A. Find the sum.

Pls help me​

Answer:

85

Step-by-step explanation:

The sum of the angles inside a triangle is 180 degrees.

A circle is 360 degrees, making half of it be 180 as well.

Since there are 121 degrees already marked, subtract it from 180 and you will get 59 degrees.

36 + 59 = 95

180 - 95 = 85 degrees.

Answer:

x = 85

Step-by-step explanation:

angles of a triangle = 180 degrees (all angles must equal 180)

if you minus 121 from 180, it will give the interior angle which is 59 degrees

therefore 59 + 36 + x  = 180

to find x plus 59 and 36 = 95 degrees

180 - 95 = 85

x = 85 degrees

=========================================================

Work Shown:

mu = 27989 = population mean

sigma = 3250 = population standard deviation

z = (x-mu)/sigma

z*sigma = x-mu

x = z*sigma + mu

x = 0.34*3250 + 27989

x = 29,094

The salary of $29,094 corresponds to the z score of 0.34.

This indicates the salary $29,094 is exactly 0.34 standard deviation units above the mean.

Step-by-step explanation:

The amount of money in Devon's retirement account if she saves $587 each month for 40 years is $956,488.14.

The total amount of her money contributed is $956,488.14.

The formula that can be used to determine the future value of the retirement account is:

Future value = monthly contribution x annuity factor

Annuity factor = {[(1+r)^n] - 1} / r

Where:

{[(1.004375^480) - 1] / 0.004375} x  $587 = $956,488.14

Total contributions =  $587 x 12 x 40 = $281,760

Step-by-step explanation:

The direct material price variance of Saskatewan Can Company will be $6552.

From the information given, it should be noted that the direct material price variance will be calculated thus.

Firstly, the actual materials cost will be:

= Actual quantity × Actual price

= 218400 × $0.65

= $141960

The projected materials cost will be:

= 218400 × $0.62

= $135408

Therefore, the price variance will be:

= $141960 - $135408

= $6552

The altitude of the plane is 8 miles

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

we know that in the right triangle ABC

tan function is ratio of opposite side and adjacent side

tan(72°)=h/x

h=xtan(72°) ....... equation 1

In the right triangle ABD

tan(55°)=h/(x+3)

h=(x+3)tan(55°) ..... equation 2

From equation 1 and 2

xtan(72°)=(x+3)tan(55°)

xtan(72°)-xtan(55°)=3tan(55°)

x[tan(72°)-tan(55°)]=3tan(55°)

x=3tan(55°)/[tan(72°)-tan(55°)]

We have to find the value of h

h=xtan(72°)

h=[3tan(55°)*tan(72°)]/[tan(72°)-tan(55°)]

h=8 miles

Hence, the height is 8 miles of the plane.

I am guessing you meant y=-2(x-4)^3+1 from x^3

From the parent cubic function x^3,

a(x-k)^3+h is its transformation and it would be vertical stretch by a, followed by a horizontal translation by k and vertical translation by h

Your equation follows the same format it has a negative sign at the front before the ( ) which means a reflection over the x axis at the beginning

SO your graph is a

1.reflection over the x axis

Answer:

[tex]\displaystyle h(x) = x-\frac{13}{2}[/tex]

Step-by-step explanation:

We are given that:

[tex]\displaystyle g(x) = \int_{-1}^x f(t)\, dt[/tex]

And we want to write the equation for the tangent to the graph of g at x = 4.

First, determine g(4):

[tex]\displaystyle \begin{aligned} g(4) & = \int_{-1}^{(4)} f(t)\, dt \end{aligned}[/tex]

This is equivalent to the area of f from -1 to 4:

[tex]\displaystyle \begin{aligned} g(4) & = \frac{1}{2}(2)(3) + \frac{1}{2}(2)(-3)+\frac{1}{2}(-3+(-2))(1) \\ \\ & = \frac{1}{2}(6-6-5) \\ \\ & = -\frac{5}{2}\end{aligned}[/tex]

Note that areas under the x-axis are negative.

Find g'(4):

[tex]\displaystyle \begin{aligned} g'(x) = \frac{d}{dx}\left[ \int_{-1}^x f(t)\, dt\right]\end{aligned}[/tex]

By the Fundamental Theorem of Calculus:
[tex]\displaystyle \begin{aligned} g'(x) & = f'(x) \\ \\ g'(4) & = f'(4) \\ \\ & =1 \end{aligned}[/tex]

Note f is a line for 3 < x < 6 with a slope of 1.

Therefore:
[tex]\displaystyle \begin{aligned} h(x) -g(x_1) & = g'(x_1)(x-x_1) \\ \\ h(x) - \left(-\frac{5}{2}\right) & = (1)(x-(4)) \\ \\ h(x)& = (x-4) - \frac{5}{2} \\ \\ & = x - \frac{13}{2}\end{aligned}[/tex]

In conclusion, the equation of the tangent line is:
[tex]\displaystyle h(x) = x-\frac{13}{2}[/tex]

I'll help you

Step-by-step explanation:

In the given set of data, mean is 0.352, range is 0.86, median is 0.31, interquartile range is 0.28, mode is 0.12 and 0.24, and standard deviation is 0.81.

A data set is a certain number of data given in any order.

Given, the measurements for 13 children are: 0.10, 0.25, 0.50, 0.4, 0.12, 0.12, 0.24, 0.24, 0.31, 0.36, 0.42, 0.55, 0.96.

By rearranging the data set in ascending order we get:

(0.10, 0.12, 0.12, 0.24, 0.24, 0.25, 0.31, 0.36, 0.4, 0.42, 0.50, 0.55, 0.96.)

1. Therefore, mean

= (0.10 + 0.25 + 0.50 + 0.4 + 0.12 + 0.12 + 0.24 + 0.24 + 0.31 + 0.36 + 0.42 + 0.55 + 0.96)/13

= 4.57/13

= 0.352

2. Therefore, range

= (0.96 - 0.10)

= 0.86

3. Therefore, median = 0.31

4. Here, median of the first half of the data set is

= Q₁

= (0.12 + 0.24)/2

= 0.18

Again, median of the second half of the data set is

= Q₃

= (0.42 + 0.50)/2

= 0.46

Therefore, the interquartile range

= (Q₃ - Q₁)

= (0.46 - 0.18)

= 0.28

5. Therefore, mode = 0.12, 0.24

6. Therefore, standard deviation is

= √[(x₁ - X)² + (x₂ - X)² + (x₃ - X)² + (x₄ - X)² + (x₅ - X)² + (x₆ - X)² + (x₇ - X)² + (x₈ - X)² + (x₉ - X)² + (x₁₀ - X)² + (x₁₁ - X)² + (x₁₂ - X)² + (x₁₃ - X)²]

Here, x₁, x₂,......, x₁₃ are given data set in ascending order.

X = mean of the given data set.

Therefore, standard deviation is

= √[(0.10 - 0.352)² + (0.12 - 0.352)² + (0.12 - 0.352)² + (0.24 - 0.352)² + (0.24 - 0.352)² + (0.25 - 0.352)² + (0.31 - 0.352)² + (0.36 - 0.352)² + (0.40 - 0.352)² + (0.42 - 0.352)² + (0.50 - 0.352)² + (0.55 - 0.352)² + (0.96 - 0.352)²]

= √[.064 + 0.054 + 0.054 + 0.013 + 0.013 + 0.01 + 0.0018 + 0.00006 + 0.0023 + 0.0046 + 0.023 + 0.039 + 0.37]

= √(.6488)
