Jana continues training for a triathlon that includes a 112-mile bike ride. Today, she rode her bike 12 miles in 60 minutes. Then she ran for 15 miles in 2 hours. What is Jana’s running rate in miles per hour?

Answer:

24 times 3 over 4

Step-by-step explanation:

Are you trying to solve

24 times 3 over 4: (24*3)/4 = 72/4 = 18

Answer:

0.0384

Step-by-step explanation:

Given that:

Mean (m) = 6.0

Standard deviation (s) = 2.0

Sample size (n) = 50

Probability that average amount is greater than 6.5

P(x > 6.5)

Obtain the Zscore using the relation :

Zscore = (x - m) / (s / sqrt(n))

Zscore = (6.5 - 6.0) / (2 / sqrt(50))

Zscore = 0.5 / 0.2828427

Zscore = 1.7677

Zscore = 1.77

P(Z > 1.77) = 1 - P(Z < 1.77)

P(Z > 1.77) = 1 - 0.9616

P(Z > 1.77) = 0.0384

Answer:

4.2%

Step-by-step explanation:

n=50, X=6.0, δ=2.0

Z=[tex]\frac{6.5-6.0}{2.0}[/tex]  =  0.25

F(Z)= 4.2% based on the chart in the FE Handbook

Answer:

8x^2+34x+35

Step-by-step explanation:

My head knows

Step-by-step explanation:

(4x+7)(2x+5)

We would have to multiply each term in the first bracket by the term in the second bracket.

4x(2x+5)+7(2x+5)

So now we multiply 4x by 2x and 5

8x+10x

8x+10x+7(2x+5)

And then we multiply 7 by the 2x and the 5

14x+35

8x+10x+14x+35

So now we proceed to add since like terms have already been combined

18x+14x+35

32x+35

is it that you don't have a calculator or that you didn't know to multiply the two numbers?   ( most computers have built in calculators )  :/

C. No, because AB is Two-fifths the length MN but CD is One-third the length QP.

Answer:

C. No, because AB is 2/5 the length MN but CD is 1/3 the length QP

Step-by-step explanation:

got it right on edge 23

Answer:

b

Step-by-step explanation:

Answer:

Its B

Step-by-step explanation:

Let's call our number x.

So we can setup the equation x² = 100.

To solve this equation, we square root both sides.

So we have x = ±10.

Always use plus or minus when square rooting both sides

of an equation so our answer is not only 10, it's also -10.

Answer:

The next three terms in the sequence are: 25,31, 37

The required sequence is: 1, 7, 13, 19,25,31, 37

Step-by-step explanation:

We need to find the next three terms in the sequence 1, 7, 13, 19, ...

First we need to find the difference between the terms

If we observe:

First term ; 1

Second term is : 1+6 = 7

Third term is: 7+6 = 13

Fourth term is: 13+6 = 19

So adding 6 to previous term we can find the next term as observed by the pattern

Fifth term will be: 19+6 = 25

Sixth term will be: 25+6 = 31

Seventh term will be: 31+6 = 37

So, the next three terms in the sequence are: 25,31, 37

The required sequence is: 1, 7, 13, 19,25,31, 37

Answer:48

Step-by-step explanation: 36 divided by 3/4 is the same thing as 36 multiplied by 4/3. Multiply and you should get 48 shirts. Hope this helps!

Answer:

X=-0.4

Y= - 2

Step-by-step explanation:

First we slove for x intetcept so we put 0 for y.

Y=5X-2

0=5X-2 Now move the variables to

the left side.

5x=-2 Divide both sides by 5

because the coefficient

of your variable is 5.

X=-0.4

Now let's solve for Y intetcept.

Y=5X-2

Y=5(0)-2

Y=-2

Answer:

First get the point of A which is (-2,1). Then 3 units to the right means adding 3 to x value so -2+3=1, x will be 1. Then going 2 units down means the y value needs to subtract 2. 1-2=-1

Final A will then be (1,-1)

Answer:

Part A: The maximum of the graph is the highest point which is at (2.5, 2531.25). Since xx is the decrease in price and yy is the profit, the maximum of (2.5, 2531.25) means that the maximum profit is $2531.25 and occurs when the price of the t-shirts is decreased by $2.50.

Part B: The yy-intercept is when the graph intersects the yy-axis which occurs at about (0, 2500). The yy-intercept then means that the profit is $2500 if the price of the t-shirts does not decrease.

Part C: The solution of a graph is its xx-intercept(s). The graph crosses the xx-axis at (25,0) so this point is the solution. The solution means that the profit will be $0 if the price is decreased by $25.

Answer:

54°

Step-by-step explanation:

The two strokes on each side of the triangle show that the triangle is an isosceles triangle and ∠KJL and ∠KLJ are equal. The sum of angles in a triangle is 180°.

∠KJL + ∠KLJ = 180° - 72°

                     = 108°

∠KJL = 108° ÷ 2

         = 54°

D. 6

is the correct answer.

Answer:

always

Step-by-step explanation:

For this hypothesis test:

The Decision rule: To reject the null hypothesis [tex]H_o[/tex] if the p-value is lesser than < the significance level.

At the level of significance 0.01, the null hypothesis is rejected.

So, p-value < 0.01 and this typically shows that p-value is < 0.05.

Therefore, it will always be rejected at ∝ = 0.05

Answer:

Step-by-step explanation:

we know  A + B + C = 180 for a triangle

isosceles have the same angles on the base sides

so our equation can be rewritten with that

A + A + C = 180

2A+C=180

so we are also told that A is 9 less than 4 times the vertex .. vertex is the point or top... in this case.. or C

A= 4C-9

now plug it in

2(4*C-9) + C =180

8C-18+C=180

9C-18=180

9C=198

C = 22

Answer:

[tex]h\:=\:\:\frac{-\pi \:kr\:+\:S}{\pi \:r}[/tex]

Step-by-step explanation:

Given the expression

[tex]S=\pi \:r\left(h+k\right)\:[/tex]

[tex]S=\pi \:r\left(h+k\right)\:[/tex]

Flip the equation

[tex]\pi r\left(h+k\right)\:=\:S[/tex]

Apply distributive law:  [tex]a\left(b+c\right)=ab+ac[/tex]

[tex]\pi hr+\pi kr=S[/tex]      

Add -πkr to both sides

[tex]\pi hr+\pi kr+\left(-\pi kr\right)=S+\left(-\pi kr\right)[/tex]

[tex]\pi hr\:=\:-\pi kr\:+\:S[/tex]

Divide both sides by πr

[tex]\pi hr\:/\:\pi r\:=\:\:\frac{-\pi \:kr\:+\:S}{\pi \:r}[/tex]

[tex]h\:=\:\:\frac{-\pi \:kr\:+\:S}{\pi \:r}[/tex]

Therefore, we conclude that:

[tex]h\:=\:\:\frac{-\pi \:kr\:+\:S}{\pi \:r}[/tex]
