A significance level of 0.10, we have enough evidence to conclude that the new copy machines have a significantly faster mean repair time compared to the older model.

To test if the new copy machines are faster to repair, we can set up the following null and alternative hypotheses:

Null Hypothesis (H₀): The mean repair time for the new copy machines is the same as the mean repair time for the older model.

Alternative Hypothesis (H₁): The mean repair time for the new copy machines is less than the mean repair time for the older model.

Let's perform a one-sample t-test to test these hypotheses. The test statistic is calculated as:

t = (sample mean - population mean) / (sample standard deviation / √(sample size))

Given:

Population mean (μ) = 93 minutes

Sample mean (\(\bar x\)) = 86.8 minutes

Sample standard deviation (s) = 14.6 minutes

Sample size (n) = 18

Significance level (α) = 0.10

Calculating the test statistic:

t = (86.8 - 93) / (14.6 / sqrt(18))

t = -6.2 / (14.6 / 4.24264)

t ≈ -2.677

The degrees of freedom for this test is n - 1 = 18 - 1 = 17.

Now, we need to determine the critical value for the t-distribution with 17 degrees of freedom and a one-tailed test at a significance level of 0.10. Consulting a t-table or using statistical software, the critical value is approximately -1.333.

Since the test statistic (t = -2.677) is less than the critical value (-1.333), we reject the null hypothesis.

Each portion will be 1/8 of the whole stick of butter.

We will use the concept of fraction to find the amount of portion of the whole stick of butter.

The available part of stick of butter = 1/2

When it is divided in four parts, we will divide the available amount with four to find the portion of the whole stick of butter.

Portion size = (1/2)/4

Performing the division of fractions

Portion size = 1/(2×4)

Performing multiplication in denominator on Right and Side of the equation

Portion size = 1/8

Events, of randomly drawing a King OR a card with an even number describe by a) Mutually Exclusive.

The events of randomly drawing a King and drawing a card with an even number are mutually exclusive. This means that the two events cannot occur at the same time.

In a standard deck of 52 playing cards, there are no Kings that have an even number.

Therefore, if you draw a King, you cannot draw a card with an even number, and vice versa.

The occurrence of one event excludes the possibility of the other event happening.

It is important to note that mutually exclusive events cannot be both independent and conditional. If two events are mutually exclusive, they cannot occur together, making them dependent on each other in terms of their outcomes.

The original ticket price for a play is $50 per person. On Monday afternoons, the theater reduces the ticket price to $35 per person. This means there is a discount of:

\(\text{Discount = Original price - Reduced price}\)

\(\text{Discount} = \$50 - \$35\)

\(\text{Discount} = \$15\)

Therefore, the discount for a regular ticket to a Monday afternoon performance is $15 per person.

Now, students receive an additional $5 discount on all tickets. This means the total discount for a student ticket to a Monday afternoon performance is:

\(\text{Total Discount = Regular Discount + Student Discount}\)

\(\text{Total Discount} = \$15 + \$5\)

\(\text{Total Discount} = \$20\)

To calculate the percentage discount for a student ticket, we need to divide the total discount by the original ticket price and then multiply by 100:

\(\text{Percentage Discount} = \dfrac{\text{Total Discount}}{\text{Original Price}} ) \times 100\%\)

\(\text{Percentage Discount} = (\dfrac{\$20}{\$50} ) \times 100\%\)

\(\text{Percentage Discount} = 40\%\)

Therefore, the percentage discount for a student ticket to a Monday afternoon performance is 40%.

Given:

Bases of the trapezoid are 5.2 m and 14.6 m.

The height of the trapezoid is 7 m.

To find:

The area of the trapezoid.

Solution:

The area of a trapezoid is:

\(A=\dfrac{a+b}{2}\times h\)

Where, a,b are bases and h is the height of the trapezoid.

Putting \(a=5.2,b=14.6,h=7\) in the above formula, we get

\(A=\dfrac{5.2+14.6}{2}\times 7\)

\(A=\dfrac{19.8}{2}\times 7\)

\(A=9.9\times 7\)

\(A=69.3\)

Therefore, the area of the trapezoid is 69.3 square meters.

The measure of the missing side lengths of the triangle is adjacent side = 5 and hypotenuse =  5√2.

What are trigonometric ratios?

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle.

To find the side of a right triangle:

A right-angle triangle has one of its angles as 90 degrees.

Therefore,

using trigonometric ratios,

tan 45 = opposite/adjacent

tan 45 = opposite / 5

opposite side = (tan 45)  * 5

opposite side = 1 * 5 = 5

Therefore,

adjacent side = 5

sin 45 = opposite / hypotenuse

1/√2  = 5 / hypotenuse

hypotenuse = 5√2 /1

hypotenuse =  5√2

Hence, the missing side lengths of the triangle are adjacent side = 5 and hypotenuse =  5√2.

A. The factored form of f(x) is (4x - 4)(-4x + 1).

B. The x-intercepts of the graph of f(x) are -1/4 and 4.

C The end behavior of the graph of f(x) is that it approaches negative infinity on both ends.

A. To factor the quadratic function f(x) = -16x² + 60x + 16, we can rewrite it as follows:

f(x) = -16x² + 60x + 16

First, we find the product of the leading coefficient (a) and the constant term (c):

a * c = -16 * 1 = -16

The numbers that satisfy this condition are 4 and -4:

4 * -4 = -16

4 + (-4) = 0

Now we can rewrite the middle term of the quadratic using these two numbers:

f(x) = -16x² + 4x - 4x + 16

Next, we group the terms and factor by grouping:

f(x) = (−16x² + 4x) + (−4x + 16)

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

Now we can factor out the common binomial (-4x + 1):

f(x) = (4x - 4)(-4x + 1)

So, the factored form of f(x) is (4x - 4)(-4x + 1).

Part B: To find the x-intercepts of the graph of f(x), we set f(x) equal to zero and solve for x:

f(x) = -16x² + 60x + 16

Setting f(x) = 0:

-16x² + 60x + 16 = 0

Now we can use the quadratic formula to solve for x:

x = (-b ± √(b² - 4ac)) / (2a)

In this case, a = -16, b = 60, and c = 16. Plugging in these values:

x = (-60 ± √(60² - 4(-16)(16))) / (2(-16))

Simplifying further:

x = (-60 ± √(3600 + 1024)) / (-32)

x = (-60 ± √(4624)) / (-32)

x = (-60 ± 68) / (-32)

This gives us two solutions:

x1 = (-60 + 68) / (-32) = 8 / (-32) = -1/4

x2 = (-60 - 68) / (-32) = -128 / (-32) = 4

Therefore, the x-intercepts of the graph of f(x) are -1/4 and 4.

Part C: As x approaches positive infinity, the term -16x² becomes increasingly negative since the coefficient -16 is negative. Therefore, the end behavior of the graph is that it approaches negative infinity.

Similarly, as x approaches negative infinity, the term -16x² also becomes increasingly negative, resulting in the graph approaching negative infinity.

Hence, the end behavior of the graph of f(x) is that it approaches negative infinity on both ends.
