b) w = 4
c) w = 48
d) w = 8

Answer:

778.1 cm

Step-by-step explanation:

The solution triangle attached below :

Using trigonometry :

θ = 90 - 14.12 = 75.88°

Cos θ = Adjacent / hypotenus

Cos 75.88 = 190 / d

d = 190 / cos 75.88

d = 778.83

Answer:

20/7 or 13

Step-by-step explanation:

Answer:

20/7 doesn't reduce, so it's 20/7

if you mean 20- 7 it's 13

the proper fraction would be 2 remainder 6, 2.6, 2 and 6/10, or 2 and 3/5 simplified.

Solution :

Given :

Equation :

y = 6.3333 x + 53.0298

Here, x = number of hours studied

         y = the exam score

a). To predict the exam score, we have to replace x in the least square regression line by 2 :

   y = 6.3333 x + 53.0298

   y = 6.3333 (2) + 53.0298

      = 65.6964

Thus he predicted exam score is 65.6964

b). The slope is the co-efficient of x in the least squares regression line :

  Slope = 6.3333

 The slope represents the average increase in y as x increases by 1.

  The exam score increases on average by 6.3333 points per hour studied.

c). The mean score of the [tex]\text{ students who did not study}[/tex] (studied 0 hours) is obtained by replacing x in the least squares regression line by 0 :

  y = 6.3333 x + 53.0298        

 y = 6.3333 (0) + 53.0298

    = 53.0298

d). To predict the exam score of a student who studied 5 hours, we replace x in the least squares regression line by 2 :

   y = 6.3333 x + 53.0298

   y = 6.3333 (5) + 53.0298

   y = 84.6963

Thus the average exam score of a student who studied 5 hours is 84.6963

Since the actual exam score 81 is less than the average exam score of 84.6963 the student's exam score is below the average.

Answer:

a) The fixed cost is $1350.

b) Total variable cost is $6000.

Step-by-step explanation:

a) The fixed cost = Operational cost + Insurance company bill.

                           = $ 1000  + 350 = $1350.

b) Variable cost:-

The number of facilitators = 20.

The salary for each facilitator = $300.

Total variable cost = $300 x 20 = $6000.

Answer:

C. 1/3

Hope this helps!:)

Answer:

1/3

Step-by-step explanation:

The equation is in slope intercept form

y = mx+b where m is the slope and b is the y intercept

f(x) = -2/9x + 1/3

The slope is -2/9  and the y intercept is 1/3

Answer:

.12

Step-by-step explanation:

set up two ratios the same way  [tex]\frac{x}{y}[/tex]

[tex]\frac{4.8}{.09}[/tex] = [tex]\frac{6.4}{y}[/tex]

cross multiply and solve for y

4.8(y) = .09(6.4)

4.8y = .576

y = .12

Answer:

  115°

Step-by-step explanation:

Let A, B, C represent the vertex angle measures of ΔABC. Then the sum of angles in ΔADC is ...

  A/2 +∠ADC + C/2 = 180°

Multiplying by 2 gives ...

  A + C + 2×∠ADC = 360°

From the given information, we know ...

  A + C + 50° = 180° . . . . . sum of angles in ΔABC

This lets us write an expression for (A +C):

  A + C = 130° . . . . . . . . subtract 50° from the previous equation

Substituting for A+C, we get ...

  130° + 2×∠ADC = 360°

  2×∠ADC = 230° . . . . . . . . . subtract 130°

  ∠ADC = 115° . . . . . . . . . . . divide by 2

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

2 dice = 12 numbers

1, 2, 3, 4 and 1, 2, 3, 4 are less than five.

This is a total of 8 numbers.

[tex]\frac{8}{12} =\frac{8/4}{12/4}=\frac{2}{3}[/tex]

The probability that both numbers are less than 5 on throwing 2 dices is given by P ( A ) = 4/9 = 44.44 %

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

Let the probability that both numbers are less than 5 on throwing 2 dices be represented as P ( A )

Now , the total number of outcomes for throwing 2 dices = 36 outcomes

And , out of these 36 possible outcomes, there are 16 outcomes where both numbers are less than 5

{(1,1), (1,2), (1,3), (2,1), (2,2), (2,3),

(3,1), (3,2), (3,3), (4,1), (4,2), (4,3),

(1,4), (2,4), (3,4), (4,4)}

So , the number of possible outcomes = 16

And , probability P ( A ) = 16/36

P ( A ) = 4/9

Hence , the probability is 4/9

Answer:

Step-by-step explanation:

circumference of a circle = 2πr

9.22 cm = 2*3.14*r

9.22 cm = 6.28*r

9.22 cm /6.28 = r

1.4681 = r

diameter of a circle = 2*r

=2*1.4681

=2.9362

=2.9 cm

Answer:

The Length of diameter of circle is 2.93cm.

Step-by-step explanation:

Using formula

Circumference of circle = π × d

substitute the values

9.22 cm = π × d

Using value of π = 3.14

9.22 cm = 3.14 × d

divide each side by 3.14

9.22 cm / 3.14 = 3.14 × d /3.14

2.93 cm = d

Hence, The Length of diameter of circle is 2.93cm.

Answer:

Part A = B. 1 ÷ 1/3 = 3

Part B = 27 brownies

Step-by-step explanation:

Part A

From the ingredients given in above question:

1/3 cup of butter = 1 batch of brownies

Hence: 1 cup of butter = x

Cross Multiply

1/3 cup of butter × x = 1 cup of butter × 1 batch of brownies

x = 1 cup of butter × 1 batch of brownies/1/3 cup of butter

x = 1 batch of brownies ÷ 1/3

x = 1 batch of brownies × 3/1

x = 3 batches of brownies

Hence, the number brownies Jackson can make with 1 cup of butter Is 3 batches of brownies

Therefore, the equation you can use to solve the problem is Option B. 1 ÷ 1/3 = 3

Part B

If each brownie is 1/9 of a batch, how many brownies did he make?

We know from Part A that Jackson made 3 batches of brownies hence:

1/9 of a batch of brownies = 1 brownie

3 batches of brownies = x

Cross Multiply

1/9 of a batch of brownies × x = 1 brownie × 3 batches of brownies

x = 1 brownie × 3 batches of brownies/ 1/9 of a batch of brownies

x =( 3 ÷ 1/9) brownies

x = ( 3 × 9/1) brownies

x = 27 brownies

Therefore, the number of brownies he made was 27 brownies.
