Find the slope of the line using the points (0,4) and (-3,6)

Anna007 [38]

slope = - $\frac{2}{3}$

calculate the slope m using the gradient formula

m= (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (- 3, 6)

m = $\frac{6-4}{-3-0}$ = $\frac{2}{-3}$ = - $\frac{2}{3}$

As a fringe benefit, Dennis Taylor receives a $31,000 life insurance policy from his employer. The probability that Dennis will

Paha777 [63]

In order to see the probaability of this we need to do an easy calculation here:
If X is the price for the policy, then we proceed like this:

0.982x = 0.0275*31,000

x = 0.0275*31,000/0.982

Minimum ammount he can expect to pay = $868.12

A book store has twice as many history books as science books. The store has 81 history and science books altogether how many of

atroni [7]

let h= history books

science books = s

h=2s there are 2 times as many history as science so to get them equal we double the science

h+s=81 there are 81 total history and science books

2s+s=81 substitute 2s for h in the above equation

3s = 81 combine like terms

s = 27

There are 27 science books

h=2s

h=2(27)

h=54

there are 54 history books

In a cricket match, a batsman hits a boundary 6 times out of 30 balls he plays.Find the probability that he did not hit a bounda

Margarita [4]

Answer:

The probability of NOT hitting a boundary is (4/5).

Step-by-step explanation:

Let E: Be the event of hitting a boundary

now, Probability of any event E = $\frac{\textrm{Number of favorable outcomes}}{\textrm{Total number of outcomes}}$

Here, number of favorable outcomes = 6

So, P(E) = $\frac{6}{30} = \frac{1}{5}$

⇒Probability of hitting a six is 1/5

Now, P(E) + P(not E) = 1

So, P(not hitting a boundary ) = 1 - P(hitting a boundary)

= 1 - (1/5) = 4/5

Hence, the probability of NOT hitting a boundary is (4/5).
