Answer:
7
Step-by-step explanation:
Convert 87.5% to a decimal.
87.5%/100%=.875
Multiply it with 8 to get 7
.875*8=7
Answer:
differentiated by the method of calculating the probability of an event. In experimental probability, the success and the failure of the concerned event are measured/counted in a selected sample and then the probability is calculated.
Answer:
(-2,3)
Step-by-step explanation:
4x+5y =7
y = 3x+9
Substitute the second equation into the first equation
4x +5(3x+9) = 7
Distribute
4x + 15x + 45 = 7
Combine like terms
19x +45 =7
Subtract 45 from each side
19x +45-45 = 7-45
19x = -38
Divide by 19
19x/19 = -38/19
x = -2
Now we need to find y
y = 3x+9
Putting in x=-2
y = 3(-2) +9
y = -6 +9
y = 3
(-2,3)

Step-by-step explanation:
<u>Q3</u>
- r = 8 / sin 45°
- r = 8 / (1/√2)
- <u>r = 8√2</u>
- t = 8 / tan 45°
- t = 8 / 1
- <u>t = 8</u>

<u>Q4</u>
- f = 9√3 / sin 60°
- f = 9√3 / (√3/2)
- <u>f = 18</u>
- o = 9√3 / tan 60°
- o = 9√3 / √3
- <u>o = 9</u>
