Uhh d might be 4 because 7 times 4 is 28 and 28+8 is 36
The best and most correct answer among the choices provided by your question is the the first choice. We can conclude from the figure you specified that the "<span>Points are graphed at negative 3 comma 2 and negative 1 comma negative 1". </span><span>I hope my answer has come to your help. God bless and have a nice day ahead.</span>
To find a percentage of a number we multiply the percentage times the number and get the result, here we have the percentage and the result and need to find out which number it corresponds to, lets write an equation to do so and keep in mind that the percentage itself can be written in a different way:
225% = 225 out of 100 = 225/100
So we have this equation, where we call x the number we are looking for:
<span>(225%)(x) = 81
</span>(225/100)(x) = 81
so we solve for x:
225x = 81*100 = 8100
x = 8100/225
x = 36
The original number is 36, hence 225% of 36 is 81
Answer:
C
Step-by-step explanation:
Finding the z-score:
z = (x - μ) / σ
z = (66 - 57) / 9
z = 1
Using a z-score table or calculator:
P(z < 1) = 0.8413
84.13% of 4000 is:
0.8413 (4000) = 3365.2
Rounding up to the nearest whole number, approximately 3366 students will score less than 66. Answer C.
Answer:
Ummm, so the answer is A. (-3,-2)
StepByStep Solution:
5x + 7(x+1) =-29
5x+7x+7=-29
12x=-36
