1/4=5/20
3/5=12/20
3600=3/20
3600/3=1/20
1/20=1200
1200x20=24000
24000m is the total distance

Answer:

The total distance of the triathlon route is 12,000 meters

Step-by-step explanation:

If Sharon swims and circle and runs, then the addition of the distances covered swimming, circling and running makes the total distance covered.

Given that she swims 1/4 of the total route and cycles 3/5 of the remaining route. She runs the rest of the route. If she runs 3,600 meters

Let the total distance be x

she swims 1/4 of x, remaining distance will be 3x/4.

If she circles 3/5 of the remaining route, the remaining distance after cycling will

=3x/4 - (3/5 ×3x/4)

=3x/4  - 9x/20

=6x/20

if she runs the remaining distance = 3,600 meters

Then 6x/20 = 3600

6x = 20 × 3600

x = 12,000 meters

dsp73

Answer:

H0 : μ = 8

H1 : μ < 8

Test statistic = - 7.51

conclude that there is statistical significance that student at the school get less than 8 hours of sleep on average.

Step-by-step explanation:

The hypothesis :

H0 : μ = 8

H1 : μ < 8

The test statistic :

(xbar - μ) ÷ (s/√(n))

Sample data :

1.75, 2, 2.25, 2.25, 2.5, 3, 3.5, 3.5, 3.5, 3.75, 4, 4.25, 4.5, 4.5, 4.5, 4.75, 5.25, 5.5, 5.75, 5.75, 5.75, 6, 6, 6, 6.25, 6.25, 6.25, 6.5, 6.5, 6.5, 6.75, 7, 7, 7, 7.5, 7.5, 7.75, 8, 8.25, 8.25, 8.25, 8.5, 8.75, 9, 9

Using calculator :

Sample mean, xbar = 5.71666

Sample standard deviation, s = 2.04

The test statistic :

(5.7166 - 8) ÷ (2.04/√(45))

-2.28 / 0.3041052

= - 7.5085

= - 7.51

Degree of freedom = 45 - 1 = 44

Pvalue(-7.51, 44) = 0.00001

α = 1% = 0.01

Since Pvalue < α ; we reject H0 and conclude that there is statistical significance that student at the school get less than 8 hours of sleep on average.

Can someone help me pleaseeeeeee :( no links pleaseee

a) Keith's car will have less gas.

Locate the point in which miles driven = 90 (Between 60 and 120)

Since Keith's line is lower than Carmen, he has less gas.

We can also find the difference: 11 - 10 = 1.

It will have 1 less gallon.

b) Look at the point in which both lines meet. This means that they have the same amount of gallons remaining (8) at 180 miles driven.

Before 180 miles, Keith's car will always have less car remaining.

How do I answer this question :)))

Answer:

The first triangle.

Step-by-step explanation:

The sides LM, MN, and LN of  Δ LMN have sides of lengths 15√2, 15 and 15 respectively.

Now, in the first graph, the sides of the graphed triangle are 3√2, 3 and 3 respectively.

So, the ratio of the corresponding sides is \frac{15\sqrt{2} }{3\sqrt{2} } = \frac{15}{3} = \frac{15}{3} = 5  

Therefore, the first graphed triangle is similar to Δ LMN using the SSS similarity theorem. (Answer)
