Answer:

The proportion of sampled students that complete their degree is 0.791.

Step-by-step explanation:

A proportion is the number of desired outcomes divided by the number of total outcomes.

a)Calculate the proportion of sampled students that complete their degree.

110 students sampled.

87 went on to complete their degree.

p = 87/110 = 0.791

The proportion of sampled students that complete their degree is 0.791.

This is the inequality

Answer:

y = 4x - 6

Step-by-step explanation:

Given the following data;

Slope, m = 4

Intercept, c = -6

To write the equation of line in the slope-intercept form;

The standard equation of straight line is given by the formula;

y = mx + c

Where;

m is the slope.

x and y are the points

c is the intercept.

Substituting the values, we have;

y = 4x + (-6)

y = 4x - 6

Answer:

J. 19.7

Step-by-step explanation:

SOH(sine = opposite side/hypotenuse) CAH TOA

sin 80° = RS/20

=> 0.985 = RS/20

=> RS = 20 × 0.985 = 19.7

Answer:

30 values ; greater than or equal to 10 and less Than or equal to 39

Step-by-step explanation:

Counting the number of leaves in the plot, we have 30 leaf values. This gives the number of dataset.

The minimum value is the number created by the combination of the least stem value and the lowest leaf value, which is 10

The maximum value is obtained from the combination of the highest stem and leaf value. The highest value is 39

Answer:

[tex] x = \dfrac{10}{3}~~or~~x = -2 [/tex]

Step-by-step explanation:

(x,−1) and (4x−2,5) is 10

[tex] \sqrt{(4x - 2 - x)^2 + (-1 - 5)^2} = 10 [/tex]

[tex] (3x - 2)^2 + (-6)^2 = 100 [/tex]

[tex] 9x^2 - 12x + 4 + 36 = 100 [/tex]

[tex] 9x^2 - 12x + 40 = 100 [/tex]

[tex] 9x^2 - 12x - 60 = 0 [/tex]

[tex] 3x^2 - 4x - 20 = 0 [/tex]

[tex] 3x^2 - 10x + 6x - 20 = 0 [/tex]

[tex] x(3x - 10) + 2(3x - 10) = 0 [/tex]

[tex] (3x - 10)(x + 2) = 0 [/tex]

[tex] x = \dfrac{10}{3}~~or~~x = -2 [/tex]

Answer:

The right answer is C (235.5 mm^2)

Answer:

H0 : μD = μN

H0 : μD > μN

Test statistic = 2.192

Pvalue = 0.017

there is strong evidence that healthy adult eat more cookies for a snack when they are distracted with a computer game during lunch than when they are not.

Step-by-step explanation:

Given the data:

n1 = 22 ; x1 = 52.1 ; s1 = 45.1

n2 = 22 ; x2 = 27.1 ; s2 = 26.4

H0 : μD = μN

H0 : μD > μN

The test statistic :

(x1 - x2) ÷ (Sp*√(1/n1 + 1/n2))

Sp = (n1 - 1)s1² + (n2 - 1)s2²] ÷ (n1 + n2 - 2)

Sp = √[((21 * 45.1^2) + (21 * 26.4^2)) ÷ 42]

Sp = 36.952469

Test statistic :

(52.1 - 27.1) ÷ Sp * √(1/21 + 1/21))

25 ÷ (36.952469 * 0.3086066)

25 ÷ 11.4037758196954

Test statistic = 2.192

Using the Pvalue from Test statistic calculator :df = 42, Tscore = 2.192

Pvalue = 0.017

α = 0.05

Pvalue < α

Hence, there is strong evidence that healthy adult eat more cookies for a snack when they are distracted with a computer game during lunch than when they are not.

3rd of column 2

Answer: 1/36

Step-by-step explanation:

Your going to multiply 1/6 x 1/6 and you will get 1/36, because there are 6 slots, and you spin on x once, there is a 1/6 chance you will spin on it again, so that keeps a the 6/6 for all of the letters. But we are looking for f, there is also a 1/6 percent chance that it might land on that, 1/6 x 1/6 = 1/36

Answer:

Step-by-step explanation:

36 - 4

Step-by-step explanation:

(6x - 2)(6x + 2)

= (6x)(6x) + (6x)(-2) + (2)(6x) + (-2)(2)

= 36 - 12x + 12x - 4

= 36 - 4

Answer:

12 different types of sandwich could be made.

Step-by-step explanation:

Since I am making a sandwich at the cafeteria where they have 2 kinds of bread, 2 kinds of cheese, and 3 kinds of meat, to determine how many different sandwiches could I make the following calculations must be performed:

Bread x cheese x meat = X

2 x 2 x 3 = X

4 x 3 = X

12 = X

Therefore, 12 different types of sandwich could be made.

Answer:

YES

Step-by-step explanation:

(3/8)·64 = 24 seats in the first class carriage are being used.

(7/13)·(78)·3 = 126 seats in the standard carriages are being used, for a total of ...

 24 + 126 = 150 . . . occupied seats

The number of available seats is ...

 64 +3·78 = 298

so half the seats on the train will be 298/2 = 149 seats.

 150 > 149, so more than half the seats on the train are being used.

Answer:

-10x

Step-by-step explanation:

multiply -5 with 2x

-5×2x= -10x

Answer:

Basically, you have to multiply the term at the top with the one on the left of the corresponding box. In this case you have to multiply -5 with 2x.

[tex]-5\cdot \:2x=-10x[/tex]

Answer:

[tex]{\huge\blue{\fbox{{࿐αɴѕωєя࿐}}}}[/tex]

[tex]6(3 + 4) = 6(3) + 6(4) \\ 6(7) = 6(3) + 6(4) \\ 6 \times 7 = 6 \times 3 + 6 \times 4 \\ 42 = 18 + 24 \\ 42 = 42[/tex]
