a normal distribution has a mean of 10 and a standard deviation of 1 what is the probability of selecting a number between 7 and 13?
Answer: 0.9974
Step-by-step explanation:
Let X be the random variable that follows the normal distribution \.
If mean ([tex]\mu[/tex]) = 10 and standard deviation ([tex]\sigma[/tex]) =1
then, the probability of selecting a number between 7 and 13 = [tex]P(7<X<13)[/tex]
[tex]=P(\dfrac{7-10}{1}<\dfrac{X-\mu}{\sigma}<\dfrac{13-10}{1})[/tex]
[tex]=P(-3<z<3)[/tex] [Since [tex]z=\dfrac{X-\mu}{\sigma}[/tex]]
[tex]=P(z<3)-P(z<-3) \ \ \ [P(z_1<Z<z_2)=P(Z<z_2)-P(Z<z_1)]\\\\= P(z<3)-(1-P(z<3))\ \ \ [P(Z<-z)=1-P(Z<z)]\\\\=2P(z<3)-1\\\\=2(0.9987)-1\ \ [\text{By p-value table}]\\\\= 0.9974[/tex]
Hence, the probability of selecting a number between 7 and 13 is 0.9974.

Answer:
x=5 over 2 (it's a fraction)
Step-by-step explanation:
STEP 1 distribute : 4-1 (2x+4)=5
4-2x-4=5
STEP 2 subtract: 4-2x-4=5
-2x=5
STEP 3 divide both sides of the equation by the same term:
-2x=5
-2x 5

STEP 4 simplify:
cancel the terms that are both the numerator and denominator
divide the numbers
x= - 5 over 2 (fraction)

Step 1: Simplify both sides of the inequality.
−4x−7≤20x+35
Step 2: Subtract 20x from both sides.
−4x−7−20x≤20x+35−20x

two water tanks release at the same time water tank a holds 6000 gallons of water and water is released from the fish tank at a rate of 2 gallons per minute water tank behold 8250 gallons of water and water is released at the rate of 3 gallons per minute after how many minutes will the Two Gallants hold the same amount of water
After t minutes, Tank A contains
6000 gal - (2 gal/min) t
while Tank B contains
8250 gal - (3 gal/min) t
The two tanks hold the same amount of water when these quantities are equal. Solve for t :
6000 gal - (2 gal/min) t = 8250 gal - (3 gal/min) t
(1 gal/min) t = 2250 gal
t = (2250 gal) / (1 gal/min) = 2250 min

Solve for x: |2x + 12| = 18
x = 3, x = −3
x = 3, x = −15
x = 15, x = −15
x = −3, x = 15
Answer:
x = 3 x = -15
Step-by-step explanation:
|2x + 12| = 18
There are two solutions to an absolute value equation, one positive and one negative
2x+12 = 18 2x+12 = -18
Subtract 12 from each side
2x+12-12 = 18-12 2x+12-12 = -18-12
2x = 6 2x = -30
Divide by 2
2x/2 = 6/2 2x/2 = -30/2
x = 3 x = -15

Triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C'.
Triangle A,B,C with vertices at A(negative 3, 6), B(2, 9), and C(1, 1)
Note: Consider we need to find the vertices of the triangle A'B'C'
Given:
Triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C'.
Triangle A,B,C with vertices at A(-3, 6), B(2, 9), and C(1, 1).
To find:
The vertices of the triangle A'B'C'.
Solution:
If triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C', then
[tex](x,y)\to (y,-x)[/tex]
Using this rule, we get
[tex]A(-3,6)\to A'(6,3)[/tex]
[tex]B(2,9)\to B'(9,-2)[/tex]
[tex]C(1,1)\to C'(1,-1)[/tex]
Therefore, the vertices of A'B'C' are A'(6,3), B'(9,-2) and C'(1,-1).

4 students is blank% of 20 students?
Answer:
4 students is 20% of 20 students.
Step-by-step explanation:
We can say that 20 students represent 100% and that 4 students represent x% of all students. Then we can use the proportion: 20 : 4 = 100 : x, or 20 / 4 = 100 / x. Then we will cross multiply: 20 x = 4 * 100, 20 x = 400, x = 400 : 20 , x = 20 %. Also we can say that 4 = 1/5 * 20 and 1/5 * 100 = 20 %
4 students are 20 percent of 20 students.
What is the percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
We can say that 20 students represent 100% and that 4 students represent x% of all students.
Thus, we can use the proportion:
20 : 4 = 100: x, or 20 / 4 = 100 / x.
cross multiply
20 x = 4 * 100
20 x = 400
x = 400: 20
x = 20 %.
therefore, we can say that 4 students are 20 percent of 20 students.
