Answer:

f(− 3) = 84

Step-by-step explanation:

Given the function,  f(x) = 7(9 − x), to find the value of f(-3) substitute x = -3 into the function:

f(− 3) = 7(9 − (− 3))

f(− 3) = 7(9 + 3)

f(− 3) = 7(12)

f(− 3) = 84

Therefore, f(− 3) = 84.

Answer:

Bailey earned approximately $499.99 on Thursday, including his commission

Step-by-step explanation:

Bailey's earnings on Thursday consist of his base pay plus his commission. His base pay is $90, and his commission is 11% of his sales.

Let's call Bailey's sales on Thursday "S". Then his commission is 0.11S.

We know that Bailey's total earnings on Thursday were $500. So we can write an equation:

$90 + 0.11S = 500$

To solve for S, we can subtract $90$ from both sides of the equation:

$0.11S = 410$

Then we can divide both sides by $0.11$:

$S = 3,727.27$

So Bailey's sales on Thursday were $3,727.27.

To find Bailey's total earnings, we can add his base pay and commission:

$90 + 0.11(3,727.27) \approx 499.99$

So Bailey earned approximately $499.99 on Thursday, including his commission.

Answer:

\(\chi^2 =\frac{60-1}{64} 36 =33.19\)

The degrees of freedom are:

\(df= n-1= 60-1= 59\)

And the p value would be given by:

\(p_v =2*P(\chi^2 >33.19)=0.0053\)

Since the p value is lower than the significance level we have enough evidence to reject the null hypothesis and we can conclude that the true deviation is different from 8 days.

Step-by-step explanation:

Data given

\(n=60\) represent the sample size

\(\alpha=0.01\) represent the confidence level  

\(s^2 =6^2 =36 \) represent the sample variance obtained

\(\sigma^2_0 =8^=64\) represent the value that we want to test

Hypothesis to test

We want to verify if the true deviation is equal to 8 days o not, so the system of hypothesis would be:

Null Hypothesis: \(\sigma^2 = 64\)

Alternative hypothesis: \(\sigma^2 \neq 64\)

The statistic is given by:

\(\chi^2 =\frac{n-1}{\sigma^2_0} s^2\)

Replacing we got:

\(\chi^2 =\frac{60-1}{64} 36 =33.19\)

The degrees of freedom are:

\(df= n-1= 60-1= 59\)

And the p value would be given by:

\(p_v =2*P(\chi^2 >33.19)=0.0053\)

Since the p value is lower than the significance level we have enough evidence to reject the null hypothesis and we can conclude that the true deviation is different from 8 days.

Answer: 6 feet long

Step-by-step explanation:

1ft. = 12 in

62 inches = 5 feet and 2 inches

Break down 62 into 60 and 2

60 divided by 12 = 5 (12x5=60)

60in. = 5ft.

2in. = 2in.

5ft. and 2in.

10in.= 10in.

Add the inches

10in. + 2 in. = 12 in.

12in.= 1ft.

5ft. + 1ft. = 6ft.

Answer: Nancy’s rope is 6ft. long

Answer:A unique line is defined by any two distinct (not identical) points. You have two distinct, which means you have a line. To find the equation for the line, we start with the slope-intercept equation for a line. This is only a template for a generic line, so we will have to find the specific values of m (slope) and b (y-intercept) that define your line.

The template: y = mx + b

b is the y-intercept, which, if you look at (0,–2), you will see is –2; it is where the line crosses the y-axis. Fill that value of b into our template to get:

y = mx – 2

Now, we only need the value of m, which is the slope. If you have two points on a line, you can calculate the slope of that line. The slope is the change (difference) of y over the change in x (difference) of x for two given points on the line. It's a fraction or ratio though sometimes it can be reduced to an integer.

So, taking your two points, you calculate the slope, m, in the following way:

(x1,y1) = (0,–2)

(x2,y2) = (5,1)

        y2 – y1                   1 – (–2)                1 + 2               3

m = ________   =     ________    =     ________  =    ____

       x2 – x1                      5 — 0

With the added parentheses, the expression simplified to 212.5.

PEMDAS is an acronym used to mention the order of operations to be followed while solving expressions having multiple operations. PEMDAS stands for P- Parentheses, E- Exponents, M- Multiplication, D- Division, A- Addition, and S- Subtraction.

To simplify the expression 30·5·7-3+2 and ensure that the order of operations is clear, we can place parentheses around the first two terms:

That is, (30.5·7)-3+2

= 213.5-3+2

Then, we can simplify by performing the addition and subtraction:

212.5

Therefore, with the added parentheses, the expression simplified to 212.5.

We know that the shape is an right triangle because the shape has two same length and two same angles. Therefore, we can use Pythagoras theorem to solve for x.

Therefore, the answer is x = 21.21.

Hoped this helped.

In this triangle, the product of sin B and tan C is\(b^2/(ac)\)  , and the product of sin C and tan B is \(c^2/(ab)\).

In a right-angled triangle ABC, where angle A is 90 degrees, we have the following side lengths:

AB = c (base)

BC = a (hypotenuse)

AC = b (perpendicular)

We need to calculate the products of sin B and tan C, and sin C and tan B.

First, let's calculate sin B and tan C:

sin(B) = opposite/hypotenuse = AC/BC = b/a

tan(C) = opposite/adjacent = AC/AB = b/c

The product of sin B and tan C is sin(B) * tan(C) = (b/a) * (b/c) = \(b^2\)/(ac).

Next, let's calculate sin C and tan B:

sin(C) = opposite/hypotenuse = AB/BC = c/a

tan(B) = opposite/adjacent = AB/AC = c/b

The product of sin C and tan B is sin(C) * tan(B) = (c/a) * (c/b) = \(c^2\)/(ab).

Therefore, in the given right-angled triangle ABC, the product of sin B and tan C is\(b^2\)/(ac), and the product of sin C and tan B is \(c^2\)/(ab).

These formulas hold true for any right-angled triangle, where the base is AB, the hypotenuse is BC, and the perpendicular is AC.

The selling price of the antique through an online auction website is $680.

Given that,

Kyle sold an antique through an online auction website.

The website host charges Kyle $15, plus 2.5% of the final selling price of the antique.

After selling the antique, Kyle had to pay the website host $32.

Let x be the selling price of the antique.

We get an equation,

15 + (2.5% × x) = 32

15 + 0.025x = 32

0.025x = 17

x = $680

Hence the selling price is $680.

Numbers and their variants, equations & related structures, and geometry and their regions and potential applications are all mathematical topics. The link between a group of input, each of which generates a related output, is referred to as a "function." A function is a relationship between outputs and inputs where each input results in a single, distinct output. Each procedure has a domain and a city / municipality, which are frequently referred to as a scope. Functions are usually represented by the letter f. (x). The input is X. On activity, one-to-one activities, many-to-one activities, throughout operations, as well as on functions are the four main categories of supplied functions.

Here,

There are no limitations on the type of rational function, therefore it is feasible to construct one with each of the three asymptotes.

This is depicted in the attached graph, along with the graph of the rational function it represents. These are the asymptotes of the function.

Vertical asymptotes are x = -4,

horizontal asymptotes are y = 0 and

slant asymptotes are y = x -4.

The ratio of losing to the total number of possible outcomes is 99.992:100, or 12499:12500.

In the game of Lucky Lauto, the probability of winning is 0.008%, which means that the probability of losing is 100% - 0.008% = 99.992%. This is the complement of the probability of winning, as the two probabilities must add up to 100%.

The ratio of the number of ways to succeed to the total number of ways that an experiment can happen is given by the probability of success. In this case, the probability of winning is 0.008%, so the ratio of winning to the total number of possible outcomes is 0.008:100, or 1:12500.

Similarly, the ratio of losing to the total number of possible outcomes is 99.992:100, or 12499:12500.

The scenario where one of the artists is not working is helpful in finding the domain and range of their work hours. This scenario shows the maximum number of hours one artist would need to work when the other artist is not working. For instance, if Philipe is not working, Claude would have to work for 15 hours (60 caricatures ÷ 4 caricatures per hour) to meet their goal. Similarly, if Claude is not working, Philipe would have to work for 20 hours (60 caricatures ÷ 3 caricatures per hour) to meet their goal.
