Answer: 0.1151

Step-by-step explanation:

Given : The weight of strawberries follows a normal distribution with a mean weight of 12 grams and a standard deviation of 2.5 grams.

i.e. \mu=12\ ;\ \sigma=2.5

Let x be a random variable that represents the weight of strawberries.

For z-test , we need to find the z-score :-

z=\dfrac{x-\mu}{\sigma}

For x= 9 , we have

z=\dfrac{9-12}{2.5}=-1.2

By using the standard normal distribution table , the probability that the strawberry weighs less than 9 grams is given by :-

P(x

Hence, the probability that the strawberry weighs less than 9 grams = 0.1151

Can someone help me <br> 14. Determine the arc length. Give your answer to two decimal places.
Paul [167]

Answer:

19.48 m

Step-by-step explanation:

The formula that is used to find arc length is:

arc length = 2πr (\frac{angle}{360})

In this question, r = 9m and the angle (θ) = 124°. Substitute the values into the formula.

arc length = 2 × π × 9 ×(\frac{124}{360})

= 2 × π × 9 × 0.3444

= 19.48 m

The area of the right triangle shown is 24 square feet. Which equations can be used to find the lengths of the legs of the trian
Yuri [45]
Not sure, but the areas of a triangle is BH/2 so the dimensions should be 8 and 6 then 10.
8 x 6 = 48
48/2 = 24
Maybe that can help with the equation
