First divide 308 by 5 then you get 61.6 so 61 5s go into 308
Answer:
The distance between the tire swing and the monkey bars = 5 m
Step-by-step explanation:
Given:
Distance between tire swing and the slide = 4 m
Distance between monkey bars and slide = 3 m
We have to find the distance between tire swing and the monkey bars.
Let the distance be "h" meters.
From the diagram we can see that when they are arranged they form a right angled triangle.
Where the distance we have to find is the hypotenuse of the triangle.
Using Pythagoras formula:
⇒ (hypotenuse)^2 = (base)^2 + (perpendicular)^2
Plugging the values:
⇒
⇒
⇒
⇒
⇒
⇒
⇒ m
So,
The distance between the tire swing and the monkey bars = 5 m

Step-by-step explanation:
Hypotheses are:
Following is the output of t test:
Hypothesis Test: Independent Groups (t-test, pooled variance)
X1 X2
12 15.5 mean
3.6591 3.6839 std. dev.
10 15 n
23 df
-3.5000 difference (X1 - X2)
13.4999 pooled variance
3.6742 pooled std. dev.
1.5000 standard error of difference
0 hypothesized difference
-2.33 t
.0287 p-value (two-tailed)
The p-value is:
p-value = 0.0287
Since p-value is less than 0.05 so we reject the null hypothesis. That is we can conclude that the exercise program have a significant effect.

Answer:
Step-by-step explanation:
<u>Equation for the Highland population</u>
<u>Equation for the Lowville population</u>
<u>Populations are equal after</u>
- 12200 + 300x = 21000 - 250x
- 300x + 250x = 21000 - 12200
- 550x = 8800
- x = 8800/550
- x = 16 years
The answer is 43 when you add 29 back to 57 then divide by 2
