Answer:
(-2, -2)
Step-by-step explanation:
The midpoint M is calculated from end points A and B as ...
M = (A +B)/2
Solving for end point B, we get ...
2M = A +B . . . . . . multiply by 2
B = 2M -A . . . . . . subtract A
Then the other end point is ...
B = 2(4, 3) -(10, 8) = (2·4 -10, 2·3 -8) = (8-10, 6-8)
B = (-2, -2)
The other end point has coordinates (-2, -2).

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)

A robot is on the surface of Mars. The angle of depression from a camera in the robot to a rock on the surface of Mars is 14.12. The camera is 190.0 cm above the
surface. How far is the camera from the rock?
The camera is cm from the rock
Round to the nearest tenth as needed.)
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
Rock is 778.8 cm from the camera

which number line represents the solution set for the inequality
3(8-4x) < 6(x-5) ?
Answer:
Second number line(from top to bottom).
Step-by-step explanation:
We are given the following inequality:
[tex]3(8 - 4x) < 6(x - 5)[/tex]
It is solved similarly to an equality, so:
[tex]24 - 12x < 6x - 30[/tex]
[tex]-18x < -54[/tex]
Multiplying by -1, the signal changes from < to >. So
[tex]18x > 54[/tex]
[tex]x > \frac{54}{18}[/tex]
[tex]x > 3[/tex]
Thus the correct answer is given by the second number line.

O 15
O 18
Answer:
first option
Step-by-step explanation:
3x = 90 degree (being perpendicular)
x = 90/3
x = 30 degree
substitute the value of x
2x + 3y = 90 degree (being perpendicualr)
2*30 + 3y = 90
60 + 3y = 90
3y = 90 - 60
y = 30/3
y = 10 degree

A health care organization, StarCare, wants to implement a program to increase use of diabetes care services. In the past StarCare has billed insurance companies $350 per group session on cardiac care, a similar service, and thus plans to bill $350 for the diabetes group sessions. Operational expenses for the diabetes care services will be $1,000. Because StarCare is concerned with quality of services, it plans to have a consistent group size of 20 participants. However, the number of group facilitators will vary based on the number of diabetes care group participants. For every participant, it costs StarCare $300 in facilitator salary and other expenses. StarCare will only do one session if it is profitable. Based on this information, what are the (a) fixed costs for the proposed diabetes care program and the (b) the total variable costs for 20 participants?
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.

A sandwich costs $4.20 and a fruit drink costs $1.80. There is a 8% tax. How much
change will you get from a $10 dollar bill after purchasing both the sandwich and drink
(and paying tax of course)?
A. $6.48
B. $3.52
C. $3.70
D. $3.90
Answer:
B. 3.52
Step-by-step explanation:
4.20+1.80=6.00
6.00 x .08 (8% tax)=.48 tax
6.00+ .48=6.48 total cost
10.00-6.48=3.52 change from a $10 bill
Two dice are thrown together. Use a tree diagram to find the probability that both numbers are less than 5
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 %
What is Probability?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

Suppose a random sample of size 50 is selected from a population with μ = 10. Find the value of the standard error of the mean in each of the following cases (use the finite population correction factor if appropriate). Round your answers to two decimal places.
a. The population size is infinite.
b. The population size is N = 50,000.
c. The population size is N = 5000.
d. The population size is N = 500.
In the question, it's σ = 10 and not μ = 10.
Answer:
A) σ_x = 1.4142
B) σ_x = 1.4135
C) σ_x = 1.4073
D) σ_x = 1.343
Step-by-step explanation:
We are given;
n = 50
σ = 10
A) Formula for standard error of the mean for infinite size is;
σ_x = σ/√n
Thus;
σ_x = 10/√50
σ_x = 1.4142
B) When population is finite, we use correction factor and thus, we have;
σ_x = [√((N - n)/(N - 1)] × σ/√n
N = 50,000
Thus;
σ_x = [√((50000 - 50)/(50000 - 1)] × 10/√50
σ_x = 1.4135
C) N = 5000
Thus;
σ_x = [√((5000 - 50)/(5000 - 1)] × 10/√50
σ_x = 1.4073
D) N = 500
Thus;
σ_x = [√((500 - 50)/(500 - 1)] × 10/√50
σ_x = 1.343
The measure of an angle ABC is 50°,AD bisects angle BAC, and DC bisects angle BCA. The measure of angle ADC is what?
9514 1404 393
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

The circumference of a circle is 9.22cm
Find the length of the diameter.
Give your answer rounded to 2 DP.
de
cm
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:
Given :-Circumference of circle = 9.22 cmTo Find : -Length of diameter, dFormula Used :-Circumference of circle = π × dwhere , d is the length of diameterSolution:-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.
