Step-by-step explanation:

The age is not a proportional relationship because it does not go through the point (0,0)

The hours is a proportional relationship.  It goes through the point (0,) and has a constant slope

Answer:

3. NO

4. YES

Step-by-step explanation:

A proportional relation is of the form:

y = kx

Note that the y-intercept has to be 0, and slope should be constant

First one (Height against age) is not proportional because the intercept is 30, not 0

Second one (Time against distance) is proportional because the slope is constant and the y-intercept is 0

Answer:

2 millimeters

Step-by-step explanation:

Ethan used the scale 1 millimeter : 5 meters.

This means that 1 millimeter in the drawing represents 5 meters in actual life.

The actual  length of the garage is 10 meters. Therefore:

5 meters = 1 millimeter

=> 10 meters = (10 * 1) / 5 = 2 millimeters

The garage is 2 millimeters long in the drawing.

Question:

Vincent bought a 25-pound bag of rice. He cooked 6.25 pounds of the rice. He stored the rest of the rice in [tex]3\frac{3}{4}[/tex] - pound portions. What is the maximum number of [tex]3\frac{3}{4}[/tex] - pound portions he stored?

Answer:

The maximum number of portion he stored is 5 portion

Step-by-step explanation:

Given

Size of Rice = 25 lb

Size of Cooked Rice = 6.25 lb

Portions saved = [tex]3\frac{3}{4}[/tex] lb

Required

Number of portion saved;

First, the size of rice after cooking needs to be calculated;

If 6.25lb of rice was cooked from a total of 25lb;

Then, the size of rice left is

[tex]Size = 25lb - 6.25lb[/tex]

[tex]Size = 18.75lb[/tex]

Now that we have the amount left after cooking; we can simply calculate the maximum number of portions;

This is calculated by dividing size of rice left by portions of saved rice;

i.e.

Maximum number of portion = Size of rice left / Portions of saved rice

Maximum number of portion = [tex]\frac{18.75lb}{3\frac{3}{4}lb}[/tex]

Convert  [tex]3\frac{3}{4}[/tex] to mixed fraction

Maximum number of portion = [tex]\frac{18.75lb}{\frac{15}{4}lb}[/tex]

Maximum number of portion = [tex]\frac{18.75}{\frac{15}{4}}[/tex]

Rewrite expression

Maximum number of portion = [tex]18.75 / \frac{15}{4}[/tex]

Change divide (/) sign to multiplication (*)

Maximum number of portion = [tex]18.75 * \frac{4}{15}[/tex]

Maximum number of portion = [tex]\frac{75}{15}[/tex]

Maximum number of portion = 5

Hence, the maximum number of portion he stored is 5 portions

Answer:

Probability that 24 or more of those drivers were involved in accidents is 0.15625.

Step-by-step explanation:

We are given that an insurance agent research suggested that first year drivers had roughly an 13% chance of being involved in an automobile accident while driving.

The insurance agent provided insurance to 152 first year drivers last year.

Let [tex]\hat p[/tex] = sample proportion of drivers who were involved in accidents

The z score probability distribution for sample proportion is given by;

                           Z  =  [tex]\frac{\hat p-p}{\sqrt\frac{\hat p(1-\hat p)}{n} {} }[/tex]  ~ N(0,1)

where, p = population proportion of first year drivers involved in an automobile accident while driving = 13%

           n = sample of first year drivers = 152

Now, probability that 24 or more of those drivers were involved in accidents is given by = P([tex]\hat p[/tex] [tex]\geq[/tex] [tex]\frac{24}{152}[/tex])

       P([tex]\hat p[/tex] [tex]\geq[/tex] 0.16) =  P( [tex]\frac{\hat p-p}{\sqrt\frac{\hat p(1-\hat p)}{n} {} }[/tex] [tex]\geq[/tex] [tex]\frac{0.16-0.13}{\sqrt\frac{0.16(1-0.16)}{152} {} }[/tex] ) = P(Z [tex]\geq[/tex] 1.01) = 1 - P(Z < 1.01)

                                                                      = 1 - 0.84375 = 0.15625

The above probability is calculated by looking at the value of x = 1.01 in the z table which has an area of 0.84375.

Hence, the required probability is 0.15625.

Step-by-step explanation:

use substitution method so it will now look like

8x + 5(-4x) = 24

8x + (-20x) = 24

-12x = 24 (divide both sides by 12)

-x = 2 (multiply both sides by negative 1)

x = -2

substitute to find y

y= -4(-2)

=8

Answer:

[tex]x=-2\\y=8[/tex]

Step-by-step explanation:

[tex]8x+5y=24\\y=-4x[/tex]

We already have y in terms of, so the easiest way to do is by plugging that value in the first equation.

[tex]8x+5y=24\\8x+5(-4x)=24\\8x-20x=24\\-12x=24\\x=\frac{24}{-12} \\x=-2[/tex]

After having found the value of x, replace it in the second equation to find y.

[tex]y=-4(-2)\\y=8[/tex]

The question is incomplete, here is the complete question.

Carmen used a random number generator to simulate a survey of how many children live in the households in her town. There are 1,346 unique addresses in her town with numbers ranging from zero to five children. The results of 50 randomly generated households are shown below. Children in 50 Households Number of Children Number of Households 0 5 1 11 2 13 3 10 4 9 5 2 Using a proportion, what can you infer about the number of households in her town that have more than three children?

A) About 242 households have more than three children.

B) About 269 households have more than three children.

C) About 296 households have more than three children.

D) About 565 households have more than three children.

Step-by-step explanation:

The given sample size is 50

The number of households with more than three children = 9+2

= 11

The proportion of household where more than three children are present is calculated by:

Household with a greater number of children/sample size

= 11/50

The original household size= 1,346

Therefore, the amount of household with children greater than 3 is:

= 1346×11/50

= 1346× 0.22

= 296.12

= 296

Thus, about 296 households have more than three children.

If you divide any number by zero, the answer will be zero.

Step-by-step explanation:

You can't divide by zero. If you divide an number by zero on a calculator, it will come out as 'undefined'.

All other statements are true.

An integer that is positive is greater than zero, and a integer that is negative is less than zero. 0 is equal to 0, so it is neither positive or negative.

The sum of a number and zero will be that number. You are technically adding nothing.

[tex]4+0=4[/tex]

The product of any number and zero is zero. This is the "Multiplication Property of Zero".

[tex]4*0=0[/tex]

"If you divide any number by zero, the answer will be zero." should be the correct answer.

"If you divide any number by zero, the answer will be zero." should be the correct answer.

Addition property of zero:

The addition property of zero says that a number does not change when adding or subtracting zero from that number.

Multiplication property of zero:

Talia is not correct. The lateral area has three faces, so the expression should be 3 (one-half (8) (6.9)).

Step-by-step explanation:

A triangular prism has four triangles, three at the sides and one at the base.

A congruent shape has the same feature (side dimensions and angles), therefore all three sides of the prism, and the basal triangle have the same area (since they are congruent).

The area of the base will be One-half (8) (6.9), therefore each of the three sides too will have that same area.

Lateral area means only the areas of the sides excluding the base, therefore, the lateral area will be 3 (one-half (8) (6.9))

The set up will form a right angled triangle. The distance that Laura let out her kite string will be the hypotenuse of the triangle, the angle that the kite makes with the ground will be the angle of elevation, facing the height of the kite.

The height of the kite H, will be the opposite side of the triangle since it is facing the angle directly.  based on the trig identity SOH;

sintheta = opposite/hyp

sin68° = H/60

H = 60sin68°

H = 55.6m

The height of the kite is 55.6m

Answer:

In this problem, I can not tell what is V, so I will answer it in a general way.

A polynomial is something of the form:

a*x^5 + b*x^4 + c*x^3 + d*x^2 + e*x + f

a, b, c, d, e, and f are real numbers and constant.

Where the degree of the polynomial is equal to the greatest power (in this case 5).

You write:

4x^2 + 3Vx + 5

Now, if V is a real number, then we have that this is a polynomial of degree 2.

Because we can write this as:

4*x^2 + (3V)*x + 5

So the answer is true.

Now, if V is a variable or an operation, the answer will be false.
