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 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.

Answers

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 height

As 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

Taylor can clean pools at a constant rate of 25 pools per hour. How many pools can Taylor clean in 25 hours?

Answers

Answer 625 pools.. Explanation: If she can clean 25 pools per hour, to see how many she can clean in 25 hours mutiply 25 times 25 and that give you 625

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

Answers

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.

Can somebody explain how to do this

Answers

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

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?

Answers

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.

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:

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

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.​

Answers

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.
