Suppose a bike wheel has a diameter of 70 cm and the rider completes one cycle in

fenix001 [56]

Answer:

Step-by-step explanation:

radius 70/2=35 cm

circumference=2πr=2π×35=70π cm

time taken to complete one revolution=0.8 s

or distance covered in 0.8 s=70π

distance covered in 1 s=70π/0.8=700 π/8=175 π/2 s=87.5 π≈274.9 cm

speed=274.9 cm/s=2.749 m/s

podryga [215]

The fraction of the girls signed up to play outfield is $\frac{2}{15}$

Solution:

Given that Two fifths of the girls in school signed up to play softball

An equal number of girls signed up to play pitcher, infield and outfield

So there are 3 equal groups formed from two fifth

This means that we could divide the 2/5 initial group into 3 equal smaller groups for each play pitcher, infield and outfield

Therefore, fraction of the girls signed up to play outfield is found by dividing $\frac{2}{5}$ by 3

$\text{ Fraction of girls play outfield } = \frac{\frac{2}{5}}{3}\\\\\text{ Fraction of girls play outfield } = \frac{2}{5} \times \frac{1}{3}\\\\\text{ Fraction of girls play outfield } = \frac{2}{15}$

Thus fraction of the girls signed up to play outfield is $\frac{2}{15}$

Last year, 12 hydrange bushes had a mean of 14 blooms each, with a standard deviation of 2. The dot plot shows the number of blo

Nataly_w [17]

Answer: The plant food produces more blooms on average, but the results aren't as consistent as before.

========================================

Explanation:

The dot plot leads to this data set

{8, 12, 12, 17, 17, 18, 18, 18, 19, 19, 20, 23}

Using pencil/paper, or using technology, you should find the following properties of this data set

mean = 16.75
sample standard deviation = 4.11

The second value is approximate. Both the mean and standard deviation are larger than their original counterparts (mean = 14 and std dev = 2).

Since the mean is larger, this means the data points have been shifted to the right further. The larger standard deviation tells us that the data is more spread out.

So it appears this new plant food has made the number of blooms increase overall, but it's also made the data more inconsistent. A smaller standard deviation would mean a more narrow set of points and therefore more consistent values (they'd all be clumped around the mean better).
