Answer:

Charles is incorrect

Step-by-step explanation:

Lupe bought 8 pounds of pretzels for $18, meaning that she bought them at a unit rate of $2.25 per pound. Charles bough 6 pounds of pretzels for $15, meaning he bought them at a unit rate of $2.50 per pound. Even though Charles paid less, he didn't get the better deal because he paid more per pound than Lupe did.

The probability that the 4 samples contain at least 3 yellow apples is 52.5%.

Probability refers to the ratio or measure of the likelihood of an event occurring given many possible outcomes.

Probability is depicted in decimals, fractions, or percentages.

The number of red apples in the basket = 6

The number of yellow apples in the basket = 14

Total number of apples in the basket = 20

The probability of a yellow apple = 0.70 (14/20)

Sample size = 4 apples

The number of at least yellow apples = 3

The probability of yellow apples picked in the sample = 0.75 (3/4)

The probability that the 4 samples contain at least 3 yellow apples = 0.525 (0.70 x 0.75)

= 52.5%

Thus, the probability is 52.5%.

The given statement is true.

The equation that represents number of hours "h" which Ezekiel spend doing "math-homework" during the next 5 days is (d) h = 5t/4.

If Ezekiel spends 1/4 of his time on math homework, then he spends 3/4 of his time on other subjects. This means that out of every 4 hours he spends on homework, he spends 1 hour on math and 3 hours on other subjects.

So, in "t" hours, he will spend "t/4" hours on math homework.

To find the number of hours he will spend on math homework during the next 5 days, we multiply the time he spends on math homework in one day by the number of days.

⇒ Number of hours spent on math homework in 1 day = t/4,

⇒ Number of hours spent on math homework in 5 days = 5 × (t/4) = 5t/4,

The required equation is h = 5t/4,

Therefore, the correct option is (d).

Answer:

The table represents a nonlinear function because the rate is not constant.

Step-by-step explanation:

As shown in the picture below, the x side of the table has the same rate of change of +1. However, due to the fact that the y side does not have the same rate of change, +6 and +3, the table represents a non linear function. If the rate on the y side of the table were all the same, then this would be a Linear function.

9. The dilation of the larger solid figure on the coordinate grid to obtain the dashed figure can be represented by the expression in option C

C. (x, y), (-5/8·x, 5/8·y)

A dilation transformation is one in which the dimensions of the sides of the pre-image are increased (enlarged) or decreased to get the image.

9. The dilation of a function, f(x), by a factor k are; f(k·x), and k·f(x), where;

f(k·x) is an horizontal dilation, and k·f(x) is a vertical dilation

The ordered pair (x, y) which can be expressed as (x, f(x)), where, y = f(x), following a dilation by a factor of k is therefore;

\((x, \, y) \overset{D_k}\rightarrow (k\cdot x, \ k\cdot f(x)) = (k\cdot x, \ k\cdot y)\)

The representation of a dilation of a point (x, y), by a factor of k is therefore, obtained by multiplying both the x and y-values by the factor k, as follows;

(x, y)   \(\overset{D_x} \rightarrow\)   (k·x, k·y)

Similarly, the representation of the reflection of the point (x, y) across the y-axis is the point (-x, y)

The point (-5.8·x, 5/8·y),m is therefore obtained from the dilation of the point (x, y), by a factor of 5/8, followed by a reflection across the y-axis.

The option that represents the dilation is therefore, option C

C. (x, y), (-5/8·x, 5/8·y)

Lee's TV costs $4.05 to operate for a month of 30 days.

To calculate the cost of operating Lee's TV for a month, we need to find out the total number of kilowatt-hours (kWh) of electricity consumed by the TV during that time.

First, let's find out how many watts Lee's TV consumes in a day:

250 watts/hour x 3 hours/day = 750 watts/day

To convert this to kilowatts, we divide by 1000:

750 watts/day ÷ 1000 = 0.75 kilowatts/day

Now, we can calculate the total number of kilowatt-hours consumed by the TV in a month:

0.75 kilowatts/day x 30 days = 22.5 kilowatt-hours

Finally, we can calculate the cost of operating the TV for a month:

22.5 kilowatt-hours x 18 cents/kilowatt-hour = $4.05

Answer:

(3x - 2)

(3x - 1)

Explanation:

The initial expression is:

18x² - 18x + 4

First, all coefficients are even numbers, so we can factorize the expression as;

2(9x² - 9x + 2)

Now, we can rewrite the expression inside the parenthesis as:

2((3x)² - 3(3x) + 2)

So, we need to find two numbers that multiply to 2 and add to -3. These numbers are -2 and -1, so:

2(3x - 2)(3x - 1)

Therefore the answers are:

2

(3x - 2)

The probability of an interception or fumble is 1/4.

The probability of an interception or fumble is 1/4. This is because the chances of an interception and fumble are mutually exclusive, meaning that they cannot both occur at the same time. Therefore, the probability of an interception or fumble is the sum of the probabilities for an interception (1/8) and a fumble (1/8), which is 1/4.

Probability of interception = 1/8

Probability of Fumble = 1/8

Probability of interception or fumble = 1/8 + 1/8 = 1/4

Answer:

Grogg's dad is 22

Step-by-step explanation:

Let D = dad's current age

Let g = Grogg's current age

6(d - 7) = g - 7 → 6d - 42 = g - 7 → 6d -35 = g

4(d - 3) = g - 3 → 4d -12 = g - 3 → 4d -9 = g

Set the two equations equal to each other and solve for d

6d - 35 = 4d - 9  Subtract 4d from both sides

2d -35 = -9  Add 35 to both sides

2d = 44  Divide both sides by 2

d = 22

Helping in the name of Jesus.

Answer:

Step-by-step explanation:

d = current dad age

g = current grogg age

d-7 = 6(g-7)

d-3 = 4(g-3)

Let's solve the first equation first:

Add 7 to both sides: d - 7 +7 = 6g - 42 + 7 so d = 6g - 35

Substitude d = 6g - 35 for d in d - 3 = 4g - 12

(6g-35)-3 = 4g-12 = 6g-38 = 4g-12

Subtract 4g from both sides: 2g - 38 = -12

Add 38 to both sides: 2g = 26

Easy: g = 13

And now substitude g in for any equations.

d-3 = 52-12

d = 43

The ordered pairs (-1, -6), (2, -18), (0, 0), and (-4, -12) do not correspond to the intervals where the graph of f(x) is decreasing. The pairs (1, -2) and (-3, -18) are the correct ones.

To determine where the graph of f(x) is decreasing, we need to examine the intervals where the function's derivative is negative. The derivative of f(x) is given by f'(x) = -3x^2 - 8x + 3.

Now, let's evaluate f'(x) for each of the given x-values:

f'(-1) = -3(-1)^2 - 8(-1) + 3 = -3 + 8 + 3 = 8

f'(2) = -3(2)^2 - 8(2) + 3 = -12 - 16 + 3 = -25

f'(0) = -3(0)^2 - 8(0) + 3 = 3

f'(1) = -3(1)^2 - 8(1) + 3 = -3 - 8 + 3 = -8

f'(-3) = -3(-3)^2 - 8(-3) + 3 = -27 + 24 + 3 = 0

f'(-4) = -3(-4)^2 - 8(-4) + 3 = -48 + 32 + 3 = -13

From the values above, we can determine the intervals where f(x) is decreasing:

f(x) is decreasing for x in the interval (-∞, -3).

f(x) is decreasing for x in the interval (1, 2).

Now let's check the ordered pairs in the table:

(-1, -6): Not in a decreasing interval.

(2, -18): Not in a decreasing interval.

(0, 0): Not in a decreasing interval.

(1, -2): In a decreasing interval.

(-3, -18): In a decreasing interval.

(-4, -12): Not in a decreasing interval.

Therefore, the ordered pairs (-1, -6), (2, -18), (0, 0), and (-4, -12) are not located in the intervals where the graph of f(x) is decreasing. The correct answer is: (1, -2), (-3, -18).

Answer:

y = -2/3 x - 13/3

Step-by-step explanation:

y = -2/3 x + 3/2

y = mx + b

m = -2/3

The slope of the given line is -2/3. Parallel lines have equal slopes, so our line also has slope -2/3.

m = -2/3

y = mx + b

y = -2/3 x + b

Substitute the given point for x and y and solve for b.

-7 = -2/3 (4) + b

-21/3 = -8/3 + b

b = -13/3

Answer: y = -2/3 x - 13/3
