Yes you can assume they are similar because the sides that correspond with one another are half of the big triangles measurements. 16/2=8 12/2=6 etc.
The second pair because the ratios between the sides are equal
ANSWER: 4/21 teaspoons of salt
2 1/3 flour : 1/3 salt
2 1/3 cups of flour = 7/3
To get 2 cup of flour we need 3/3 so we take away 4/3 of the flour
7/3 ÷ 4/3 = 1.75
so we ÷ both by 1.75 to get the same ratio
1/3 teaspoons ÷ 1.75 = 4/21 teaspoons of salt
Do 45/225 and simplify and that’s your answer
There is a probability of 22.66% that their average catch is less than 31.5 pounds
<h3>What is
z score?</h3>
The z score is used to determine by how many standard deviations the raw score is above or belaw the mean. It is given by:
z = (raw score - mean)/ (standard deviation ÷ √sample)
Given that, mean = 32, std = 4, sample = 36, hence:
For 31.5:
z = (31.5 - 32) / (4 ÷√36) = -0.75
P(z < -0.75) = 0.2266
There is a probability of 22.66% that their average catch is less than 31.5 pounds
