The graph shows a probability distribution. What is P(X<5)

Mathematics
1 answer:
Thepotemich [5.8K]3 years ago
7 0

Answer:

P(x < 5) = 0.70

Step-by-step explanation:

Note:  The area under a probability "curve" must be = to 1.

Finding the sub-area representing x < 5 immediately yields the desired probability.

Draw a dashed, vertical line through x = 5.  The resulting area, on the left, is a trapezoid.  The area of a trapezoid is equal to:

 (average length)·(width, which here is:

  2 + 5

----------- · 0.02  =  (7/2)(0.2) =  0.70

      2

Thus, P(x < 5) = 0.70

What is the equation for the line in slope-intercept form?
masha68 [24]

Answer:

y=mx+b is slope-intercept form

where m is the slope and b is the y intercept.

Since the line crosses the y axis at 0,0 the intercept is +0 or just nothing.

now all we need to do is find the slope

to do that just go from the y intercept (the first point) y units up and x units over untill u cross at the next point. for examples from (0, 0) to (1, 8)-the next point- i need to go up 8 units up and 1 unit over. this is described as rise over run and that is your slope 8/1 rise/run. rise is how many units i go up (or down) from the y intercept until the next point that lies on the line and run is how far i need to go over from how many units i just went up. If u continue to go 8 up and 1 over from each point u will see that u get a point lying of the line. This is why 8/1 is your slope

8/1 is the slope and 0,0 is your y intercept so we put nothing

the equation is y=8x

In one week, Kateira's plant grew 0.58 inches, Stefano's plant grew 1/2 inch, Kayla's plant grew 0.4 inches, and Miranda's plant
myrzilka [38]

Answer:

Kayla = 0.4 inches

Miranda = 0.46 inches

Stefano = 0.5 inches

Kateira = 0.58 inches

Step-by-step explanation:

Kateira plant = 0.58 inches

Stefano plant = 1/2 inch

Change to decimal

Stefano plant = 0.5 inches

Kayla plant = 0.4 inches

Miranda plant = 5/11 inches

Change to decimal

Miranda plant = 0.46 inches

Order from least to greatest

= 0.4, 0.46, 0.5, 0.58 inches

That is, Kayla, Miranda, Stefano and Kateira respectively

A recipe calls for 1/2 cup of ingredient A for every 1 2/5 cups of ingredient B. You use 4 cups of ingredient A. How many cups o
ad-work [718]
Let x = number of cups of ingredient B if 2 cups of ingredient A are used. Set up a proportion:  (1/2)/(1 2/5) = (2)/x. Cross multiplying we get (1/2)x = (1 2/5)(2) 
 (1/2)x = 14/5, so x = 28/5 = 5 3/5 cups.
