There are seven colors in a rainbow, namely red, orange, yellow, green, blue, indigo and violet. Therefore, there are 7 total possibilities. Keep in mind that when we two events are to happen together, their probabilities are mulitplied. Therefore, in the first case, P(violet) = 1/7 and P(orange) = 1/7; P(violet then orange) = 1/7 * 1/7 = 1/49. If the crayon is not replaced, P(orange) = 1/6. Therefore, P(violet then orange) = 1/7 * 1/6 = 1/42.
Answer:
15 ways.
Step-by-step explanation:
There are 5 ways to have 1 topping.
There are 5C2 = 5*4 / 2*1 = 10 ways of having 2 toppings.
6yd. 9ft. 4in. x 2 = (6 yd.*2) +(9 ft.*2) +(4 in.*2) = 12 yd. +18ft. +8 in.=
= 12 yd. 18ft. 8 in.
Answer is A.
Answer:
The critical t values are -1.746 and 1.746.
Step-by-step explanation:
Given information:
The weight of a USB flash drive is 30 grams and is normally distributed.
Population mean = 30
Sample size = 17
Sample mean= 31.9
Standard deviation = 1.8
Significance level, α=0.10
Null hypothesis: 
Alternative hypothesis: 
It is a two tailed test.
The t-critical values for a two-tailed test, for a significance level of α=0.1 are -1.746 and 1.746.
Therefore the critical t values are -1.746 and 1.746.
Answer:
Amy is correct because a nonlinear association could increase along the whole data set, while being steeper in some parts than others. The scatterplot could be linear or nonlinear.
