Answer:

$151.20.

Step-by-step explanation:

35 % = 0.35  so we multiply the wholesale price by 1.35:

112 * 1.35

The marked-up price of the furniture will be $151.20.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that the wholesale price for a desk is $112. A certain furniture store marks up the wholesale price by 35%.

The mark-up price will be calculated as,

Mark up = (112 x 0.35) + 112

Mark up = 39.2 + 112

Mark up = $151.20

Therefore, the marked-up price of the furniture will be $151.20.

The equation to represent the function is f"(x) = (-1/ x + 3 )+ 8

The asymptotes is (x, y) = (-3, 8)

Given,

Let the reciprocal function be:

f(x) = 1/x

First, it was reflected across the x-axis.

The rule is: (x,-y)

So, we have:

f'(x) = -1/x

Next, translated 3 units left.

The rule is: (x, y) => (x + 3, y)

So:

f"(x) = -1/ x + 3

Lastly, translated 8 units up.

The rule is: (x, y) => (x, y + 8)

So:

f"(x) = -1/ x + 3 + 8

To get the vertical asymptote, we simply equate the denominator to 0.

i.e.

x + 3 = 0

x = -3

To get the horizontal asymptote, we simply equate y to the constant.

i.e.

y = 8

(x, y) = (-3, 8)

x is approximately equal to 3.2574.

To solve for x in the equation tan 74° = x/1.4, we can use trigonometric properties and algebraic manipulation.

Convert the angle measure to radians:

We know that 1 radian is approximately equal to 57.3 degrees. Therefore, we convert 74 degrees to radians:

74° * (π/180°) ≈ 1.2915 radians.

Rewrite the equation with the angle measure in radians:

tan(1.2915) = x/1.4.

Solve for x:

To isolate x, we can cross-multiply:

tan(1.2915) * 1.4 = x.

Use a calculator to find the tangent of 1.2915 radians:

tan(1.2915) ≈ 2.3274.

Multiply the tangent value by 1.4 to find the value of x:

2.3274 * 1.4 ≈ 3.2574.

Therefore, x is approximately equal to 3.2574.

In summary, by converting the angle to radians, calculating the tangent, and then multiplying by 1.4, we find that x is approximately 3.2574.

The sum of the residuals and what it tells us about the line of best fit is that: −1.06; This indicates that the line of best fit is not very accurate and is not a good model for prediction.

Mathematically, the residual value of a data set can be calculated by using this formula:

Residual value = actual value - predicted value

Next, we would determine the predicted values as follows:

At point (4, 6), we have;

Predicted value, y = 1.46x − 0.76.

Predicted value, y = 1.46(4) − 0.76.

Predicted value, y = 5.08

At point (6, 7), we have;

Predicted value, y = 1.46x − 0.76.

Predicted value, y = 1.46(6) − 0.76.

Predicted value, y = 8.

At point (7, 8), we have;

Predicted value, y = 1.46x − 0.76.

Predicted value, y = 1.46(7) − 0.76.

Predicted value, y = 9.46.

At point (9, 13), we have;

Predicted value, y = 1.46x − 0.76.

Predicted value, y = 1.46(9) − 0.76.

Predicted value, y = 12.38.

At point (10, 14), we have;

Predicted value, y = 1.46x − 0.76.

Predicted value, y = 1.46(10) − 0.76.

Predicted value, y = 13.84

At point (11, 15), we have;

Predicted value, y = 1.46x − 0.76.

Predicted value, y = 1.46(11) − 0.76.

Predicted value, y = 15.3.

Now, we can calculate the sum of the residuals as follows:

Sum of the residuals = Sum of actual values - Sum of predicted values

Sum of the residuals = (6 + 7 + 8 + 13 + 14 + 15) - (5.08 + 8 + 9.46 + 12.38 + 13.84 + 15.3)

Sum of the residuals = 63 - 64.06

Sum of the residuals = -1.06.

Answer: 13/25

Step-by-step explanation: it is equal to 52% which is greater than 50%

50% is greater than 13/25. To compare these two values, you can convert both of them to a common denominator, such as 50%. 50% is equal to 1/2, so 13/25 is equal to 52/50, which is less than 1/2 or 50%. Alternatively, you can also express both fractions as decimals and compare the two values that way. 50% is equal to 0.5, and 13/25 is equal to 0.52, so 50% is still greater than 13/25.

The relationship between the mean and median of the collected data is that the mean will be smaller than the median.

Since the SAT Math scores for these students will be mostly high scores, the distribution will be skewed to the left. Thus, the few low scores (outliers) will make the mean smaller than the median.

Outliers that do not change the mean have an impact just on the mean. As a result, the mean is frequently lower than that of the median when the distribution of data is skewed to the left. The mean is frequently higher than the median when the distribution is tilted toward the right. We anticipate that the mean and median in symmetrical distribution will be about identical in value. This is a crucial link between the connection here between mean and median as well as the distribution's form. Nevertheless, it isn't applicable to all sets of data. Collections of data sets are where exceptions happen much more frequently.

a = 1 and b = -7

Step-by-step explanation:

Given the expression

(3 + i)(1+2i)

On factorizing we have;

(3 + i)(1+2i)

= 3(1)+3(2i)+1(i)+i(2i)

= 3 + 6i + i + 2i²

= 3 + 7i + 2i²

Since i² = -1

The expression becomes;

= 3 + 7i + 2(-1)

= 3 + 7i -2

= 1 - 7i

On comparing with a + bi

a = 1 and b = -7

the null hypothesis for the given t-test\(`[h, p, 0] = ttest(morningsections, eveningsection)`\)

In the t-test formula for hypothesis testing, the null hypothesis states that there is no difference between the two groups being tested. Therefore, for the given t-test below:

`[h, p, 0] = ttest(morningsections, eveningsection)`,

the null hypothesis is that there is no significant difference between the average bedtimes of students in morning sections versus evening sections.

To explain further, a t-test is a type of statistical test used to determine if there is a significant difference between the means of two groups. The formula for a t-test takes into account the sample size, means, and standard deviations of the two groups being tested. It then calculates a t-score, which is compared to a critical value in order to determine if the difference between the two groups is statistically significant.

In this case, the two groups being tested are morning sections and evening sections, and the variable being measured is the average bedtime of students in each group. The null hypothesis assumes that there is no significant difference between the two groups, meaning that the average bedtime of students in morning sections is not significantly different from the average bedtime of students in evening sections.

The alternative hypothesis, in this case, would be that there is a significant difference between the two groups, meaning that the average bedtime of students in morning sections is significantly different from the average bedtime of students in evening sections. This would be reflected in the t-score obtained from the t-test, which would be compared to the critical value to determine if the null hypothesis can be rejected or not.

In conclusion, the null hypothesis for the given t-test\(`[h, p, 0] = ttest(morningsections, eveningsection)`\) is that there is no significant difference between the average bedtimes of students in morning sections versus evening sections.

Referring to the truth table, -P is false, and the only case with -P false is when both T and S are false.

This means that 5657 is not a triangular or square number.

(a) To create a truth table for the statement "If a number is triangular or square (T ∨ S), then it is not prime (-P)," we will have columns for T, S, T ∨ S, and -P.

Then we will consider all possible combinations of T and S (true and false) and fill out the remaining columns.
| T   | S   | T ∨ S | -P  |
|-----|-----|-------|-----|
| T   | T   | T     | T   |
| T   | F   | T     | T   |
| F   | T   | T     | T   |
| F   | F   | F     | F   |

(b) If the statement were false, a counterexample would need to have T ∨ S true, but -P false.

In other words, a number that is either triangular or square, and also prime. However, no such counterexample exists in the table, indicating that the statement is true.
(c) Since the statement is true, knowing that 5657 is prime (P) allows us to conclude that it is neither triangular (T) nor square (S).

Just took the test

Step-by-step explanation:

L = 1, the ratio test is inconclusive, and we cannot determine whether the series converges or diverges

The ratio test is a tool used to determine the convergence of an infinite series. Given a series Σ(an) from n=1 to infinity, the ratio test states that if the limit as n approaches infinity of |a(n+1)/an| equals L, then:
- If L < 1, the series converges
- If L > 1, the series diverges
- If L = 1, the test is inconclusive
Now let's apply the ratio test to the given series Σ(8n) from n=1 to infinity. To do this, we need to find the limit as n approaches infinity of |a(n+1)/an|:
|a(n+1)/an| = |8(n+1)/8n|
Simplifying the expression, we get:
|1 + 1/n|
As n approaches infinity, 1/n approaches 0, so the limit of the expression is:
|1 + 0| = 1
Since L = 1, the ratio test is inconclusive, and we cannot determine whether the series converges or diverges based solely on this test.

Step-by-step explanation:

1)  Total rectangle area =  W x H = 12 x 8 = 96 cm^2

 area of triangle (shaded portion) = 1/2 base * height = 1/2 * 7 x 8 = 28 cm^2

              Nonshaded portion = 96 - 28 cm^2 = 68 cm^2

          ratio shaded:nonshaded is then   28 : 68 = 7:17

2)   Look at the two middle triangles :  Height of each = 8 cm

       then reading across the diagram  height + base + height = 21 cm

            so base = 5 cm

   area of ONE triangle = 1/2 * base * height = 1/2 * 5 * 8 = 20 cm^2

        total area for FOUR of them  = 80 cm^2
