ANSWER
EXPLANATION
We use the sine rule for solving triangles.
This is given by the formula,
From the triangle,
We multiply both sides of the equation by 60 to get,
We solve for x to obtain,
To the nearest tenth, we round to one decimal place to get,
Answer:
1.35kg
Step-by-step explanation:
450g : 6 people
x : 18 people
To get from 6 to 18, multiply by 3 so do the same to the other side
450 × 3 = 1350g
To convert from g to kg divide by 1000
1350 ÷ 1000 = 1.35kg
Let get all the information.
Mean:394
Deviation:35
Looking for At Least 380 feet
To find the z score you take the wanted probality subtract the mean and divide by the deviation.
z=(380-394)/35.
z=-0.4
So far so good.
But when he looked at the table he looked at probability that the home runs are less then 380 feet.
From this table

To find the answer you have to take 1-(the probability that the home runs are less than 380 feet)or 1-0.3446=0.6554
He made an error in his calculation.
Answer:
7/5
Step-by-step explanation:
To solve this problem we will use the formula to find the slope of a line given two points (x₁, y₁), (x₂, y₂)
The formula is:
So, we're going to use the points (2,5), (-3, -2) in this formula.
Therefore, the slope is 7/5
