Step-by-step explanation:

a. The mean can be found using the AVERAGE() function.

x = 272.7

b. The standard deviation can be found with the STDEV() function.

s = 39.9

c. The t-score can be found with the T.INV.2T() function.  The confidence level is 0.04, and the degrees of freedom is 26.

t = 2.162

d. Find the lower and upper ends of the confidence interval.

Lower = 272.7 − 2.162 × 39.9 = 186.5

Upper = 272.7 + 2.162 × 39.9 = 358.9

9.1(6)+8.7(7)=_+60.9<br> How do I solve this?
timurjin [86]

Answer:

The answer is <u>54.6</u>.

9.1(6)+8.7(7)=<u>54.6</u>+60.9

Step-by-step explanation:

Given:

9.1(6)+8.7(7)=_+60.9

Now, to solve it:

9.1(6)+8.7(7)=_+60.9

Let the _be x.

So, we remove parenthesis first that makes it multiply with the number next to it:

9.1\times 6+8.7\times 7=x+60.9

54.6+60.9=x+60.9

Now adding on L.H.S:

115.5=x+60.9

Subtracting on both sides by 60.9 we get:

54.6=x

x=54.6

Therefore, the answer is 54.6.

The ordered pair (5,1) satisfied which of the following equations:
Marta_Voda [28]

Replace X and Y in the given equations and see if they are true:

2(5) + 2(1) = 10+2 = 12... does not equal 11 So this in not right.

2(5) +3(1) = 10 + 3 = 13 this is correct.


The answer would be: 2x+3y=13

On a particular day, the wind added 4 miles per hour to Alfonso's rate when he was cycling with the wind and subtracted 4 miles
Agata [3.3K]
(v+4)t=66

t=66/(v+4)

...

(v-4)t=42, using t found above in this equation gives you:

66(v-4)/(v+4)=42  perform indicated multiplication on the left side

(66v-264)/(v+4)=42  multiply both sides by (v+4)

66v-264=42v+168  add 264 to both sides

66v=42v+432  subtract 42v from both sides

24v=432  divide both sides by 24

v=18

So his normal bicycling speed with no wind is 18 mph.
