How do you solve for n? How do you find the rule? Please help me!

Answer:

67% or 0.67

Step-by-step explanation:

Given that:

P(1 child under age 21) = 55%

P(2 children under age 21) = 22%

P(3 children under age 21) = 15%

P(4 children under age 21) = 5%

P(5 or more children under age 21) = 3%

If a family is selected at random, what is the probability the family has 1 or 3 children under the age of 21?

P(1 or 3 children under age 21):

Either the selected family has 1 child under 21 years of age OR the selected family has 3 children under 21 years of age ;

P(1 child under age 21) + P(3 children under age 21)

= 55% + 15%

= 67% = 0.67

Answer:

x is greater than negative 4, and less than or equal to 5

Step-by-step explanation:

Answer: X is greater than negative 4 and less than 5

Step-by-step explanation: The line is from -4 to 5, the unfilled dot on top of -4 means the number can't be 4, it must be greater and the filled in dot on 5 means it is equal to or less than 5.

Answer:

[tex]\frac{5}{18}[/tex]

Step-by-step explanation:

sum the parts of the ratio, 4 + 5 = 9 parts

Divide the amount by 9 to find the value of one part of the ratio

£540 ÷ 9 = £60 ← value of 1 part of the ratio , thus

4 parts = 4 × £60 = £240 ← Alvin's share

5 parts = 5 × £60 = £300 ← Simon's share

[tex]\frac{1}{2}[/tex] × £240 = £120

[tex]\frac{1}{10}[/tex] × £300 = £30

Theo receives £120 + £30 = £150 , which as a fraction is

[tex]\frac{150}{540}[/tex] ( divide numerator/ denominator by 30 )

= [tex]\frac{5}{18}[/tex] ← in simplest form

The equation y = 6.5x will represent the situation and the unit rate will be $6.5/hour.

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

After that, we need to substitute the values of x's and y's into the coordinate geometry.

Given that,

Evan earned $26 for 4 hours of babysitting.

If total earnings y for babysitting x hours then,

y = (26/4)x ⇒ y = 6.5x will be the equation.

The unit rate of the function is y/x = $6.5/hour.

Hence "The equation y = 6.5x will represent the situation and the unit rate will be $6.5/hour".

Answer:

RT = 8

Step-by-step explanation:

The given parameters for the triangle are;

The vertices of the given triangle = RSQ

The point on the perpendicular bisector = Pont S and T

The length of the line segment RT = x

The length of the line segment TQ = 8

The length of the line segment QS = 10

The length of the line segment RS = 10

Given that I is a perpendicular bisector that passes through the vertex S, we have;

The line I bisects the segment RQ at point T into equal segments TQ and TR

Therefore, TQ ≅ TR and we have TQ = TR = 8

TR = 8

TR = RT (reflexive property)

Therefore; RT = 8.

Answer:

RS = 12

Step-by-step explanation:

if your question is asking for RS

Answer: The answer would be 2/11

Step-by-step explanation: Mark answered 54 questions correctly, so Mark missed 12 which gives you 12/66. Then that simplifies to 2/11

Answer:

x = -4

Step-by-step explanation:

2(x-8)=x+5x

Combine like terms

2(x-8) = 6x

Divide by 2

2(x-8)/2 = 6x/2

x-8 = 3x

Subtract x from each side

x-8-x = 3x-x

-8 = 2x

Divide by 2

-8/2 = 2x/2

-4 =x

Answer:

f(7)=140

Step-by-step explanations:

Slope can be calculated using the formula: m= [tex]\frac{y2 - y1}{x2 - x1}[/tex]

y1/x1 represents the first number in the bracket

y2/x2 represents the second number in the bracket

Calculation

m = [tex]\frac{y2 - y1}{x2 - x1}[/tex]

m =[tex]\frac{4 - (-2)}{(-9)-3}[/tex]

m= 6/-12

m= -0.5 or -1/2

Therefore, the answer is B.

Answer:

The measure of the indicated angles is 62°.

Reason: vertical angles

Given:

The point is rotated at 272 degrees clockwise.

To find:

The smallest positive counterclockwise rotation for the given clockwise rotation.

Step-by-step explanation:

Clockwise rotation = 272°

We need to subtract the given clockwise rotation from 360° to get the smallest positive counterclockwise rotation, because one complete circle is 360°.

Counterclockwise rotation = 360° - Clockwise rotation

                                            = 360° - 272°

                                            = 88°

Therefore, the smallest positive counterclockwise rotation is 88°.

Step-by-step explanation:

Answer:

y=10x+35

so for 4 yoga classes, it is $75

so for 8 yoga classes, it is $115

so for 12 yoga classes, it is $155

Step-by-step explanation:

So 35 is only a one-time payment and it is over so we just add 35, but $10 is the rate of change depending on how much yoga class you have been into so the equation will be y=10x+35

Explanation for 4 yoga classes: y=10(4)+35 which is 75

Explanation for 8 yoga classes: y=10(8)+35 which is 115

Explanation for 12 yoga classes: y=10(12)+35 which is 155

I think it might be C im not sure tho

Answer: c = 3

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

Step 1: Subtract 4 from both sides.

-17 - 4 = -7c

Step 2: Simplify -17 - 4 to -21.

-21 = 7c

Step 3: Divide both sides by -7.

[tex]\frac{-21}{-7}[/tex] = c

Step 4: Two negatives make a positive.

[tex]\frac{21}{7}[/tex] = c

Step 5: Simplify [tex]\frac{21}{7}[/tex] to 3.

3 = c

Step 6: Switch sides.

c = 3

Answer:

Step-by-step explanation:

Two lines are perpendicular to each other if they both intersects and the two lines are inclined at angle 90°

Since they are inclined at 90° to each other, hence they create right angles.

The lines can also lines on the same plane to form a right angles. This are called coplanar lines.

From the above explanation, the following are true;

I) Perpendicular lines intersect

II) Perpendicular lines create right angles

V) Perpendicular lines are coplanar

They are not collinear because they can't lie on the same straight line. Collinear lines are known to lie on the same straight line.

Answer:

NO

Step-by-step explanation:

if we plug in 1 = x, we get 4.75 = y. If this is proportional, then y/x will be the same in each scenario.

Let's plug in 2 = x to get y = 5.75. 5.75/2 = 2.875 DOES NOT EQUAL 4.75/1 = 4.75.

That means that the relationship is NOT proportional.

The easier way to tell is to see that there is a number being added, so it can't be a proportional relationship.

Hope this helps and pls do mark me brainliest if you can:)

Answer: No

Step-by-step explanation:

The equal y=x+3.75 is expressed in slope intercept form meaning it doesn't fit the proportional equation which is y=kx and k is the slope.

Because of the y-intercept of the line it makes it  not  proportional .

Answer: It's slope is zero

Answer:

5×5×5=5³

Step-by-step explanation:

Answer:

A power, or exponent, represents how many times the term, in this case 5, is multiplied by itself. So multiply 5 by itself until you get 125. Then write your answer as 5ˣ where x is the number of times you multiplied 5 by itself.
