start one hour later. The school has 250 students. Make

an estimate, based on Andre's survey for the number of

students in the school who are in favor of having school

start one hour later.

O 65 students

O 87 students

163 students

170 students

Answers

Answer 1

Answer: 163 students

Step-by-step explanation:

First find the percentage of students who were in favor of having school  start one hour later based on the sample of 20 students.

= 13/20 * 100%

= 65%

The apply this percentage to the total number of students in school to find your answer:

= 65% * 250 students

= 162.5

= 163 students

Answer 2

The number of students in the school who are in favor of having school start one hour later is; C: 163 students

What is the random sample?

We are told that 13 out of the 20 surveyed students were in favour of having school start one hour later. Thus;

Probability = 13/20 * 100% = 65%

Now, the school has 250 students and as such, the number of students in the school who are in favor of having school start one hour later is;

65% * 250 students = 162.5 ≈ 163 students

Identify the independent and dependent variables in this proposed study. Group of answer choices The dependent variable is keyboard design; the independent variables are the speed of typing and the chime. The dependent variable is the number of errors made; the independent variables are the chime and the speed of typing. The dependent variable is the chime; the independent variables are the chime and typing speed. The dependent variable is speed of typing; the independent variables are the keyboard design and the chime.

Answers

Answer:

The dependent variable is speed of typing; the independent variables are the keyboard design and the chime.

Step-by-step explanation:

The variable which we intend to measure or determine is called the dependent or predicted variable. However, to predict or measure the dependent variable, one or more variables are required, these are the variables whose different values or input affects the outcome of the dependent variable, these variables are called the independent variable.

In the scenario described above, the dependent variable is typing speed as it is the variable we intend to measure or determine using the new keyboard design and chime as the predictor variables.

Answers

Answer:

79.2 units

Step-by-step explanation:

Tangents to a circle from an external point are congruent , then

PQ = 27.4

QR = 5.9 + 12.2 = 18.1

PR = 12.2 + (27.4 - 5.9 ) = 12.2 + 21.5 = 33.7

Then

perimeter = PQ + QR + PR = 27.4 + 18.1 + 33.7 = 79.2

Maxine can swim 240 meters in 4 minutes. What is Maxine's unit rate?

Answers

Answer: A) 18.2 minutes
B) 4.5 minutes.
Step-by-step explanation:
A) Maxine can mow one lawn in 24 minutes, so the rate of work is:
1/24 of the lawn per minute.
Sammie can mow one lanw in 36 minutes, so the rate of work is:
1/36 of the lawn per minute.
The amount of the lawn that each has left to lawn by the minute x is:
Maxine = 1 -(1/24)*x
Sammie = 1 - (1/36)*x
we want to find the value of x such that:
2*(1 - (1/24)*x) = 1 - *(1/36)*x
which means that the amount that Sammie has left is two times the amount that Maxine has left to mow.
2 - (1/12)*x = 1 - (1/36)*x
2 - 1 = (1/12 - 1/36)*x
1/0.055 = x = 18.2
by the minute 18.2
B) Similar to before, here the rates are:
For Maxine, R = 1/6
For Sammie, R = 1/9
The amount they have left to mow by minute x is:
Maxine = 1 - (1/6)*x
Sammie = 1 - (1/9)*x
We want to solve, similar to before.
2( 1 - (1/6)*x) = 1 - (1/9)*x
2 - (1/3)*x = 1 - (1/9)*x
2 - 1 = (1/3 - 1/9)*x
1 = (2/9)*x
1*9/2 = x = 4.5
So here the solution is 4.5 minutes. Hope this helps

Thirty students in an art class each receive an identical set of 20 markers. As part of a project, each student is asked to close their eyes and select from his or her set at random. You developed a model that predicts the probability of a student randomly picking a yellow marker is 0.1. Which result would most likely cast doubt on your model? (Hint: what is the theoretical probability of 30 students choosing a yellow marker each from a pack of 20 markers.)

10 student pick red markers.
10 student pick yellow markers.
2 student pick blue markers.
2 student pick yellow markers.
3 students pick yellow markers.
3 students pick green markers.

Answers

okay 1 student = 1/20 chance of picking yellow

1/20 (30/30) = 30/600 chance of picking yellow out of 30 studnets

30/600 = 0.05 = 5% chance of choosing yellow.

I each studnet picks 1 yellow marker. Is that all the options?

Simplify a: 6x+7=4x+7 ~ No matter what, this cannot be possible

Simplify b: 6x=4x ~ Once again, this is impossible unless x=0, but I'll assume it can't be for now

Simplify c: 4x+7=4x+7 ~ This clearly is a correct statement, this it is c

Simplify d: 6x-1=4x+1 ~ By subtracting 4x on each side, then adding 1 on both sides, we get 2x=2, so x can be 2.

Step-by-step explanation:

Breakeven quantity are the number of  units produced and sold at which net income is zero

Breakeven quantity = fixed cost / price – variable cost per unit

Fixed costs are costs that do not vary with output. e,g, rent, mortgage payments

If production is zero or if production is a million, Mortgage payments do not change - it remains the same no matter the level of output.  

Hourly wage costs and payments for production inputs are variable costs

Variable costs are costs that vary with production

fixed cost = $2450

Variable cost = $75

price = $145

(2450) / (145 - 75) = 35

Stanley needs 31 feet and 2 inches of fencing.

Step-by-step explanation:

In order to answer this problem, you need to find the perimeter of the dog run.

Since: [tex]P=2(l+w)[/tex]

and [tex]l=149[/tex] inches & [tex]w=56[/tex] inches

Plug in what we know :

[tex]P=2(149+56)[/tex]

and solve:

[tex]P=410[/tex] inches

The dog run has a perimeter of 410 inches.

However, now we need to subtract 36 inches since the gate doesn't need fencing.

[tex]410-36=374[/tex] inches.

The dog run needs 374 inches of fencing.

In order to find out how many feet of fencing that is, divide it by 12.

[tex]\frac{374}{12}[/tex] = 31.16666667 OR [tex]31\frac{2}{12}[/tex], meaning 31 feet and 2 inches.

Answer:

31 feet and 2 inches of fencing :))<3

Yes, The statement ''If an event is certain to​ occur, its probability is 1'' is true.

What is mean by Probability?

The term probability refers to the likelihood of an event occurring.

Given that;

The statement is,

''If an event is certain to​ occur, its probability is 1.''

Now,

Since, The event that is sure to happen is called a certain event and probability of such an event is 1 as this event is bound to happen.

Thus,  The statement ''If an event is certain to​ occur, its probability is 1'' is true.

KP is a radius of the circle. Is JK tangent to the circle? Note the figure may not be drawn to scale.

Answers

Answer:

JK is NOT tangent to the circle

Step-by-step explanation:

A tangent of a circle is a line that intersects a circle at one and only one point. For this reason, the radius will always intersect a tangent at a 90 degree angle to prove this single point intersection. From the triangle, we can introduce the Pythagorean theorem to see if the triangle is a right triangle:

a^2 + b^2 = c^2

48^2 + 14^2 = 36^2

2304 + 196 = 1296

2500 ≠ 1296

As this is not equal, the triangle is not a right triangle and therefore states that the tangent line does not intersect the radius at 90 degrees, meaning that it does not satisfy the requirements of a tangent line.
