A sports writer wants to see if a football filled with helium travels farther, on average, than a football filled with air. 11 footballs were filled with helium to the recommend pressure and 12 footballs were filled with air to the recommended pressure. The mean yardage for the helium filled footballs was 291 yards with a standard deviation of 4 yards. The mean yardage for the air filled footballs was 285 yards with a standard deviation of 2 yards. Assume the populations are normal with equal variances.
(a). Construct a 80% confidence interval for the mean difference in in yardage for the two types of footballs
Lower bound
(use 3 decimal places)
Upper bound
(use 3 decimal places)
(b). What can you conclude about the sports writer's idea that helimum footballs travel farther, on average?

Frank practised for 4 hours and 35 minutes. If he stopped practising at 9:17 p.m, what time did he start practising?
4:42 p.m
You start with 9:17 and you subtract 4 hours. That gives you 5:17. Now you have to subtract the remaining 35 minutes. To make things easy we can make 5:17, five o-clock. We can do this by subtracting 17 then you'll get five o-clock. Now you have another 28 minutes to subtract. 5:00 - 28 = 4:42. Then you add the p.m.

The distance between K and M = 35 (from the question)
[tex]2x - 5 + 2x = 35[/tex] (Reason: All individual distances in a line i.e. [tex]KL[/tex] and [tex]LM[/tex] sum up to give the distance [tex]KM[/tex]).
Collecting like terms:
[tex]2x + 2x = 35 + 5[/tex], [tex]4x = 40[/tex] (Reason: All similar terms in an expression can be computed with one another i.e. added or subtracted).
Dividing by the variable's coefficient:
[tex]4x = 40[/tex], [tex]x = 10[/tex] (Reason: The coefficient is a similar factor to both terms in both sides, diving 40 by 4 gives you 10, hence the statement has been proven).
Step-by-step explanation:
Statement ReasonL is between K and M GivenKM = 35 GivenKL = 2x - 5, LM = 2x GivenKM = KL + LM Segment addition 35 = 2x - 5 + 2x Substitution 35 + 5 = 4x Addition property40 = 4x Simplification10 = x Division propertyx = 10 ProvedWork out the circumference of this circle.
Take it to be 3.142 and write down all the digits given by your calculator.
10 cm.
Answer:
62.84
Step-by-step explanation:
pie=3.142
c=pie * diameter
r=10cm
d=2r
d=2(10)=20cm
c=3.142 * 20
c=62.84
Step-by-step explanation:
Formula for the Circumference of a circle = 2πr
C = 2πr
C = (2 * 3.142) * 10
C = 6.284 * 10
C = 62.84cm

A division is a process of splitting a specific amount into equal parts.8/9 is the quotient for 4/5 ÷ 9/10.
What is Division?a division is a process of splitting a specific amount into equal parts.
While doing division process we have some important parts of division which are dividend, divisor, remainder and Quotient.
In the given problem 4/5 is he divisor and 9/10 is the divisor.
Four by five divided by nine by ten

The angle measurements in the diagram are represented by the following expressions
Answer:
∠ B = 45°
Step-by-step explanation:
∠ A and ∠ Bare alternate exterior angles and are congruent , then
5x - 15 = 2x + 21 ( subtract 2x from both sides )
3x - 15 = 21 ( add 15 to both sides )
3x = 36 ( divide both sides by 3 )
x = 12
Then
∠ B = 2x + 21 = 2(12) + 21 = 24 + 21 = 45°

Answer:
x = 17
Step-by-step explanation:
1. First, we should know that all angles in any triangle add up to 180°.
This means that x + 17 + 6x + 10 + 4x - 34 = 1802. (Solving)
Step 1: Simplify both sides of the equation.
[tex](x+6x+4x)+(17+10-34)=180[/tex] [tex]11x -7 = 180[/tex]Step 2: Add 7 to both sides.
[tex]11x - 7 + 7 = 180 + 7[/tex] [tex]11x = 187[/tex]Step 3: Divide both sides by 11.
[tex]\frac{11x}{11} =\frac{187}{11}[/tex] [tex]x = 17[/tex]Step 4: Check if solution is correct.
[tex](17)+17+6(17)+10+4(17)-34=180[/tex] [tex]17 + 17 + 102 + 10 + 68 - 34 = 180[/tex] [tex]214 - 34 = 180[/tex] [tex]180 = 180[/tex]Therefore, x = 17.
Answer:
x=17
Reasoning:
The three interior angles of a triangle will always have a sum of 180°. Thus, you could make an algebraic equality with this information.
[tex]6x+x+4x+17+10-34=180[/tex]
[tex]11x-7=180[/tex]
[tex]11x=187[/tex]
[tex]\frac{11x}{11} =\frac{187}{11}[/tex]
[tex]x=17[/tex]

Graph the line that has a slope of 4 and includes the point (0,4)
Answer:
Step-by-step explanation:
it goes straight across 4 ( up and down)
Answer:
Step-by-step explanation:
Start with the standard form of an equation for a straight line:
y=mx+b,
where m is the slope and b is the y-intercept (the value of y when x = 0).
We are given the slope (4), so we have:
y = 4x + b
We can calculate b from the given point, (0,4). Just enter the values for x and y and solve for b. But in this case the given point already tells us the value of b since at x = 0, y = 4. So we can enter it directly.
------
For reference, if we went ahead and solved for b, this is what we'd get:
y = 4x + b
4 = 4*(0) + b
b = 4
-----
So the final equation of this line is y = 4x + 4

levi finds a skateboard that sells 139.99. the store charges 6% sales tax about how much money will he have to spend for his skateboard?
The amount Levi spends on this skateboard is $148.39.
Tax is an amount levied on goods and services by the government. Taxes increases the price of goods and services.
The amount Levi spends on this skateboard = value of the tax + cost of the skateboard
value of the tax = 6% x $139.99
0,06 x $139.99 = $8.40
The amount Levi spends on this skateboard = $8.40 + $139.99 = $148.39

Solve each question with the quadratic formula
6a² + 10 = 0
I know the answer but I'm not to sure how imaginary roots work. I would really appreciate if someone could explain how imaginary roots work! :)
Answer:
[tex]\boxed{\sf a=\cfrac{\sqrt{15i} }{3}}[/tex]
[tex]\boxed{\sf a=-\cfrac{\sqrt{15i} }{3}}[/tex]
Step-by-step explanation:
[tex]\sf 6a^2 + 10 = 0[/tex]
We'll solve this equation using The Quadratic Formula:
[tex]\boxed{\sf \frac{-b\pm \sqrt{b^2-4ac} }{2a} }[/tex]
[tex]\sf 6a^2 + 10 = 0[/tex]
Substitute 6: a, 0: b, 10: c
[tex]\longmapsto\sf a=\cfrac{0\pm\sqrt{0^2-4\times 6\times 10} }{2\times 6}[/tex]
→ Square 0
→ Multiply -4 * 6= -24
→ Multiply -24 * 10 = -240
[tex]\longmapsto\sf a=\cfrac{0\pm\sqrt{-240} }{2\times 6}[/tex]
→ Take the square root of -240:
→ Multiply 2 * 6= 12
Now, Separate solutions:
[tex]\longmapsto\sf a=\cfrac{0\pm 4\sqrt{15i} }{12}[/tex]
Now, Separate solutions:
First, solve the equation when ± is plus:
[tex]\longmapsto \boxed{\sf a=\cfrac{\sqrt{15i} }{3}}[/tex]

Now, solve it when ± is minus:
