Answer:

[tex]x = 4\\y = 9[/tex] hours

Step-by-step explanation:

Given -

x represents the number of hours lifeguarding and y represents the number of hours landscaping

[tex]x+ y = 13[/tex] -----Eq ( 1 )

and

[tex]20 * x + 10 * y = 170[/tex] -----Eq ( 2 )

Substituting the value of [tex]x = 13-y[/tex] in equation 2, we get -

[tex]20* (13 - y) + 10 y = 170[/tex]

[tex]260 - 20 y + 10 y = 170\\10y = 90\\y = 9[/tex]

[tex]x = 13-9 = 4[/tex]

Answer:

ang 4 = 60°

Step-by-step explanation:

ang 1 and ang 4 are Linear pair or supplementary angles.

ang 1 + ang 4 = 180

120° + ang 4 = 180° (Putting the value of ang 1)

ang 4 = 180° - 120°

ang 4 = 60°

Step-by-step explanation:

[tex]\text{The data given for the quality measurement and other criteria can be seen below:}[/tex]

Quality management      Excellent      Good      Fair      Total

Excellent                             40                   25         5             70

Good                                   35                    35        10            80

Fair                                       25                   10         15             50

Total                                    100                   70        30           200

The null and alternative hypothesis:

[tex]\mathbf{H_o: \text{the quality management and reputation are independent} }[/tex]

[tex]\mathbf{H_a: \text{the quality management and reputation are not independent} }[/tex]

The expected value is calculated by using the formula:

[tex]E=\dfrac{row \ total \times column \ total }{table \ total}[/tex]

After using the formula to calculate the table above; we have:

The expected values of the data to be:

Quality management     Excellent         Good      Fair      Total

Excellent                            35                  24.5       10.5      70

Good                                  40                   28         1.2         80

Fair                                     25                  17.5        7.5         50

Total                                   100                  70        30           200

Degree of freedom = ( row - 1 ) × ( column -1 )

[tex]= (3 - 1 ) \times (3 -1)[/tex]

[tex]= 2\times 2[/tex]

[tex]=4[/tex]

[tex]\text{The p-value at level of significance of 0.05 and degree of freedom of 4 = }\mathbf{0.0019}[/tex]

Decision rule: To reject the [tex]\mathbf{H_o}[/tex] if the p-value is less than the ∝

Conclusion: We reject the [tex]\mathbf{H_o}[/tex] and conclude that quality management and reputation are not independent.

(B)[tex]\text{The P-value here implies that in case that there is no dependence between the two ratings, }[/tex][tex]\text{the probability that they will seem to show at least this kind of strong dependence is 0.0019.}[/tex]

[tex]\text{Thus, the probability that they will seem to show at least this kind of strong independence is =}[/tex][tex]\mathbf{0.0019}[/tex]

Answer:

[tex]y = -x^2+3x+4[/tex]

Step-by-step explanation:

( -1, 0) , (0, 4) , (4, 0)

y = a(x − b)(x − c)

x-intercept = -1

x = -1

(x + 1) = 0

x-intercept = 4

x = 4

(x - 4) = 0

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

4 = a(0 + 1)(0 - 4)

4 = a (1)(-4)

4 = -4a

a = -1

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

[tex]y = -x^2+3x+4[/tex]

Answer:   M = -20w + 450

Step-by-step explanation:

M = -20w + 450

450 is the amount in his bank account; because he is spending $20 per weeks, so it's -20w.

Answer:

From top to bottom:

[tex]0, 1, 2, -8, -8[/tex]

Step-by-step explanation:

We are given the piecewise function:

[tex]g(x) = \left\{ \begin{array}{ll} 0.5x+1 & \text{if } x \leq 2 \\ -8 & \text{if } x > 2 \end{array} \right.[/tex]

Row 1:

We want to find g(-2).

Since -2 is less than (or equal to) 2, we will use the first equation. Thus:

[tex]g(-2)=0.5(-2)+1=-1+1=0[/tex]

Row 2:

Likewise, 0 is less than or equal to 2. We will continue to use the first equation:

[tex]g(0)=0.5(0)+1=1[/tex]

Row 3:

2 is not less than 2 but it is equal to 2. So we will continue to use the first equation:

[tex]g(2)=0.5(2)+1=1+1=2[/tex]

Row 4 and 5:

Both 4 and 6 are greater than 2. Thus, we will use the second equation. Therefore:

[tex]g(4)=-8\text{ and } g(6)=-8[/tex]

Answer:

The vertical axis on trending charts should almost always start at zero. The reason it's almost always is because you may have trending data that contains negative values or fractions. In those situations, it's generally best to keep Excel's default scaling.

There are no domain restrictions, even though there is a variable under the radical. Since , can never be negative. The least it can be is , so there is no danger of taking the square root of a negative number.

Answer:

- 18

Step-by-step explanation:

arithmetic  sequences are in form:

a(n)=a(o)+d(n-1)

sum are in form:

s(n)=[a(0)+a(n)](n/2)

three middle terms is:

10th, 11th, 12th term

How to think: 21 = 10+1+10 --> middle 3 is 10,11,12

sum of these 3 terms:

a(10)+a(11)+a(12)

=a(o)+9d+a(0)+10d+a(0)+11d

=3a(0)+30d=126

a(0)+10d=42 ......(equation 1)

Last three terms is:

19th, 20th, 21th

a(19)+a(20)+a(21)

=a(0)+18d+a(0)+19d+a(0)+20d

=3a(0)+57d=288

a(0)+19d=96 ......(equation 2)

now you have

a(0)+10d=42 ......(equation 1)

a(0)+19d=96 ......(equation 2)

solve and gives

d=6

a(0)= -18

Answer:

∠A is equal to 73°

Step-by-step explanation:

Because the two lines that move roughly bottom/left to top/right are marked as being parallel, we can say that ∠A + ∠B = 180°

With that we can take the two equations at the top, and add them together for a sum of 180°:

6x - 35° + 3x + 53° = 180°

9x + 18° = 180°

x + 2° = 20°

x = 18°

Now that we have x, we can solve for ∠A:

∠A = 6x - 35°

∠A = 6(18°) - 35°

∠A = 108° - 35°

∠A = 73°

We can test our answer by solving for ∠B.  We know that ∠A and ∠B add up to 180°, so ∠B = 180° - ∠A = (180 - 73)° = 107°.  Now let's solve for be given x and the original equation, and see if we have the right numbers:

∠B = 3x + 53°

∠B = 3(18°) + 53°

∠B = 54° + 53°

∠B = 107°

Which matches up, showing us that we have the correct answer.

Answer:

Total surface area = 340 cm²

Step-by-step explanation:

Surface area of the given prism = Area of two bases + Area of its lateral surfaces

Area of pentagonal base = [tex]\frac{1}{2}(\text{Apothem)}(\text{Perimeter})[/tex]

                                          = [tex]\frac{1}{2}(3.6)(5\times 5)[/tex]

                                          = 45 cm²

Area of the lateral sides of the prism = Perimeter of the pentagonal base × height

= (5×5)×10

= 250 cm²

Total surface area of the prism = 2(45) + 250

                                                     = 90 + 250

                                                     = 340 cm²

Answer:

45°

Step-by-step explanation:

Given,

x° = (90-x)° [Alternate exterior angles]

=> 90 - x = x

=> 90 = x + x

=> 90 = 2x

[tex] = > x = \frac{90}{2} [/tex]
