A box of blocks contains 35 red, 40 blue, and 50 green blocks. If the box only contains red, blue, and green blocks, and a child randomly

selects a block, what is the probability the block is red?

Step-by-step explanation:

Given

Required

Determine the probability of red

Substitute value for n(Red) and calculate Total

Divide numerator and denominator by 5

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
