x 5/4 = 20

When a whole number like 16 is divided by a fraction such as 4/5, you multiply it by the reciprocal (flipped version) of the fraction. What is the reciprocal of 4/5? It's 5/4. From there, you can solve each equation to make sure they are equivalent to check.

Cars lose value the farther they are driven. A random sample of 11 cars for sale was taken. All 11 cars were the same make and model. A line was fit to the data to model the relationship between how far each car had been driven and its selling price.

Answers

Answer:

[tex]y=-\frac{1}{4}x+40[/tex]

Step-by-step explanation:

Given

See attachment for graph

Required

Determine the equation of the line of best fit

First, calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

From the graph, we can have:

[tex](x_1,y_1) = (20,35)[/tex]

[tex](x_2,y_2) = (60,25)[/tex]

So, the slope is:

[tex]m = \frac{25 -35}{60 - 20}[/tex]

[tex]m = \frac{-10}{40}[/tex]

[tex]m = -\frac{1}{4}[/tex]

The equation is then calculated as:

[tex]y = m(x - x_1) + y_1[/tex]

[tex]y = -\frac{1}{4}(x - 20) + 35[/tex]

[tex]y = -\frac{1}{4}x + 5 + 35[/tex]

[tex]y=-\frac{1}{4}x+40[/tex]

Hence, the equation is: [tex]y=-\frac{1}{4}x+40[/tex]

Explicación paso a paso:

Dado :

Frecuencia de onda = 60 Hz

Longitud de onda = 0,2 m

60 cars to 24 cars what is the decrease percentage​

Answers

Answer:

It decreased 60%

Step-by-step explanation:

TO figure this out we must first find 1% of 60

60/100 = .6

Now we find the difference between 60 and 24

60 - 24 = 36

Now that we know how much it decreased we must now find out what percent 36 is of 60.

.6 x 60 = 36

So 36 out of 60 is 60%

So it decreased 60%

Answers

Answer:

48 degrees

Step-by-step explanation:

1) Solve for x

Complementary angles add up to 90 degrees. Therefore, m<A + m<B is equal to 90:

[tex]A+B=90\\(2x+20)+(3x)=90[/tex]

Open up the parentheses

[tex]2x+20+3x=90\\5x+20=90[/tex]

Subtract 20 from both sides

[tex]5x+20-20=90-20\\5x=70[/tex]

Divide both sides by 5

[tex]\frac{5x}{5} =\frac{70}{5} \\x=14[/tex]

Therefore, x is equal to 14.

2) Determine angle A

[tex]A=2x+20[/tex]

Substitute x with 14

[tex]A=2(14)+20\\A=28+20\\A=48[/tex]

Therefore, the measure of angle A in degrees is 48 degrees.
