A
2 times a number decreased by 12

B
2 decreased by 12 times a number

C

Answer:

y=4x+2

Step-by-step explanation:

-8x+2y=4

y=4x+2

−8x+2(4x+2)=4-8x+2(4x+2)=4

y=4x+2

−8x+8x+4=4-8x+8x+4=4

y=4x+2

0+4=40+4=4

y=4x+2

4=4

y=4x+2

Answer:

B and C

Step-by-step explanation:

A general way to know this is, if the answer can be given as a rate, percentage, or probability, then this is a statistical question

If the answer is yes, no, true, false, or something exact, then the question is not statistical.

Let's analyze the given questions:

a) "How many cups are in a gallon?"

There is an exact number of cups in a gallon (16) so this is not an staistical question.

b) "Which measure spoon do home backers use most frequently?"

While here the answer may be something like "teaspoon", the root of the answer is a percentage, here we actually would see the percent of home backers (so we need to find a sample, study that sample, etc) that use each spoon, and based on that, we could conclude what is the correct answer, then this is a statistical question.

c) "On average, how much salt do professional pastry chefs use in pie crust?"

Here we need to find a mean value, so we would need to do a survey and etc, then this is a statistical question.

d) "Which is larger, 17 ounces or 2 cups?"

Here we have an exact solution, so this is not a statistical question.

e) "Did a specific store sell more measuring cups or measuring spoons on a given day?"

Here we just need to compare the two numbers:

number of measuring cups sold = k

number of measuring spoons sold = m

And we need to see which one is larger, so the answer is exact, thus, this is not a statistical question.

This may be similar to option B, the difference is that in option B we are talking about all home backers, so we need to find a sample and do statistics, while in this case, we are talking about a specific store.

Then the correct options are: B and C

Answer:

Neither game A or B is fair

Step-by-step explanation:

statement accurately describes whether these games are fair is neither game A nor game B.

Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

For, game A:

Not fair

For game B,

Again,  unfair.

P (odd, odd)= 1/4

P(even, even)=1/4

P(odd, even)=1/2

Hence, none of the game is fair.

Answer:

measure of 1 = 117 degrees

measure of 2 = 63 degrees

*x = 39

Step-by-step explanation:

m1 = 3 x 39 = 117

m2 = 39 + 24 = 63

117 + 63 = 180 degrees

m∠1 = 3x and m∠2 = x + 24

now,

m∠1 + m∠2 = 180° (angle made in straight line)

3x + x + 24 = 180°

4x = 180-24

4x = 156

x = 156/4

x = 39°

also, 3x = 3×39 = 117

x + 24 = 39 + 24 = 63

Answer:

117

Step-by-step explanation:

The figure is five sided, therefore the sum of the angles = (5-2)180

                                                                                             = 3*180

                                                                                             = 540

113 + 123+97+90(since its right angles)+y(unknown) = 540

423 + y = 540

y = 540 - 423

y = 117

Let the angle vertically opposite to y be z

y = z (vertically opposite angles)

z = 117

x = 117 (Corresponding angles are equal)

Answer:

x = -1

y = -1

Step-by-step explanation:

This is a system of equations- the set up of the problem lends well to using the elimination method. There are always many ways of solving a system of equations, both in methods and different strategies within each method. The problem isn't necessarily complete but I can assume you're being asked to solve for x and y values.

divide the first equation by -2. this means we can use elimination to cancel out the y value, and is also our simplest option (rather than multiplying the second equation by -2.

-2x + 20y = -18 --> x - 10y = 9

x - 10y = 9

8x + 10y = -18

Using the elimination method to essentially add the parts of the equations together, this comes out to 9x = -9 , meaning x = -1 .

We can then return to our original equations, and substitute -1 for x (either equation will work, but the second one is simpler and therefore the better option).

8 (-1) +10y = -18

-8 + 10y = -18

10y = -10

y = -1

CHECKING

Substitute both x and y values back into the original equations to check them. the sides should be equal if our values are correct.

-2 (-1) + 20 (-1) = -18

Our first equation works: 2 - 20 = -18

8 (-1) + 10 (-1) = -18

The second equation works as well: -8-10= -18

Answer:

C' = -10,2

D' = -1,6

E' = -10,2

Answer:

see explanation

Step-by-step explanation:

Under a reflection in the vertical line x = - 1 the y- coordinates remain unchanged.

The points and their images will be the same distance from x = - 1

The original points are to the left and the image points to the right.

C (- 10, - 6 ) is 9 units to the left of x = - 1 , then

C' (- 1 + 9, - 6 ) → C' (8, - 6 ) ← 9 units right

D (- 1, - 6 ) is on the line of reflection and remains unchanged

D (- 1, - 6 ) → D' (- 1, - 6 )

E (- 10, - 2 ) → E' (- 1 + 9, - 6 ) → E' (8, - 2 )

Then

C (- 10, - 6 ) → C' (8, - 6 )

D (- 1, - 6 ) → D' (- 1, - 6 )

E (- 10, - 2 ) → E' (8, - 2 )

$863

Step-by-step explanation:

Given: Carla Arslanian is 55 years old. She wants to purchase a $100,000, 10-year term life insurance policy.

To find: What is her annual premium?

Solution: Insurance companies use mathematical calculation and statistics to calculate the number of insurance premiums they charge their clients.

Annual premium = face value x rate $100

Annual premium (for building) = $100,000 ÷ $1000 x 10 = $1000.  

The sum of the annual premium is $863.

Answer:

<CPE= 137

Step-by-step explanation:

In order to find the measure of (<CPE), one must add the measure of <(CPD) and (<DPE). From the given picture, one can infer that line (CA) is a diameter. This means that the sum of all angles on either side of the line is (180). Therefore, to find the measure of (<DPE) add up all of the angle measures on one side of the line, and set it equal to (180). Solve and then add the result to the value of (<CPD) to find the measure of (<CPE).

(<CPD) + (<DPE) + (<EPA) = 180

Substitute,

88 + (<DPE) + 43 = 180

Simplify,

131 + (<DPE) = 180

Inverse operations,

<DPE = 49

Now add the value of (<DPE) to (<CPD),

(<CPD) + (<DPE)

= 88 + 49

= 137
