Step-by-step explanation:

I don't see really the actual answer options (you made a bad copy here).

so, I can only tell you what it is in my own terms and you need to associate to the actual answer option.

based on real numbers (not complex or imaginary) we cannot use the square root function on negative numbers.

the domain defined what values can be used for x.

so,

Answer:

y = -120

Step-by-step explanation:

Direct variation is

y = kx where k is a constant

9 = k(-3)

Divide each side by -3

9/-3 = k

-3 = k

y = -3x

Let x = 40

y = -3(40)

y = -120

As she eats granola for almost everyday as breakfast C. buying pack of five will be mot cost effective.

Buying a product in large amount costs less per unit as we buy more units so it make up the income percent per unit on amount of unit.

According to the give question Nancy wants to some granola which she eats for breakfast for almost everyday we have to determine which will be most cost effective.

As she eats this for almost everyday she must but the most amount she can as there is transportation cost to go to the mall everyday and it is also time consuming and also buying a certain thing in large possible amount costs less per unit.

Answer:

for the lengths, just double the numbrrs

1.5 -> 3

2.5 -> 5

bc the scale factor is two (the upper edge is given)

the angles are just the same, no matter the zoom factor

There are two polygons where B is greater than A.

One side in polygon A has a length of 2.5 and the corresponding length in polygon B is 5.

So, the scale factor is

[tex]\dfrac{5}{2.5}=2[/tex]

So, the missing sides in polygon B are

[tex]1.5\times2=3[/tex]

[tex]2.5\times 2=5[/tex]

The angles in polygon A will be the same as B as all the sides of the polygon have changed according to the scale factor.

So, the missing sides in polygon B are 3 and 5, and the angles in polygon A are [tex]53^{\circ}[/tex] and [tex]82^{\circ}[/tex].

Step-by-step explanation:

=========================================================

Explanation:

Rule: if |x| > k, then x < -k or x > k

Using that rule for the given inequality means we have these steps

|x-4| > 3

x-4 < -3  or x-4 > 3

x < -3+4 or x > 3+4

x < 1  or  x > 7 ..... choice E

-------------

Here's a visual way to see why this is the case.

|x-4| represents the distance from x to 4 on the number line.

When we say |x-4| > 3, we want to know which points are more than 3 units away from 4 on the number line.

We can plot 4 on the number line, and then measure 3 units below it (to get to 1) and then 3 units above it (to get to 7). If we're in the region 1 < x < 7, then we're within 3 units of 4 on the number line. Otherwise, we're more than 3 units away from the target we're after.

Answer:

−0.2542372881

Answer:

length = 12

width = 15

Step-by-step explanation:

if you foil (x+7)(x+10) you get:

x²+17x-110 = 0

the factors are:

(x+22)(x-5) = 0

x = -22 and 5

we can dismiss the negative as irrelevant for a measure; therefore, x = 5

length = 5+7, or 12

width = 5+10, or 15

Answer:

c. normal probability distribution

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

In this question:

By the Central Limit Theorem, it is a normal distribution, so option c.

m = -3

Step-by-step explanation:

Two poin on this line are (-2, 3) and (0, -3).  Both points are formed where grid lines meet precisely.

The change in x as we go from (-2, 3) to (0, -3) is +2 and the change in y is -6.  Thus, the slope of the line shown is m = rise/run = -6/2, or m = -3.

Answer:

C

625

Step-by-step explanation:

We must first find the length of the side

So remember that the area of a square is side squared

So to find the length of the side we square root A

Since the perimeter of a square is 4 times the side we end up with 4square root(A)

And the whole thing must equal less than 100

So its C

Answer:

0.5185 kg are needed to make 2 kg of cat food

Step-by-step explanation:

Chicken bones and chicken pieces in the ratio 20:7

This means that [tex]\frac{20}{20 + 7} = \frac{20}{27}[/tex] of the total weight is of bones and [tex]\frac{7}{27}[/tex] is of pieces.

What weight of chicken pieces is needed to make 2 kg of cat food?

7/27 of 2kg. So

(7/27)*2 = 14/27 = 0.5185 kg

0.5185 kg are needed to make 2 kg of cat food

Answer:

Angle 2 = 124 degrees

Step-by-step explanation:

Angles 1 and 2 are corresponding angles since the two lines are parallel.

We can put both numbers into an equation.

3x + 25 = 2x + 58

Subtract both sides by 2x which will give:

x + 25 = 58

Now, we can solve for x, which is:

x = 58-25 = 33

Put back x = 33 into angle 2.

Hence, angle 2 is 2*33 + 58 = 124

Answer:

m∠2 = 124 degrees

Step-by-step explanation:

By the definition of "Same Side Corresponding Angles" the 2 angles given are congruent to each other, therefore we can say;

3x + 25 = 2x + 58

x + 25 = 58

x = 58 - 25

x = 33

Now that we have x = 33, we can substitute 33 in for x, in equation given for angle 2 to find it's measure;

∠2 = 2(33) + 58

∠2 = 66 + 58

∠2 = 124

Therefore m∠2 = 124 degrees.

Answer:

The discount was A) $ 24.51 and B) 14.5% of the value.

Step-by-step explanation:

Since a department store offered a 10% discount on all humidifiers, and they also stated that the first 50 customers would receive an additional 5% discount off the sale price, if I purchase a humidifier that sells for $ 169 and I are among the first 50 customers, to determine what will my total discount be (a) in dollar amount and (b) in percent, the following calculation must be performed:

100 - 10 = 90

100 - 5 = 95

(169 x 0.9) x 0.95 = X

152.1 x 0.95 = X

144.49 = X

169 = 100

144.49 = X

144.49 x 100/169 = X

85.5 = X

Therefore, the discount was A) $ 24.51 and B) 14.5% of the value.
