A sample of 14001400 computer chips revealed that 311% of the chips do not fail in the first 10001000 hours of their use. The company's promotional literature claimed that more than 28(% do not fail in the first 10001000 hours of their use. Is there sufficient evidence at the 0.050.05 level to support the company's claim
Answer:
There is sufficient evidence at 0.05 significant level to support company's claim.
Step-by-step explanation:
We have these informations from the question
n = 1400
P^ = 31% = 0.31
Alpha level = 5% = 0.05
Then we come up with the hypothesis
H0: P = 0.28
H1: P>0.28
From here we calculate the test statistic
z = p^ - p/√pq/n
P = 0.28
q = 1-0.28
= 0.72
z = 0.31-0.28/√(0.31*0.72)/1400
= 0.03/√0.0001594
= 0.03/0.012
= 2.5
Then we have a p value = 0.00621
The p value is less than significance level
0.00621<0.05
So the null hypothesis is rejected.
We conclude that There is sufficient evidence at 0.05 significant level to support company's claim.
What is the inverse of y= 3/2x -2
Answer:
f^-1(x) = (2x + 4) / 3
Step-by-step explanation:
- switch 'y' with 'x'
x = 3/2y - 2
- solve for 'y'
x + 2 = 3/2y
- multiply each side by 2
y = (2x + 4) / 3

The new video game that Greg wants to purchase is sold for $40 at Techno Hut and for $45 at Gamer World. If Greg has a 10% off coupon for all purchases at Techno Hut and a 15% off coupon for video games at Gamer World, which statement is true? A. After coupons, the game is the same price at both stores. B. After coupons, the game is $5.50 cheaper at Techno Hut. C. After coupons, the game is $2.75 cheaper at Gamer World. D. After coupons, the game is $2.25 cheaper at
Hey there!
The answer to your question is D.) After coupons, the game is $2.25 cheaper at Techno Hut
First, we will solve for the price of Techno Hut's game. Let's find the amount of the discount:
0.10 x 40
4
Then, we take the discount off the price:
40 - 4 = 36
The price of the game at Techno Hut is $36
Next, we find the price of the game at Gamer World. Let's find the amount of the discount:
0.15 x 45
6.75
Then, we take the discount off the price:
45 - 6.75 = 38.25
The price of the game at Gamer World is 38.25
Therefore, Techno Hut is cheaper.

The sum of h and 5 is equal to 8 less than 6 times y.
Answer:
h+5=(6y)-8
Step-by-step explanation:
The sum is addition. So it wants you to add h and 5 on one side. Do 6 and y in parentheses on the other side and it wants you to subtract 8 from what you got from 6 times y.

9. Jacob ordered 4 pizzas to be delivered
.
Each pizza costs $12.75.
Jacob gave the driver an 58 tip when the pizzas were delivered
Which of the following expressions could be used to determine Jacob's total cost?
O A 4(12.75 + 8)
OB. 4 (12.75) +8
OC. 4 (8) + 12.75
OD. 4 (12.75 - 8)
Answer:
A
Step-by-step explanation:
i think because it would equal to a logical number and estimation for the total cost (total for that sum is 83)
Find an equation of the plane consisting of all points that are equidistant from (-1, 1, -5) and (4, -5, 0).
Answer: the required equation is 5x - 6y + 5z = 7
Step-by-step explanation:
Given that;
points : (-1, 1, -5) and (4, -5, 0).
mid point : ( [(-1+4)/2], [(1-5)/2], [(-5+0)/2]
⇒ midpoint : ( 3/2, -2, -5/2 )
x₀ y₀ z₀
Direction vector n = [4-(-1)], [ -5 - 1], [ 0 - (-5)]
⇒ Direction vector n = < 5, -6, 5 >
General equation plane : n(x-x₀, y-y₀, z-z₀) = 0
so we substitute
⇒ (5, -6, 5) (x-3/2, y-(-2), z-(-5/2) ) = 0
⇒ (5, -6, 5) (x - 3/2, y + 2, z + 5/2) ) = 0
⇒ 5(x - 3/2) - 6(y + 2 ) + 5(z + 5/2) = 0
⇒ 5x - 15/2 - 6y - 12 + 5z + 25/2 = 0
⇒ 5x - 6y + 5z = 15/2 + 12 - 25/2
⇒ 5x - 6y + 5z = 7
Therefore, the required equation is 5x - 6y + 5z = 7

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have,
Mean of two number is 12 and range is 6.
let the two number be a and b
So, Mean = (a + b)/ 2
12 = (a + b)/ 2
a+ b= 24.........(1)
Now, range = 6
a - b = 6........(2)
Solving equation 1 and 2 we get
2a = 24-6
2a = 18
a= 9
and, b= 24 - 9
b = 15

Sal purchases a new gaming system and games for $530. The tax is 7%. How much would he spend in taxes only ?
Answer: 37.1
Step-by-step explanation: 530 x .07
Answer:
$37.10
Step-by-step explanation:
You have to take the total price and multiply it by the decimal equivalent of the sales tax. In this case, 7% = 0.07, and so 530 x 0.07 = 37.10. If you wanted to get the total price (for future reference) then you would simply add the tax total to the original price.

what is the answer to 5+5(9b - 7)
Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
5+5(9b - 7)
FIRST CASE (JUST EVALUATION)
Given the expression
[tex]5+5\left(9b-7\right)[/tex]
[tex]\mathrm{Apply\:the\:distributive\:law}:\quad \:a\left(b-c\right)=ab-ac[/tex]
[tex]5+5\left(9b-7\right)=5+5\cdot \:9b-5\cdot \:7[/tex]
[tex]=5+45b-35[/tex]
[tex]= 45b - 30[/tex]
Therefore, we conclude that:
[tex]5+5\left(9b-7\right)=45b-30[/tex]
SECOND CASE (Finding the value of b)
Assuming we have to determine the value of b
[tex]5+5(9b - 7) = 0[/tex]
As we have determined
[tex]5+5\left(9b-7\right)=45b-30[/tex]
so substituting [tex]5+5\left(9b-7\right)=45b-30[/tex] in the equation
[tex]45b-30 = 0[/tex]
Add 30 to both sides
[tex]45b-30+30=0+30[/tex]
Simplify
[tex]45b=30[/tex]
Divide both sides by 45
[tex]\frac{45b}{45}=\frac{30}{45}[/tex]
Simplify
[tex]b=\frac{2}{3}[/tex]
Therefore, the value of b = 2/3
