Answer:
X : ___ 0 ____ 1 _____ 2 ______ 3
P(X) : _ 6/15 __ 5/15__ 3/15 ____ 1/15
Step-by-step explanation:
From the data, to produce a probability distribution for the data :
X : number of times blood is drawn ;
P(x) : probability that blood is drawn at X times
Hence, the probability distribution table for the data Given goes thus :
X : ___ 0 ____ 1 _____ 2 ______ 3
P(X) : _ 6/15 __ 5/15__ 3/15 ____ 1/15
Probability that blood is drawn 0 times = 6/15
Probability that blood is drawn 1 time = 5/15
Probability that blood is drawn 2 times = 3/15
Probability that blood is drawn 3 times = 1/15
(6/15 + 5/15 + 3/15 + 1/15) = 1

A truck can be rented from Company A for $160 a day plus 0.60 per mile. Company B charges $80 a day plus 0.70 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
At __ miles, the rental costs are the same from other company.
Answer:
800 miles
Step-by-step explanation:
Let the amount of miles = m
Company A charges a flat rate of $160 a day, and $0.60 per mile:
total = 0.60m + 160
Company B charges a flat rate of $80 a day, and $0.70 per mil:
total = 0.70m + 80
Set both equations equal to each other:
0.60m + 160 = 0.70m + 80
Isolate the variable, m. Note the equal sign, what you do to one side, you do to the other. Subtract 0.70m and 160 from both sides:
0.60m (-0.70m) + 160 (-160) = 0.70m (-0.70m) + 80 (-160)
0.60m - 0.70m = 80 - 160
Simplify:
-0.10m = -80
Isolate the variable, m. Divide -0.10 to both sides:
(-0.10m)/(-0.10) = (-80)/(-0.10)
m = 80/0.10
m = 800
At 800 miles, the rental costs are the same.
Express the rate as a unit rate.

Put the following equation of a line into slope-intercept form, simplifying all fractions. 2x + 8y = 24
Answer:
y=-1/4x+3
Step-by-step explanation:
2x+8y=24

Walter lived 2 years longer than his brother Martin. Walter was 79 at the time of his death. Which equation could be used to find Martin's age, a, at the
time of his death?
O a + 2 = 79
O 79 + 2 = a
O 79 + a = 2
O a- 79 = 2
In the isosceles triangle ABC
AB=AC
angle B -- (3x 32)º
angle (872x)"
Work out the value
of x.
Answer:
x = 4.5
Step-by-step explanation:
Angle B = angle C because it is an isosceles triangle.
3x32 = 87-2x
96 = 87-2x
reduce:
9 = 2x
x = 4.5
Talia has a daily budget of $94 for a car rental. Write and solve an inequality to find the greatest distance Talia can drive each day while staying in her budget
Answer:
Step-by-step explanation:
Distance traveled by Talia = x
Cost for travelling 'x' miles = x * 0.20 = 0.2x
Daily budget = $94
Inequality,
30 + 0.2x ≤ 94
Solution:
0.2x ≤ 94 - 30
0.2x ≤ 64 {Divide both sides by 0.2
x ≤ 64/0.2
x ≤ 320
Answer:
x ≤ 320

An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the triangle is x. Another side is 9 more than three times the length of the bottom of the triangle. The last side is 9 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle. What is the expression for the perimeter of the triangle?
Answer:
The perimeter of the triangle can be expressed as 5x + 18.
Step-by-step explanation:
Perimeter of an object is the sum of the length of its sides.
For the required triangle, we have;
length of the base = x
length of the second side = 3x + 9
length of the third side = x + 9
Perimeter of the triangle = length of the base + length of the second side + length of the third side
= x + (3x + 9) + (x + 9)
= x + 3x + 9 + x + 9
= 5x + 18
The perimeter of the triangle can be expressed as 5x + 18.

Given:
LMN is an equilateral triangle.
LM = LN = MN = 12 cm
To find:
The height of the triangle h.
Solution:
In a right angle triangle,
[tex]\sin \theta=\dfrac{Opposite}{Hypotenuse}[/tex]
[tex]\sin (60^\circ)=\dfrac{h}{12}[/tex]
[tex]\dfrac{\sqrt{3}}{2}=\dfrac{h}{12}[/tex]
Multiply both sides by 12.
[tex]\dfrac{\sqrt{3}}{2}\times 12=\dfrac{h}{12}\times 12[/tex]
[tex]6\sqrt{3}=h[/tex]
Therefore, the height of the triangle is [tex]6\sqrt{3}[/tex] cm.
find the slope of the line that passes through (6, 3) and (10, 6)
Step-by-step explanation:
3/4
insert 1st point into y=mx+b
3=m(6)+b
insert 2nd point into y=mx+b
6=m(10)+b
-----------------------------------
use system of equations to solve for m and b
b=3-6m
b=6-10m
3-6m=6-10m
4m=3
m=3/4
insert back into the equation
3=(3/4)6+b
3=9/2+b
3-9/2=b
-3/2=b
insert back into y=mx+b
m=slope
b=y-intercept
y=(3/4)x-3/2
slope=3/4
Hope that helps :)

calculate the perimeter of a rectangle with length 4+5y-3x and width 2x - 8y
Answer: p = - 6y - 2x + 8
Step-by-step explanation:
p = 2l + 2w
p = 2(4+5y-3x) + 2(2x - 8y)
p = 8 + 10y - 6x + 4x- 16y
p = - 6y - 2x + 8
Answer:
P=-2x-6y+8 i believe
Step-by-step explanation:
P= 2(4+5y-3x) + 2(2x-8y)
P= 8+10y-6x +4x-16y
=8+10y+−6x+4x+−16y
=(−6x+4x)+(10y+−16y)+(8)
=−2x−6y+8

Answer:
2
Step-by-step explanation:
The slope is the rise over the run. 2 simple coordinates I can see is (6,2) and (7,4). I usually like to visualize it instead of actually solving it mathematically. So, we can start at (6,2). The point (6,2) goes up 2 and 1 to the right in order to get (7,4.) So since the slope is rise over run ( y/x) it would be 2/1 because we went 2 up the y axis and 1 to the right of the x axis. So 2/1 is 2. Therefore, 2 is the answer. I'm sorry if my explaining isn't the best... I hope this helps though!!
