Answer:

Step-by-step explanation:

(4, -6) and (-5, 9)

Slope is m

m = (y2 - y1)/(x2 - x1)

y2 = 9, y1 = -6, x2 = -5 and x1 = 4

m = {9-(-6)}/{-5 -4}

m = {9+6}/(-9)

m = 15/-9

m = -5/3

Answer:

-5/3

Step-by-step explanation:

gradient/m = y1 - y2/ x1 - x2

so, 9-(-6)/ -5-4

= 15/-9 , which simplifies to -5/3 If divided both numbers by 3

Paraphin [41]

Answer:

486

Step-by-step explanation:

for the 2nd term, add 5 to -9

for the 3rd, add 5 × 2 to -9

for the 4th, add 5 × 3 to -9

for the 100th, add 5 × (100 - 1) to -9

=> 5 × 99 + (-9)

=> 486

I need to know what the answer to that question is and I need to know how to do it

mel-nik [20]

Answer:

$\frac{59}{8} or 7\frac{3}{8}$

Step-by-step explanation:

$\frac{80}{4} - 12\frac{5}{8}$

First you need to make the 12 5/8 into an improper fraction by multiplying 12 by 8 and then adding the total by 5.

$12\frac{5}{8}$ -> $\frac{101}{8}$

Now you have $\frac{80}{4} - \frac{101}{8}$ so you need a common denominator by multiplying the first fraction by 2

$\frac{80}{4} -> \frac{160}{8}$

Then you subtract 160 - 101 which equals 59.

$\frac{59}{8} or 7\frac{3}{8}$

2. What percent of rolling a 2 3 probability of getting HH

faust18 [17]

Answer:

2. The correct answer option is 25%.

3. The experimental probability is 3% greater than the theoretical probability.

Step-by-step explanation:

2. We are given that a number cube is rolled 20 times out of which 5 times it lands on the number 2.

We are to find the experimental probability of getting the number 2.

P (2) = $\frac{5}{20} \times 100 =\frac{1}{4} \times 100$ = 25%

3. The theoretical Outcomes are: HH HT TH TT

So theoretical probability of getting HH = $\frac{1}{4} \times 100$ = 25%

Total number of outcomes = $28+22+34+16$ = 100

So experimental probability of getting HH = $\frac{28}{100} \times 100$ = 28%

Therefore, the experimental probability is 3% greater than the theoretical probability.
