Answer:
Option c) [tex]0.25[/tex]
Step-by-step explanation:
[tex]p(red \cap truck) = p(red) \times p(truck)[/tex] ([tex]truck[/tex] is referring to pickup truck)
[tex]0.06=p(red) \times 0.24[/tex] (given that the probability of a red pickup truck is 0.06 and the probability of a pickup truck is 0.24)
[tex]p(red)=0.06\div0.24[/tex]
[tex]p(red)=0.25[/tex]
∴ The probability that a vehicle is red is [tex]0.25[/tex].

The diagram shows a sector of a circle radius 11 cm.
Show that the perimeter of the sector
is greater than 47.5 cm.
135°
11 cm
Answer:
Perimeter of sector is 47.93 cm which is greater than 47.5 cm
Step-by-step explanation:
Mathematically, the perimeter of a sector is length of the arc plus 2 radii
The length of the arc is;
theta/360 * 2 * pi * r
where theta is the angle subtended by the arc at the center of the circle
Thus, we have
135/360 * 2 * 22/7 * 11 = 25.93
Add 2 radii = 25.93 + 2(11) = 47.93 cm
This is greater than what we are asked to calculate and thus we have shown what we are asked to show
Answer:
47.9cm>47.5cm
Step-by-step explanation:
135(angle) /360 x 2 pi r (to give arc of the sector)
135/360 x 2 x 3.142 x 11 = 25.92cm
add 11 + 11 (radius)
25.92 + 22= 47.9cm

Complete the real-world situation that could be modeled by the equation 150 − 8x = 170 − 12x. Xavier has $150 in his lunch account. He spends $ for lunch each day. Zack has $ in his lunch account. He spends $ each day. After how many days will the boys have the same amount of money in their accounts?
Answer:
5 days
Step-by-step explanation:
The question above is modeled by the equation :
150 − 8x = 170 − 12x.
After how many days will both have ye same amount :
Number of days = x
Collect like terms
-8x + 12x = 170 - 150
4x = 20
x = 20/4
x = 5 days
The boys will have the same amount in their account after 5 days.

Can somebody explain how to do this
Answer:
The answer is 46.
Step-by-step explanation:
First, you will have to add up both functions in order to find the new expression for (g + f)(a) :
g(a) + f(a) = (g + f)(a)
(g + f)(a) = 3a + 3 + 2a - 2
(g + f)(a) = 5a + 1
Next, you have to substitute a = 9 into the function :
(g + f)(9) = 5(9) + 1
(g + f)(9) = 46

have in 7 years?
Answer:
9940
Step-by-step explanation:
its easy please give brainlist
Answer:
~10525.41 after 7 years
Step-by-step explanation:
y=a(1+r)^x
That's the equation for exponential growth
a= the starting amount
r= the rate at which it is growing
x=years
with that information
a=7000
r=6% or 0.06
so y=7000(1+0.06)^x -> y=7000(1.06)^x
x=7
y=7000(1.06)^7
y~10525.41

Answer:
4 btw lovinggg the M !!!!!
Step-by-step explanation:
Answer:
Undefined
Step-by-step explanation:
To find slope, you need the difference of y over the difference of x.
For example, let's use (-8,8) and (-8,3).
Difference of y: 8-3
Difference of x: -8-(-8) (Note that the order of the x values must be the same as the order of the corresponding y values of the coordinate)
(8-3)/(-8+8)
= 5/0
Now, we see that we have to divide by 0, except it's impossible to divide by 0, so the slope is left as undefined.
Does anyone have the answer key to these proofs? They are Mrs. E Teaches Math introductory proofs. There are 14 total. I've done 1-9.
Statement 1: 2AB = AC
Reason 1: Given
--------------------------------------------
Statement 2: AC = AB+BC
Reason 2: Segment addition postulate (which your teacher abbreviated to "Seg + Post")
--------------------------------------------
Statement 3: 2AB = AB+BC
Reason 3: Substitution
--------------------------------------------
Statement 4: 2AB-AB = AB+BC-AB
Reason 4: Subtraction Property of Equality
---------------------------------------------
Statement 5: AB = BC
Reason 5: Combine like terms
----------------------------------------------
Notes:
The first reason is "given" since we just simply restate what the instructions provide. If you are given multiple items, you list each one at a time. The segment addition postulate is where we break a line into smaller parts and then build it back together.Substitution is simply replacement. We've replaced AC with 2AB.The subtraction property of equality is the idea where we subtract the same thing from both sides. In statement 4, we're subtracting AB from both sides.The last statement of any proof is always the thing we're trying to prove. Once we reach such a statement, there's no need to go any further since the proof has concluded.the base of a triangle is 7 less than twice its height. If the area of the triangle is 102m^2, find the length of the base.
Answer:
The length of the base will be: 17 m
Step-by-step explanation:
Given the area of the triangle
[tex]A=102\:m^2[/tex]
Using the formula of Area of a triangle:
[tex]A=\frac{1}{2}\left(b\times h\right)[/tex]
Here,
'b' is the base'h' is the heightAs the base of a triangle is 7 less than twice its height.
so
[tex]b=2h-7[/tex]
so the formula of Area of a triangle becomes
[tex]102=\frac{1}{2}\left(\left(2h-7\right)\times \:h\right)[/tex]
[tex]204=h\left(2h-7\right)[/tex]
[tex]2h^2-7h=204[/tex]
[tex]2h^2-7h-204=0[/tex]
[tex]\left(2h+17\right)\left(h-12\right)=0[/tex]
[tex]2h+17=0\quad \mathrm{or}\quad \:h-12=0[/tex]
[tex]h=-\frac{17}{2},\:h=12[/tex]
As height can not be negative, so:
[tex]h=12[/tex] m
Hence, the length of the base:
[tex]b=2h-7[/tex]
[tex]= 2(12)-7[/tex]
[tex]=24-7[/tex]
[tex]= 17[/tex] m
Therefore, the length of the base will be: 17 m

Answer:
x = 22/3, x=14
Step-by-step explanation:
Start by isolating whatever is in the absolute value sign; in this case divide either side by 4
4|1-3/4x + 7| =10,
----------------- ----
4 4
|1-3/4x + 7| = 10/4 = 5/2,
now if we apply the absolute value rule we know that 1-3/4x + 7 will be equal to -5/2, and 5/2
1-3/4x + 7 = 5/2 and 1-3/4x + 7 = -5/2
-3/4x + 8 = 5/2,
-3/4x=5/2-8,
-3/4x = 5/2-16/2,
-3/4x = -11/2,
x = -11/2*-4/3 = 44/6 = 22/3
-3/4x+8 = -5/2
-3/4x = -5/2-8
-3/4x = -5/2-16/2
-3/4x = -21/2
x = -21/2*-4/3 = 82/6 = 14

Answer:
B. Yes, 3.5
Step-by-step explanation:
Proportional Variables
Two variables x,y are proportional if one of them can be calculated as the other variable time a fixed constant:
y = k.x
Or, equivalently:
k = y/x
k is called the constant of proportionality.
The table gives three points: (13,45.5) (14,49) (15,52.5)
To find out if the values correspond to a proportional relationship, we find the value of k for each pair:
k = 45.5 / 13 = 3.5
k = 49 / 14 = 3.5
k = 52.5 / 15 = 3.5
Since the value of k is the same for all the points, we conclude the table shows a direct proportional relationship and the constant of proportionality is 3.5

Answer:
f(x) = 2x^2 + 12x +10
Step by step solution:
x = 1 x = 5 y = 10
f(x) = a(x+1)(x+5)
f(0) = a(1)(5) = 10
5a = 10
Divide by 5
a = 2
f(x)= 2(x+1)(x+5)
f(x) = 2(x^2 +6x +5)
f(x) = 2x^2 + 12x +10

Taylor can clean pools at a constant rate of 25 pools per hour. How many pools can Taylor clean in 25 hours?
Taylor can clean 625 pools in 25 hours
If Taylor can clean pools at a constant rate of 25 pools per hour, this is expressed as:
25 pools = 1hour
We are to calculate the number of pools that Taylor can clean in 25 hours, this is expressed as;
x = 25 hours
Divide both expressions
25/x = 1/25
x = 25 * 25
x = 625 pools
Hence Taylor can clean 625 pools in 25 hours
