Find the area under the standard normal curve that lies outside the interval between following two values. Round the answers to at least four decimal places. (a)Find the area under the standard normal curve that lies outside the interval between -1.43 and 1.34.
Answer:
A = 0,16644
Step-by-step explanation:
The area (A₁) under the bell shape curve, from the left tail up to the point ( z score) 1,34 is:
For z (score ) = 1,34 A₁ = 0,9099
The area A₂ from the left tail up to z = -1,43 is
A₂ = 0,07634
Area A₂ is inside area A₁, the area A₃ inside the points - 1,43 and 1,34 is
A₃ = A₁ - A₂
A₃ = 0,9099 - 0,07634
A₃ = 0,83356
Finally area outside the interval - 1, 43 and 1,34 is A ( the area we were looking for) is
A = 1 - A₃
A = 1 - 0,83356
A = 0,16644

y’all please help asap
Answer:
b=−ax+4a+3x
a= b−3x −x+4
Step-by-step explanation:
The values of a and b make the solution of the equation x = -5 are 1 and -6
How to determine the values of a and b?The equation is given as:
a(4-x) = -3x+b
When x = -5, we have:
a(4+5) = -3(-5)+b
Evaluate the products
9a = 15 + b
Set a = 1
9(1) = 15 + b
Make b the subject
b = 9 - 15
b = -6
Hence, the values of a and b make the solution of the equation x = -5 are 1 and -6

No. The occurrence of the event "" does not affect the probability of the event "." D. Yes. The occurrence of the event "" does not affect the probability of the event "."
Answer:
The probability of selecting a male is 0.3151.
The events "male" and "driver" are not independent.
The correct option is B.
Step-by-step explanation:
The missing data is as follows:
Female Male Total
Driver 32759 11715 44474
Passenger 6534 6361 12895
Total 39293 18076 57369
The complete question is:
Determine P(male) and P(male|driver). Are the events "male" and "driver" independent?
Solution:
Compute the probability of selecting a male as follow:
[tex]P(M)=\frac{n(M)}{N}=\frac{18076 }{57369}=0.3151[/tex]
Thus, the probability of selecting a male is 0.3151.
Compute the probability of selecting a male given that he is a driver as follows:
[tex]P(M|D)=\frac{P(M\cap D)}{P(D)}=\frac{n(M\cap D)}{n(D)}=\frac{11715 }{44474}=0.2634[/tex]
Two events, say A and B, are independent if:
P (A|B) = P(A)
Here, P (M|D) ≠ P (M)
Thus, the events "male" and "driver" are not independent.
P(female)= .317
Determine P(femaleIpassenger)= .264
No. The occurrence of the event
"passenger" affects the probability of the event "female."
Paul’s dog weighs 12 pounds more that Issac’s dog. Together they weigh 50 pounds. How much does Issac dog weigh ???
Answer:
Issac's dog weighs 19 pounds
Step-by-step explanation:
Let x be Issac's dog's weight
Translate the problem into an algebraic expression: x + (x + 12) = 50Simplify: 2x + 12 = 50Subtract 12 from each side, so it now looks like this: 2x = 38Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 19I hope this helps!
Simplify the fraction
198/264
as much as possible
Answer:
What is 198/264 Simplified?
3/4 is the simplified fraction for 198/264.
Step-by-step explanation:
Answer:
3/4.
Step-by-step explanation:
Find the prime factors:
198 = 2 * 99
99 = 3 * 3 * 11
So 198 = 2 * 3 * 3 * 11.
264 = 4 * 66 = 2 *2 * 66
66 = 2 * 3 * 11
So 264 = 2 * 2 * 2 * 3 * 11.
Now we find the Greatest common factor os the 2 numbers:
It is 2 * 3 * 11 = 66.
Therefore we can now simplify the fraction:
198/66 / 264/66
= 3/4.

One half of a is 14 more than 2 times the number.find the number?
Answer:
Let n represent the number
One half of a number= ½ n
Now, the equation will be=
½ n =14+2n
On multiplying both sides by 2, we obtain
n=2(14+2n)
n=28+4n
On subtracting 4n from both the sides,we obtain
n-4n=28
-3n=28
On dividing both sides by -3, we obtain
n= -28/3

In the figure, m∠1=(2x+40)° and m∠8=(12x−20)° . PLEASE IM BEGGING FOR HELP
For what value of x is m∥n ?
Enter your answer in the box.
x =
Answer: x = 6
Step-by-step explanation:
Angles 1 and 8 are alternate exterior angles, so they are equal.
So you can create an equation to solve for x
12x−20 = 2x+40 Subtract 2x from both sides. Add 20 to both sides
10x = 60
x = 6
If you need the m∠1, Substitute 6 for x. (2x+40)° 2(6) +40= 12+40 m∠1= 52°
m∠8=(12x−20)° 12(6) - 20 = 72-20 m∠8 = 52°

x=6

The mean of four numbers is 2.6
One of the four numbers is 5
Find the mean of the other three numbers.
Answer:
Step-by-step explanation:
the "mean" just means the "average"
So if the average of four numbers = 2.6
To find the total of the four numbers, you would multiply 2.6 by 4.
2.6 x 4 = 10.4
One of the four numbers is 5. (given in the question)
This means that the total of the remaining three numbers is:
10.4 - 5 = 5.4
Then divide 5.4 by 3 to find the average of the 3 numbers.
Mean of the other 3 numbers = [tex]\frac{5.4}{3}[/tex] = ?

Answer:
c = -11
expression value = 245
c = 0
expression value = 3
c = 15
expression value = 453
Step-by-step explanation:
Given expression = [tex]2c^2 + 3[/tex]
for c = -11 , we put c in place of c in given expression
[tex]2(-11)^2 + 3 = 2(121) + 3 = 242 + 3 = 245[/tex]
for c= 0
[tex]2(0)^2 + 3 = 2(0) + 3 = 0 + 3 = 3[/tex]
for c = 15
