Answer:
The value of x is -3 and 2.
Step-by-step explanation:
First, you have to elaborate the equation :
[tex] {x}^{2} + x - 6 = 0[/tex]
[tex] {x}^{2} - 2x + 3x - 6 = 0[/tex]
Next, you can factorize it by taking out the like-terms :
[tex]x(x - 2) + 3(x - 2) = 0[/tex]
[tex](x + 3)(x - 2) = 0[/tex]
Lastly you have to solve it :
[tex]x + 3 = 0[/tex]
[tex]x = - 3[/tex]
[tex]x - 2 = 0[/tex]
[tex]x = 2[/tex]
Answer:
[tex]x = 2[/tex] or (look down)
Step-by-step explanation:
[tex]x^{2}[/tex]+[tex]x[/tex]−[tex]60[/tex] [tex]=[/tex] [tex]0[/tex]

Find the volume of a cone with radius 12 yd and height 4 yd. Use 3.14 for π. Compare the volumes of the two cones. Use pencil and paper. Pick different values for the radius and height and calculate the volume of two cones like the ones described here. Compare the volumes of these cones.
Answer:
Volume is 602.88
Step-by-step explanation:
Here, we are asked to
calculate the volume of the cone.
Mathematically, to do this, we need to use the formula for finding the volume of cone= 1/3 * pi *r^2 * h
now we know that radius is 12 yards and height 4 yards. Plugging these values we have;
V = 1/3 * 3.14 * 12^2 * 4
V = 602.88 inches^3

Two rectangular prisms, M and N, are mathematically similar. The volumes of M and N are 17 3 and 136 3, respectively. The height of N is 18 . Find the corresponding height of M.
Answer:
9 cm
Step-by-step explanation:
Volume of M= 17cm^3. Volume of N=136cm^3
Volume of N/Volume of M = k^3
136/17=8
Cube root of 8 =2
Now we know that k=2.
Height of N/2 =height of M
18/2= 9
Therefore, the height of M=9

The data below represents the number of medals won by the top ten countries in the 2014
Winter Olympics. If the mean is 20.4 and the standard deviation is 7.9, circle all values that
fall within one standard deviation of the mean.
6, 11, 15, 17, 19, 24, 25, 26, 28, 33
Answer:
You should circle:
15, 17, 19, 24, 25, 26, 28
Step-by-step explanation:
The values x that falls within 1 standard deviation of the mean are those which.
[tex]|x - 20.4| \leq 7.9[/tex]
6
|6 - 20.4| = 14.4 > 7.9
6 is not within 1 standard deviation of the mean.
11
|11 - 20.4| = 9.4 > 7.9
11 is not within 1 standard deviation of the mean.
15
|15 - 20.4| = 5.4 < 7.9
15 is within 1 standard deviation of the mean.
17
|17 - 20.4| = 3.4 < 7.9
17 is within 1 standard deviation of the mean.
19
|19 - 20.4| = 1.4 < 7.9
19 is within 1 standard deviation of the mean.
24
|24 - 20.4| = 3.6 < 7.9
24 is within 1 standard deviation of the mean.
25
|25 - 20.4| = 4.6 < 7.9
25 is within 1 standard deviation of the mean.
26
|26 - 20.4| = 5.6 < 7.9
26 is within 1 standard deviation of the mean.
28
|28 - 20.4| = 7.6 < 7.9
28 is within 1 standard deviation of the mean.
33
|33 - 20.4| = 12.6 > 7.9
33 is not within 1 standard deviation of the mean.
A cookie jar contains 3 chocolate chip cookies, 4 oatmeal raisin cookies, and 5 sugar cookies.
Event A = drawing a chocolate chip cookie on the first draw
Event B = drawing an oatmeal raisin cookie on the second draw

Only answer if you're sure please :)
A. 1/15
B. 1/11
C. 1/4
D. 4/11
Answer:
Answer B
Step-by-step explanation:
A is 1/4 bc there are 3 out of 12
B is 4/11 bc there are for oatmeal raisin and all in all 11 cookies left
so A*B is 1/4 * 4/11 = 4/44 = 1/11

A busy customer service agent handled 20 emails in 1/4 of a day. At that rate, how many emails could he handle in 1 day?
Step-by-step explanation:
20 mails in 1/4 day (0.25 day)
-> 1 day = 20/0.25 = 80 emails
A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
1/4 day = 20 emails
1 day = 80 emails
The number of emails he could handle in a day is 80 emails.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
Example:
1/2, 1/3 is a fraction.
4/8 = 1/2 is a fraction
6/8 = 3/4 is a fraction.
We have,
The number of emails handled in 1/4 of a day = 20 emails.
This can be written as,
1/4 day = 20 emails
Multiply 4 on both sides.
4 x 1/4 day = 4 x 20 emails
1 day = 80 emails
Thus,
1/4 day = 20 emails
1 day = 80 emails
The number of emails he could handle in a day is 80 emails.

Mags is 2 years older than Vector. Which equation will
help you find Mags' age (m) if you know Vector's age (v)?
v = m + 2
m = V + 2
V-2=m
Answer:
m = v + 2
Step-by-step explanation:
Since Mags (m) is 2 years older than Vector (v)
You can use the equation V + 2 which is Vector's age + 2 years. Which would be equal to Mags' age.

M = 3
....................
Answer:
m = 3
Step-by-step explanation:
10m = 10-5(m-7)
10m = -(5m-5×7)+10
10m = -(5m-35)+10
10m = -5m + 35 + 10
10m = -5m +45
15m = 45
15m/15 = 45/15
m = 3^2*5/3*5
m = 3^2-1
m = 3

If 8x=4
What is 2+12x?
Answer:
8
Step-by-step explanation:
If 8x = 4, then you can solve for x by dividing both sides by 8. Therefore, x = 4/8 or 1/2.
Then to solve 2 + 12x you simply plug in 1/2 for x.
2 + 12x
2 + 12(1/2)
2 + 6

There are 1300 students in a school. 48% of them are female. How many are male?
Answer:
676
Step-by-step explanation:
First find what 48 percent of 1300 is
1300*0.48=624
Then subtract the number of females from the total number of students.
1300 student -624 females=676 males.
Hope that's clear :)
Answer:
[tex]676[/tex]
Step-by-step explanation:
48 % of students are female. so first we have to fine the percentage of male.
[tex]48\% = female \\ 100\% - 48\% = 52\% \\ 52\% = male[/tex]
Now lets fine how many male students are there.

There are 20 students in a 5th grade class. Four of these students will be selected to be patrols. In how many ways can the four patrols be selected?
Answer:
4845 ways
Step-by-step explanation:
We need to form groups of four students among the total of 20 students, and the order of the students inside the group does not matter, so we have a combination problem.
To solve this problem, we just need to find the combination of 20 choose 4:
C(20, 4) = 20! / (16! * 4!) = 20 * 19 * 18 * 17 / (4 * 3 * 2) = 4845
There are 4845 ways of selecting this group of four patrols.

If the factors of quadratic function g are (x − 7) and (x + 3), what are the zeros of function g?
A.
-7 and -3
B.
-3 and 7
C.
3 and 7
D.
-7 and 3
Answer:
The correct option is (b).
Step-by-step explanation:
We are given with the factors of quadratic function. They are as follows :
(x − 7) and (x + 3)
It is required to find the zeroes of function g.
To find zeroes of function, it is required to put the factors equal to 0 i.e.
[tex](x-7)=0\\\\x=7[/tex]
and
[tex](x+3)=0\\\\x=-3[/tex]
From above calculations, we can say that the zeroes of function g are 7 and (-3). Hence, the correct option is (b).

Each homeroom must send two student representatives to each student council meeting. Mrs. Lincoln has 15 girls and 10 boys in her homeroom. If she randomly selects two students to attend the next meeting, find the probability of her choosing one girl and one boy?
Answer:
1/4
Step-by-step explanation:
Mrs. Lincoln has 15 girls and 10 boys in her homeroom. She randomly selects two students. The total number of students is 25.
The probability of choosing one girl is:
15 / 25 = 3 / 5
Now, 24 students are left.
The probability of choosing one boy is:
10 / 24 = 5 / 12
Therefore, the probability of choosing one girl and one boy is:
3 / 5 * 5 / 12
= 3 / 12
= 1/4
60% of what number is 150?
Answer:
90
Step-by-step explanation:
To solve this you must make a proportion of x/150 60/100. Then you need to find the relation between 100 and 150 which is x 1.5. Then apply the same thing to 60 which results in 90.
Answer: 250
You must set this up as a proportion
Remember the percent is always over 100
150/x=60/100
Then solve the proportion
60x=15000
Get the x by its self
15000/60 is 250
x=250
