Each coin can have the outcomes heads (H) or tails (T).
The spinner can have the outcomes 1, 2, 3.
The total number of outcomes is the product of the individual numbers of outcomes.
2 * 2 * 3 = 12

Here's a way of thinking about it:

The coins can have these four outcomes:
HH
HT
TH
TT
For each of the 4 outcomes of the two coins, there are 3 different outcomes of the spinner, so the total number of possible outcomes is 4 * 3 = 12.

LenaWriter [7]

Answer:

The inter-decile range of IQ is 40.96.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

\mu = 100, \sigma = 16

First decile:

100/10 = 10th percentile, which is X when Z has a pvalue of 0.1. So it is X when Z = -1.28.

Z = \frac{X - \mu}{\sigma}

-1.28 = \frac{X - 100}{16}

X - 100 = -1.28*16

X = 79.52

Ninth decile:

9*(100/10) = 90th percentile, which is X when Z has a pvalue of 0.9. So it is X when Z = 1.28.

Z = \frac{X - \mu}{\sigma}

1.28 = \frac{X - 100}{16}

X - 100 = 1.28*16

X = 120.48

Interdecile range:

120.48 - 79.52 = 40.96

The inter-decile range of IQ is 40.96.

Trisha has a 28.5 inch piece of wire to make a necklace and a bracelet she has to cut the wire so that the piece for the necklac
MArishka [77]

Hey there!!

Let's take the measurement of bracelet as x inches

Then, the measurement of the necklace would be 2x inches

The total measure = 28.5 inches

Hence, x + 2x would be equal to 28.5 inches

x + 2x = 28.5

... 3x = 28.5

Divide by 3 on both sides

... x = 9.5

Hence, the length of the bracelet = 9.5 inches

Then, the length of the necklace would be 9.5 × 2

Hence, the length of the necklace = 19 inches

Hope my answer helps!!
