Step-by-step explanation:

The blueberry muffins made by baker on monday is 40% of the total muffins made by the baker .

A quantity or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. In order to determine the percentage of a number, divide it by its sum and then multiply the result by 100. The proportion thus refers to a component per 100. The word percent indicates a percentage of 100. The word "percent" denotes "per 100." The letter "%" stands for it.

Now in the given question,

Total number of muffins baker made = 90

Blueberry Muffins made by baker on monday = 36

Prcentage of blueberry muffins out of total muffins  \(=\frac{36*100}{90} = 40 %\)

So , the Blueberry Muffins were 40% of the total muffins baker made.

the ladder reaches about 18.75 feet up the side of the house.

we can use the Pythagorean theorem which states that in a right triangle, the sum of the squares of the two shorter sides (the legs) is equal to the square of the longest side (the hypotenuse). In this case, the ladder is the hypotenuse, and the distance from the house to the base of the ladder is one leg.
So, if we let x be the distance up the side of the house that the ladder reaches, then we can write:
\(x^{2}\) + \(7^{2}\) = \(20^{2}\)
Simplifying this equation, we get:
\(x^{2}\) + 49 = 400
Subtracting 49 from both sides, we get:
\(x^{2}\) = 351
Taking the square root of both sides, we get:

Step-by-step explanation:

8 is the slope and it is positive

Rise over run is Right 4 and down 1 so that is Plus 4 and negative 1

a) The x-intercepts of y=f(x) is (-3,0) (4,0)

b) The x-intercepts of y=-2f(x) is (-3,0) (4,0)

c) The x-intercepts of y=f(-1/2x) is (-1/8,0) (1/6,0)

d) The x-intercepts of y=f(-(x+1)) is (-5,0) (2,0)

A line's x-intercept is the distance in x coordinates from the line's intersection with the x-axis at its origin. A location on the graph where y is 0 is known as the x-intercept. The x-intercept of a line that is perpendicular to the y-axis is undefined.

Here to determine the x-intercept put y=0,

Given f(x)=(x-4) (x+3)

a) y=(x-4) (x+3)

Replacing y by 0 we get,

(x-4) (x+3) =0

x=-3, 4

Therefore, x-intercepts of y=f(x) is (-3,0) (4,0)

b) y = -2(x-4) (x+3)

Replacing y by 0 we get,

-2(x-4) (x+3) =0

x=-3, 4

Therefore, x-intercepts of y=-2f(x) is (-3,0) (4,0)

c) y= (-\(\frac{1}{2x}\)-4) (-\(\frac{1}{2x}\)+3)

Replacing y by 0 we get,

(-\(\frac{1}{2x}\)-4) (-\(\frac{1}{2x}\)+3) =0

By solving the above equation

(-\(\frac{1}{2x}\)-4) =0 and (-\(\frac{1}{2x}\)+3) =0

-1/2x=4 and -1/2x=-3

x=-1/8 and x=1/6

Therefore, x-intercepts of y=f(-1/2x) is (-1/8,0) (1/6,0)

d) y=(-(x+1)-4) (-(x+1) +3)

Replacing y by 0 we get,

(-(x+1)-4) (-(x+1) +3) =0

By solving the above equation

(-(x+1)-4) =0 and (-(x+1) +3) =0

-(x+1) =4 and -(x+1) =-3

x=-5, 2

Therefore, x-intercepts of y=f(-(x+1)) is (-5,0) (2,0)

Answer:

If we denote the width of the enclosure as W (in inches), then according to the description:

- The length L is W + 20 inches.

- The height H is 2W + 5 inches.

The volume V of a rectangular enclosure is given by the formula V = LWH.

Substituting L and H into the volume formula, we have:

V = (W + 20)(W)(2W + 5).

Simplifying this expression, we get:

V = 2W^3 + 45W^2 + 100W.

So, the volume of the enclosure in cubic inches is given by the polynomial expression 2W^3 + 45W^2 + 100W. If we compare this with a generic cubic polynomial AW^3 + BW^2 + CW, then A = 2, B = 45, and C = 100. Note that we don't have a constant term, so D = 0.

Answer:

\( \frac{x}{4} + \frac{1}{2} = \frac{1}{8} \)

\( \frac{x}{4} = - \frac{3}{8} \)

\(x = - \frac{3}{2} = - 1 \frac{1}{2} \)

The solution to the equation x/4 + 1/2 = 1/8 is x = -3/2.

Consider the equation, we have only one x term, so taking all the terms without x to the other side and terms with x on one side.

x/4 + 1/2 = 1/8

Take the 1/2 term on the other side,

x/4=1/8 - 1/2

Taking the LCM on the Right side,

x/4 = (1-4) / 8

x/4 = -3/8

Now, we have x/4 so what we can do is, shift the 4 to the other side too, we get,

x = ( -3/8) * 4

x = -3/2

The solution to the equation x/4 + 1/2 = 1/8 is x = -3/2.

Based on the SAS similarity theorem, the right option is: C) ΔVML ∼ ΔUMT.

In order to determine if two triangles are similar, find out if the ratio fo their corresponding side lengths are equal, that is, their lengths must be proportional to each other if they are similar triangles.

The SAS states that if two pairs of sides of two triangles are proportional to each other, and they have a pair of corresponding congruent included angles, then they are similar triangles.

Given the image showing the two triangles, we have the following measures:

VM = 14, which is corresponding to UM = 49

LM = 8, which is corresponding to TM = 28

VM/UM = 14/49 = 2/7

LM/TM = 8/28 = 2/7

This means the two sides are proportional.

Also, angles VML and UMT are congruent to each other based on the vertical angles theorem.

Therefore, we can state that the ΔVML ∼ ΔUMT by SAS. The right option is C.

The probability of getting a z-score greater than 0.15 is approximately 0.5693.

The probability of getting more than 2100 nails in a bag is approximately 0.5693.

The number of nails in a bag is a discrete random variable, so it's not appropriate to use a normal distribution to model it.

Also, the mean of 8.9 and standard deviation of 5.56 are for a single nail, not for a bag of 225 nails.

To answer the question, we need more information on the distribution of the number of nails in a bag.

Assuming that the distribution is approximately normal, the mean of the number of nails in a bag would be 225 * 8.9 = 2009 and the standard deviation would be the square root of 225 * (5.56)^2 = 59.11.

With these values, we can use a standard normal distribution to find the probability of getting more than 2100 nails in a bag:

z = (2100 - 2009) / 59.11 = 0.15

Note: This calculation assumes that the distribution is approximately normal, and that the mean and standard deviation of a single nail are accurate. These assumptions might not hold in practice, so the answer should be taken with caution.

(a) The percentage of students that had a score over 90 was approximately 90.88%. (b) The cut-off score for F is 37 or lower.

(a) To find the percentage of students that had a score over 90, we can use the properties of the normal distribution.

First, we need to calculate the z-score corresponding to a score of 90:

z = (90 - 70) / 15 ≈ 1.33

Next, we can use the standard normal distribution table or a calculator to find the percentage of students with a score greater than 90. Looking up the z-score of 1.33 in the table, we find that the corresponding area is approximately 0.9088.

Converting this to a percentage, we get:

Percentage = 0.9088 * 100 ≈ 90.88%

Therefore, the percentage of students that had a score over 90 is approximately 90.88%.

(b) To determine the cut-off score for F, we need to find the score below which the lower 2% of all scores fall.

First, we need to calculate the z-score corresponding to the lower 2%:

z = -2.05 (approximately, obtained from the standard normal distribution table)

Next, we can use the z-score formula to find the corresponding score:

x = z * standard deviation + mean

x = -2.05 * 15 + 70 ≈ 36.75

Since scores are typically whole numbers, we round the cut-off score for F to the nearest integer, which is 37.

Therefore, students getting the score 37 or lower will receive an F.
