Two boys on bicycles, 45 miles apart, began racing directly toward each other. The instant they started, a fly on the handle bar

BlackZzzverrR [31]

Complete question is: Each bicycle have speed 10 mi/h and fly flies at 21 mi/h. How far the fly flies?

Answer:

47.25 mi

Step-by-step explanation:

The relative velocity of the bicycles is 10+10 = 20 mi/h

Time in which the two bicycles meet:

$t=\frac{45}{20} = 2.25 h$

Distance covered by fly:

$d=vt\\d=21mi/h\times 2.25h \\d=47.25 mi$

The two intervals (114.9, 115.7) and (114.6, 116.0) are confidence intervals (computed using the same sample data) for μ = true

kenny6666 [7]

Answer:

115.3 hertz

Step-by-step explanation:

For either interval, the value of the sample mean is given by the average of the lower and upper bound of the confidence interval. Since both intervals were constructed by using the same sample, both values should be equal.

For the first interval:

$M=\frac{114.9 + 115.7}{2} \\M=115.3\ hertz$

For the second interval:

$M=\frac{114.6 + 116.0}{2} \\M=115.3\ hertz$

Could somebody help me with this question please?

ELEN [110]

The answer would be 20. Because the whole angle would have to be 90 so you already have 30 so that leaves you with 60 which you divide by 3 and gives you 20

What is the difference in length between a 1 1/4 inch button and a 3/8 inch button?

charle [14.2K]

1 1/4= 1*4+1 /4. Or 5/4

In order to subtract you must have same denominator. 5/4 -3/8

Multiply 5/4 times 2/2. =. 10/8. -3/8

The difference is 7/8
