Help please!!!!!! I can’t figure it out.

Answer:

the answer is 30 with 75 kids voting for drinks in total

Answer:

30 students

Step-by-step explanation:

45 divided 3 (the numerator of 3/5) is 15 so 1/5 is 15. 5 minus 3 =2. so 2/5 students picked sprite. and 15 times 2 equals 30. easy

Answer:

0.49

Step-by-step explanation:

We apply conditional probability to solve this question.

We have Events X and Events Y

P(X) = Probability Christine fails the course = ??? Unknown

P(Y) = Probability Christine finds a tutor

= 0.35

P(Y') = Probability Christine does not find a tutor = 1 - 0.35 = 0.75

P(X|Y) = Decrease in her probability of failing = 0.35

P(X|Y') = Probability that she will fail the course if she does not have a tutor

P(X) = P(X|Y) × P(Y) + P(X|Y') × P(Y')

P(X) = 0.35 × 0.75 + 0.65 × 0.35

P(X) = 0.2625 + 0.2275

P(X) = 0.49

The probability that Christine fails the course is 0.49

Answer:

y=-2x+b

-2=-8+b

6=b

y=-2x+6

so

2x+y=6

Answer:

True : It is an example of a continuous variable

Step-by-step explanation:

Numerical variables acn be classed as either being discrete or continuous based on whether the values in the data set are finite and countable or not.

Discrete variables are characterized by possessing a finite number of possible values which are countable and usually do not involve decimal numbers in between successive whole numbers.

On the other hand continuous variables are non finite and usually contains a lot of points in between possible whole numbers such as in the scenario above, the race time for the students take up any number within minutes, seconds and milliseconds. Hence, making the possible Numner of values impossible to predict or state.

Answer:

1040

Step-by-step explanation:

The fish tank problem:

x = # of days

180 - 8x = 160 - 6x

Add 8x to both sides and subtract 160 from both sides.

20 = 2x

Divide both sides by 2

10 = x

It will take 10 days for the fish tanks to have the same amount of water in them.

The sand castle problem:

x = # of minutes.

180 - 8x = 160 + 6x

Add 8x to both sides and subtract 160 from both sides.

20 = 14x

Divide both sides by 14

x = 10/7 mins

After 10/7 mins their sand castles will be the same height

Answer:

Point D

Point D is at 2, the absolute value of -2.

2 is the opposite of -2, and D is at 2.

So, the answer must be option D.

Answer:

20/25

Step-by-step explanation:

to get to a dinominator of 25, we have to multiply 5 by 5. so then we do 4 x 5 so now it is 20/25

Answer:

0.0657534

Step-by-step explanation:

divide 2 by 30.417

The measurement of ∠KNL   is 102°

First, you must set up an equation to find x.

[tex]5x+2=[3(x+14)[/tex]

Then, you must simplify both sides of the equation.

[tex]5x+2=3x+42[/tex]

Next, subtract 3x on both sides.

[tex]2x+2=42[/tex]

Then, subtract 2 on each side.

[tex]2x=40[/tex]

Next, divide 2 on each side.

[tex]x=20[/tex]

Now that we have the value of x, we can substitute it in for angle KNL.

[tex][3(20+14)][/tex]

[tex][3(34)][/tex]

[tex]102[/tex]

[tex]102[/tex]°

768 square meters.

We can break it down into two shapes, a rectangle and a triangle.

Rectangle:

[tex]a = b \times h[/tex]

[tex]a = (48) \times (11)[/tex]

[tex]a = 528m^{2} [/tex]

Triangle:

[tex]a = \frac{b \times h}{2} [/tex]

[tex]a = \frac{(48) \times (10)}{2} [/tex]

[tex]a = \frac{480}{2} [/tex]

[tex]a = 240m^{2} [/tex]

Add them together:

[tex]528m^{2} + 240m^{2} = 768m^{2} [/tex]

Answer:

23 did i get it?

Answer:

The correlation coefficient  is r = 0.52

Step-by-step explanation:

From the question we are told that

            The correlation coefficient  is r = 0.52

 Generally correlation has no unit and is not affected by unit (i.e it show the ratio between two quantities )

Hence a change of the unit of measurement of  length from cm to mm will not affect the correlation coefficient r hence the value will still remain  r = 0.52

Answer:

Rise over run.

Step-by-step explanation:

If you have learned rise over run you will get it.

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

P(brown) = 12% = 0.12

P(Yellow) = 15% = 0.15

P(Red) = 12% = 0.12

P(blue) = 23% = 0.23

P(orange) = 23% = 0.23

P(green) = 15% = 0.15

A.) Compute the probability that a randomly selected peanut M&M is not yellow.

P(not yellow) = P(Yellow)' = 1 - P(Yellow) = 1 - 0.15 = 0.85

B.) Compute the probability that a randomly selected peanut M&M is brown or red.

P(Brown) or P(Red) :

0.12 + 0.12 = 0.24

C.) Compute the probability that three randomly selected peanut M&M’s are all brown.

P(brown) * P(brown) * P(brown)

0.12 * 0.12 * 0.12 =0.001728

D.) If you randomly select three peanut M&M’s, compute that probability that none of them are blue.

P(3 blue)' = 1 - P(3 blue)

P(3 blue) = 0.23 * 0.23 * 0.23 = 0.012167

1 - P(3 blue) = 1 - 0.012167 = 0.987833

If you randomly select three peanut M&M’s, compute that probability that at least one of them is blue.

P(1 blue) + p(2 blue) + p(3 blue)

(0.23) + (0.23*0.23) + (0.23*0.23*0.23)

0.23 + 0.0529 + 0.012167

= 0.295067
