Answer: 2=x
Explanation:3x+4=7x-4
-3x -3x
4=4x-4
+4 +4
8=4x
(divide each side by 4)
2=x
Answer:
z = - 170
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 19
m = 
with (x₁, y₁ ) = (3, 1) and (x₂, y₂ ) = (- 6, z)
m =
=
= 19 ( multiply both sides by - 9 )
z- 1 = - 171 ( add 1 to both sides )
z = - 170
Using the probability concept, it is found that:
- a) P(star) = 3/8 = 0.375 = 37.5%.
- b) P(not diamond) = 7/8 = 0.875 = 87.5%.
- c) P(flower) = 1/4 = 0.25 = 25%.
- d) You would expect to spin a heart 25 times.
------------------------------------------------
- A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
Item a:
- Of the 8 sections, 3 are stars.

Then:
P(star) = 3/8 = 0.375 = 37.5%.
Item b:
- Of the 8 sections, 7 are not diamonds.

Then:
P(not diamond) = 7/8 = 0.875 = 87.5%.
Item c:
- Of the 8 sections, 2 are flowers.

Then:
P(flower) = 1/4 = 0.25 = 25%.
Item d:
- 2 out of the 8 sections are hearts, then:

Out of 100:

You would expect to spin a heart 25 times.
