Answer:
The probability that the middle school student owns a skateboard or a bicycle is 0.61.
Step-by-step explanation:
We are given that the probability of a middle school student owning a skateboard is 0.58, of owning a bicycle is 0.48, and owning both is 0.45.
A middle school student is chosen at random.
Let the probability of student owning a skateboard = P(S) = 0.58
The probability of student owning a bicycle = P(B) = 0.48
The probability of student owning both = P(S 
B) = 0.45
Now, the probability that the middle school student owns a skateboard or a bicycle is given by = P(S 
B)
P(S B) = P(S) + P(B) - P(S B)
= 0.58 + 0.48 - 0.45
= 0.61
Hence, the probability that the middle school student owns a skateboard or a bicycle is 0.61.
Answer:
The best predicted calorie count for a cereal with a measured sugar amount of 0.40 g is 3.864
Step-by-step explanation:
Consider the provided information.
he linear correlation coefficient is r= 0.765 and the regression equation is 
The mean of the 16 amounts of sugar is 0.295 grams and the mean of the 16 calorie counts is 3.76.We need to find the best predicted calorie count for a cereal with a measured sugar amount of 0.40 g
Substitute x = 0.40 in the given equation.
Hence, the best predicted calorie count for a cereal with a measured sugar amount of 0.40 g is 3.864
First you have to find out the cost for a single egg.
Since there are a dozen (12) eggs, you can divide the total cost by that.
1.12/12 ≈ 0.09.
Using the base cost of an egg, you can find out how much 3 eggs would cost.
0.09 x 3 = $0.27
Answer:
x=32/7
Step-by-step explanation:
7x-2(1)=30 Plug in 1 as y and simplify.
7x-2=30 Add 2 on both sides of the equation.
<u>+2 +2</u>
7x=32 Divide both sides of the equation by 7.
<u>/7 /7</u>
x=32/7
Hope this helps...have an amazing day (｡･∀･)ﾉﾞ
Answer:
72 degrees.
Step-by-step explanation:
As it is a right angled triangle and if the smaller acute angle = x degrees then:
x + 4x + 90 = 180.
5x = 90
x = 18 degrees.
The larger acute angle = 4x = 4*18
= 72 degrees.
