An experiment reported in Popular Science compared fuel economies for two types of similarly equipped diesel mini-trucks. Let us suppose that 12 Volkswagen and 10 Toyota trucks were tested in 90- kilometer-per-hour steady-paced trials. If the 12 Volkswagen trucks averaged 16 kilometers per liter with a standard deviation of 1.0 kilometer per liter and the 10 Toyota trucks averaged 11 kilometers per liter with a standard deviation of 0.8 kilometer per liter, construct a 90% confidence interval for the difference between the average kilometers per liter for these two mini-trucks. Assume that the distances per liter for the truck models are approximately normally distributed with equal variances.
Answer:
CI= [4.324 , 5.6758]
Step-by-step explanation:
The 90 % confidence interval for the normal distribution is given by
(x`1- x2` ) ± t ∝/2 (υ) .Sp √1/n1 + 1/n2
where Sp = √[n1-1 (s1)² + n2-1 (s2)²]/n1+n2-2
and n1= 12 n2=10
x1`= 16 km x`2 = 11km
s1= 1km s2= 0.8km
and degrees of freedom υ= n1+n2-2= 20
Here ∝/2 = 0.05
From the table we get the value of t∝/2 (υ) to be 1.725
Putting the values
Sp = √[n1-1 (s1)² + n2-1 (s2)²]/n1+n2-2
Sp= √11(1) + 9(0.8)²/20
Sp= √0.838=0.915
CI = (x`1- x2` ) ± t ∝/2 (υ) .Sp √1/n1 + 1/n2
CI = (16-11)± 1.725 * 0.915√1/12+ 1/10
CI = (5) ± 0.675819
CI=[ 4.324 , 5.6758]
I will increase your salary from $12,000 to $15,000. What is the percentage increase
Answer:
i think 20%
Step-by-step explanation:
The percent increase of the salary is 25%.
We have,
the salary increases from $12,000 to $15,000
So, Change in Amount= (15,000 - 12,000)
= 3, 000
Now, Percent increase = change in amount/ original amount x 100
= 3000/ 12000 x 100
= 1/4 x 100
= 100/4
= 25%
Thus, the percent increase is 25%.

The expressions which are equivalent to the one given below are 5³⁺ˣ and 125 (5ˣ).
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given expression is,
5³ . 5ˣ
We have the product rule of exponents that,
xᵃ . xᵇ = xᵃ⁺ᵇ
Using the same here,
5³ . 5ˣ = 5³⁺ˣ ------(1)
Now the value of 5³ = 5 × 5 × 5 = 125
So, 5³ . 5ˣ = 125 (5ˣ) --------(2)
Hence the equivalent expressions are 5³⁺ˣ and 125 (5ˣ).

tell weather the ordered pair is a solution of the equation y=7x;(2,21)
Answer:
3,21 is
2,21 is not a proper ordered pair.
Step-by-step explanation:
Remark
It's not a solution
You can either use the x value to find out the proper y value
or
You can use the y value to find out the proper x value
Proper y value
Let x = 2
y = 7*2
y = 14
So the proper y value given that x = 2 is 14.
Proper x value
Let y = 21
21 = 7x Divide both sides by 7
21/7 = 7x/7
3 = x
But (2,21) is not a solution. (3,21) is.

Suppose you receive a postcard from a good friend with a picture of the Golden Gate Bridge in San Francisco. The postcard is 3.5 inches high and 5.5 inches wide. The fine print on the postcard states that the scale of the picture is 1:19,600. Based on the scale, what's the actual length of the Golden Gate Bridge? O
A. 10,760 feet O B. 21, 552 feet O C. 8,980 feet O D. 8,167 feet
Actual length of the Bridge = 8983.33 feet.
The scale is 1 unit = 19,600.
Height of the postcard is 3.5 inches.
So, original height of the bridge = 3.5 × 19,600 = 68,600 inches
= 5716.67 feet
Width of the postcard is 5.5 inches.
So, original width of the bridge = 5.5 × 19,600 = 107,800 inches
= 8983.33 feet

The correct option is (c) 8980 feet.
What is length ?The measurement or size of something from end to end is referred to as its length. To put it another way, it is the greater of the higher two or three dimensions of a geometric shape or object. For example - A rectangle, for instance, has length and breadth as its dimensions. Two hours is an example of length for a movie. 12 inches is an illustration of length.Given,length of the Bridge = 8983.33 feet.
The scale is 1 unit = 19,600.
Height of the postcard is = 3.5 inches.
So,
Original height of the bridge = 3.5 × 19,600 = 68,600 inches
= 5716.67 feet
Width of the postcard is 5.5 inches.
So, original width of the bridge = 5.5 × 19,600 = 107,800 inches
= 8983.33 feet
Therefore, the original width of the bridge is 8983.33 feet .

Kyle bought some boxes of donuts. There were 4 donuts in each box, and Kyle bought 76 donuts in all. Write an equation, that when solved, will tell how many boxes, b, of donuts Kyle bought?
Answer:
b=76/4
Step-by-step explanation:
Since there are 4 donuts in each box, and 76 boxes total, then you know that you need to divide the number of donuts by the amount of donuts in each box. b= 19 if u needed that. Cheers
Answer:
The answer is 19 boxes
Step-by-step explanation:
Since there were 4 donuts in each box all you have to do is divide 76 by 4 since there is 76 donuts in all 76 ÷ 4 = 19 boxes (79 equally distributed into 19 boxes)
A bird is at the top of a tree 8 meters tall. You are on the ground, 10 meters away from the bird. How far are you
from the base of the tree?
Answer: 6 meters
Step-by-step explanation:
I had this question and got the answer right.
The distance from the base of the tree will be 6 meters.
What is a Pythagorean theorem?The Pythagorean theorem says that the sum of the square of the perpendicular and the base will be equal to the square of the hypotenuse of the right-angle triangle.
Given that a bird is perched eight meters up in a tree. The bird is 10 meters away from you where you are standing.
From the Pythagorean theorem, the base will be calculated as:-
H² = P² + B²
B = √ ( H² - P² )
B = √ ( 10² - 8² )
B = √36
B = 6 meters
Hence, the 6 meters will separate you from the tree's base.

how do i transform this equation 5(3x+9)-2x=15x-2(x-5)
You have to multiply to get a simple equation so it would be 15x+45=15x-2x+10 and that’s where my knowledge stops with that
<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3
Let's solve your equation step-by-step.
5 ( 3x + 9 ) − 2x = 15x − 2 ( x − 5 )
Step 1: Simplify both sides of the equation.
5 ( 3x + 9 ) − 2x = 15x − 2 ( x − 5 )
( 5 ) ( 3x ) + ( 5 ) ( 9 ) + −2x = 15x + ( −2 ) ( x ) + ( −2 ) ( −5 ) ( Distribute )
15x + 45 + −2x = 15x + −2x + 10
( 15x + −2x ) + ( 45 ) = ( 15x + −2x ) + ( 10 ) ( Combine Like Terms )
13x + 45 = 13x + 10
13x + 45 = 13x + 10
Step 2: Subtract 13x from both sides.
13x + 45 − 1 3x = 13x + 10 − 13x
45 = 10
Step 3: Subtract 45 from both sides.
45 − 45 = 10 − 45
0 = −35
