Answer:

0.49

Step-by-step explanation:

We apply conditional probability to solve this question.

We have Events X and Events Y

P(X) = Probability Christine fails the course = ??? Unknown

P(Y) = Probability Christine finds a tutor

= 0.35

P(Y') = Probability Christine does not find a tutor = 1 - 0.35 = 0.75

P(X|Y) = Decrease in her probability of failing = 0.35

P(X|Y') = Probability that she will fail the course if she does not have a tutor

P(X) = P(X|Y) × P(Y) + P(X|Y') × P(Y')

P(X) = 0.35 × 0.75 + 0.65 × 0.35

P(X) = 0.2625 + 0.2275

P(X) = 0.49

The probability that Christine fails the course is 0.49

Answer:

15

Step-by-step explanation:

since both equations are set with a right angle, the equation must be equal to 90 degrees. So you set the equation as

13+x+4x+2=90

add the x variables together and the constants separately

15+5x=90

then subtract 15 from both sides.

15+5x=90

-15      -15

5x=75

then divide 5 from both sides.

75/5= 15

so x is 15 :).

Answer:

It shows a 90° angle split into 2 separate angles so,

[tex]13 + x + 4x + 2 = 90\\\\5x + 15 = 90\\\\5x = 75\\\\x = 15[/tex]

Basically, the total angle measure of the given angles [90°, (13 + x)°, and (4x + 2°) equals 180°. Take away 90 from 180 and you get 90, then solve for x using what's left: 13 + x + 4x + 2 = 90. You get x = 15.

Answer:

A

Step-by-step explanation:

(-8,8) is the solution of the equation y=-5/4x-2.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

The given equation is,

y=-5/4x-2,

To find solution for the given equation, solve with the help of options,

(A) (-8,8)

8=-5/4(-8)-2

8 = 10-2

8 = 8

(-8,8) is the solution of the equation

(B) (8,-8)

-8=-5/4(8)-2

-8 = -10-2

-8 = -12

(8,-8) can not be the solution of the equation.

(C) (-8,-12)

-12 = -5/4(-8)-2

-12 = 8

(-8,-12) can not be the solution of the equation.

(D) (1, −15/4)

-15/4 = -5/4(1)-2

-15/4 = -13/4

(1,--15/4) can not be the solution of the equation.

(-8,8) is the solution of the equation.

Answer:

10

Step-by-step explanation:

Since 12 is closer to 10 than 20, the nearest ten is 10, which is the answer.

Answer:

10

Step-by-step explanation:

This is the answer because:

1) We always have to look at the rounding digit (this digit is located right next to the tens digit in this problem).

2) Since the ones digit is smaller than 5, it has to round down to 10. If the digit was 5 or greater, than it would be 20.

Therefore, the answer is 10.

Answer:

21.2d + 12.4f

Step-by-step explanation:

Given that:

Width of rectangle = (5.5d+9.7f) centimeters

Length of rectangle = (5.1d-3.5f) centimeters

Perimeter of a rectangle : 2 (length + Width)

2 [(5.1d-3.5f) + (5.5d+9.7f)]

2[5.1d - 3.5f + 5.5d + 9.7f]

2[10.6d + 6.2f]

= 21.2d + 12.4f

Hence, the perimeter is :

21.2d + 12.4f)

Answer:

a) mean μ = 50     median M = 50   mode Md = 50

b) mean μ₂ = 52,5 median M = 52,5   mode Md = 52,5 all vales increased in 2,5 ( thousands of $) the same quantity of individuals incements

c) mean  μ₃ = 52,50 median M = 52,5 mode Md = 52,5 The same values obtain in b)

d) mean  μ₃ = 52,50 median M = 50 and Mode 50

Step-by-step explanation:

a) Mean μ is the average then:

30 30 45 50 50 50 55 55 60 75

μ = 50

The median M, is the central (fifth value) 50

And the mode

Md = 50

b) Adding 2,5 ( in thousands of $) to each one of the employees

32,5 32,5 47,5 52,5 52,5 52,5 57,5 57,5 62,5 77,5

The mean    μ₂ = 52,5 $, since the average value has to be increased by the common increased number

The median M = 52,5   and also the mode Md = 52,5

c)  31,5 31,5 47,25 52,5 52,5 52,5 57,75 57,75 63 78,75

The mean  μ₃ = 52,50

The median M = 52,50

The Mode Md = 52,50

d) 30 30 45 50 50 50 55 55 60 100

μ₄ = 52,5

Median M = 50

Mode Md = 50

Answer:

11. B 12. C 13. B

Step-by-step explanation:

11. Since segment MR bisects segment QO, side QP and side PO are equal. In the problem it states that angle MQP is congruent to angle ROP. The the angles QPM and OPR are vertical, so they are equal. That is enough evidence to conclude the answer.

12. ADC is bisected by BD, so that bisects AC too, which makes both sides equal. BD is perpendicular to AC, making right angles on both sides. The curves at angle A and angle C show that they are congruent. That should be enough evidence to show that it is congruent by ASA.

13. Triangle cannot be congruent by having the same angles, only similar since the lengths can be different. Congruent triangle means that the sides and angles are the same.

Answer:

y = -3/2x - 17

Step-by-step explanation:

First you need to find the slope, since the lines are parallel the slopes would be the same as points of the other line on the table. When finding the slope you get -3/2, when you have the slope you need to find the y-intercept or in other words in y=mx+b, the "b" in the equation. In order to find the y-intercept you have to plug in the values of the point (-10,-2) so then the equation would look like -2 = -3/2(-10) + b. Then you would solve for b. Then when you put the components together you get y = -3/2x - 17.

Answer:

125.6 cm²

Step-by-step explanation:

Area of the shaded region = area of larger circle - area of the smaller circle

Area of the smaller circle = πr²

π = 3.14, r = 3 cm

Area of smaller circle = 3.14*3² = 3.14*9 = 28.26 cm²

Area of larger circle = πr²

π = 3.14, r = 7

Area of larger circle = 3.14*7² = 3.14*49 = 153.86 cm²

Area of the shaded region = 153.86 - 28.26 = 125.6 cm²

Answer:

width = 3/10 mi

Step-by-step explanation:

area = length * width

width = area/length

width = (3/4 mi^2)/(2 1/2 mi)

width = (3/4 mi^2)/(5/2 mi)

width = 3/4 * 2/5 mi

width = 6/20 mi

width = 3/10 mi

Since ΔABC ≅ ΔXYZ,

By the property that says that "corresponding parts of the congruent triangles are congruent"

Corresponding angles (Including right angle) will be equal.

m∠A = m∠X = 180° - (90° + 37°) = 53°

m∠B = m∠Y = 90°

m∠C = m∠Z = 37°

Corresponding sides of the triangles will be equal.
