Gary has 30 blueberry muffins which is 30%Of all blueberry muffins in her basket how many muffins are in her basket

Answers

Answer:

100

Step-by-step explanation:

If 30% of all of her muffins are blueberry muffins, that means that 30% of 100% are blueberry. We want to find how many total muffins there are in her basket. Using a ratio:

30 muffins        30%

-----------------  =  --------

x muffins         100%

Cross multiply:

30 (100) = 30 (x)

3000 = 30x

3000/30 = 30x/30

100 = x

x muffins = 100 muffins

So there are a total of 100 muffins in Gary's basket.

To investigate whether or not sending text messages while driving impacts driving ability, we had 100 participants (50 men and 50 women) drive an obstacle course under one of the following conditions: 1) no texting while driving, 2) sending five text messages while driving, or 3) sending 10 text messages while driving. We measured the accuracy with which the subjects drove the obstacle course from a scale of 1 to 10 (1 = poor and 10 = excellent).We are testing the effect of sending text messages at three different _____.

a. treatments
b. levels
c. factors
d. None of the above

Answer:

A - treatments

Step-by-step explanation:

We are told the 100 participants were required to drive under 1 of the 3 conditions below which are;

- no texting while driving.

- sending five text messages while driving

- sending 10 text messages while driving

In experimental a research, these 3 conditions are referred to as treatments because they are used to derive an experimental result.

Which of the following equations represents a line that is perpendicular to the line represented by x + 2y = 6 and passes through the point (3 , –4)?

Answers

Answer:

y=2x-10

Step-by-step explanation:

First change to equation into slope intercept form

2y=-x+6

y=-1/2x+3

slope=2 (beacause it is perpendicular)

y--4=2(x-3)

y+4=2x-6

y=2x-10

What is the equation of 35?​

Answers

35 - X = 5

Simplifying

35 + -1X = 5

Solving

35 + -1X = 5

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '-35' to each side of the equation.

35 + -35 + -1X = 5 + -35

Combine like terms: 35 + -35 = 0

0 + -1X = 5 + -35

-1X = 5 + -35

Combine like terms: 5 + -35 = -30

-1X = -30

Divide each side by '-1'.

X = 30

Simplifying

X = 30

Walk
a) Complete the tree diagram.
b) Show that the probability that Lyn
walks at least one way is 0.88.​

Answers

I’m forced to write an explanation, sorry for the useless text

The probability tree has been drawn below and the  probability that Lyn

walks at least one way is 0.88 is when she reaches the shop by bus and from the bus, she walks.

What is probability?

The probability of an event occurring is defined by probability.

Do not take underestimate probability it has several uses in daily life whether forecasts like that.

As per the given probability tree,

(a)

The probability in branches adds to 1 thus,

0.2 + probability that she walks to the shop = 1

Probability that she walks to the shop  = 1 - 0.2 = 0.8

The probability in the same branches multiplies as,

The probability that she took a bus to the shop x from the bus she again took the bus.

Similarly, the tree diagram has been drawn below.

(b)

The probability is 0.88 lies in that Lyn walks at least one way 0.88 is when she reaches the shop by bus and from the bus, she walks.

Hence "walks at least one way is 0.88 is when she reaches the shop by bus and from the bus, she walks".

Step-by-step explanation:
volume of a rectangular prism is V=LWH
L is length and that is 20
W is width and that is 20
H is height and that is 6
The reason that L and W are 20 is because you would multiply those to get the base, and the base is already given, 400.
Since you know the volume is 2,400, a quick trick is that you divide 2,400/400. That equals 6.
So 20 x 20 x 6 = 2400

Roshanda was curious if students in her class would complete a maze faster if fast-paced music was playing in the background. She randomly assigned each student in her class to one of three groups: fast-paced music, slow-paced music, or no music. She timed each student as they individually completed a maze with their corresponding music (or no music) in the background. Students who worked with the fast-paced music, on average, completed the maze significantly faster than students in the other groups.
Can we conclude that the fast-paced music caused her classmates to finish the maze faster? Why?

(A) Yes, because the study included each student in her class

(B) Yes, because the adults were randomly selected

(C) Yes, because the students were randomly assigned to treatment and control groups

(D) Not necessarily, because the sample size was too small

(E) Not necessarily, because this wasn't an experiment

Answers

Answer: (E) Not necessarily, because this wasn't an experiment

Step-by-step explanation:

As much as the results would suggest that the fast-paced music was responsible for the faster finishing time, this conclusion cannot be authoritatively made because this was not technically an experiment but rather a test to satisfy curiosity.

An experiment is planned and is scientific. It has more stringent requirements that ensure causation that Roshanda did not meet before she engaged in this trial so we cannot say for a fact that her findings are objective.

Answer: C. yes, the students were randomly assigned to treatment and control groups.
