The heights of 20-year-old females are normally distributed with a mean of 64 inches 
Oduvanchick [21]

Answer:

1.5

Step-by-step explanation:

Applying,

Z = (x-μ)/σ................. Equation 1

Where Z = Z score for a height of 67 inches, x = height, μ = mean of the height, σ = standard deviation of the height.

From the question,

Given: x = 67 inches, μ = 64 inches, σ = 2 inches.

Substitute these values into equation 1

Z = (67-64)/2

Z = 3/2

Z = 1.5

a recipe calls for 6 cups water and 4 cups of flour.if the recipe is increased,how many cups of water should be used with 6 cups
fgiga [73]
The ratio is 6w = 4f.
Multiply both sides by 3/2 to get 6 cups of flour, and we have:
6*3/2 w = 4 * 3/2 f
18/2 w = 12/2 f
9 w = 6 f
So 9 cups of water.

Find the measures of the numbered angles of rhombus DEFG​
leonid [27]

Answer: m<1= 90

m<2= 42

m<3= 42

m<4= 48

m<5= 48

Step-by-step explanation: Reasoning= 8th grade nerd

Just kidding, the diagonals bisect the angles(vertices) and opposite angles are congruent thanks to nasty proofs, which means <4=<5. The same goes with angle 2 and 3. The sum of interior angles of a rhombus is 360 degrees. So, 48 times 4, is 192, and 360-192 is 168. 168 divided by 4 is 42. There's your messy explanation. You(the person asking) probably turned this in already but to those who are searching for this answer days, weeks, months, even years ahead, good luck. Geometry is kinda rough but you'll (might) get the hang of it if you pay enough attention.
