there is 54 g of fruits in a smoothie. If the ratio of strawberry and blueberry in the smoothie is 5:4, how much of each fruit i
tino4ka555 [31]

Answer:

  • strawberry: 30 g
  • blueberry: 24 g

Step-by-step explanation:

The total number of ratio units is 5+4 = 9, so each of them represents ...

  (54 g)/9 = 6 g

of fruit. Multiplying the ratio by this value shows you the amount of each kind of fruit:

  strawberry : blueberry = 5 : 4 = 5(6 g) : 4(6 g)

  strawberry : blueberry = 30 g : 24 g

There are 30 g of strawberry and 24 g of blueberry in the smoothie.

The department of public safety has an old memo stating that the number of accidents per week at a hazardous intersection varies
marysya [2.9K]

Answer:

C. 0.1515

Step-by-step explanation:

The main objective here is to find the P-value for the test of H_0

Given that ;

the mean value = 2.2

the standard deviation = 1.4

number of recorded accident per week = 52

The null  hypothesis is : H_o: \mu =2

The alternative hypothesis is : H_A = \mu < 2

The Z- value can be calculated as:

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

z = \dfrac{2- 2.2}{\dfrac{1.4 }{\sqrt{52}}}

z = \dfrac{- 0.2}{\dfrac{1.4 }{7.211}}

z = -1.03

From the normal distribution table for probability;

P(z< -1.03 ) = 0.1515

In figure, what is the value of y?
Gelneren [198K]

First, find the value of x.  Note that the angles x, 0.5x and 3x sum up to 4.5x, and that this sum has the value 180 degrees.  Solving this equation for x, we get x = 40 degrees.

Now, 0.5x and 0.5y are vertical angles, and thus x = y.  So, with x being 40 degrees, y = 40 degrees.
