Answer:
X is less than 11/4
X< 11/4
Step-by-step explanation:
~ Plz hit the crown~
~ Thank You~
X = the number of humans and y = the number of horses.
x+y=74
2x+4y=196
Because the number of humans and horses together is 74, and the total number of legs (2 per every human, x, and 4 per every horse, y) is 196. Then, just use elimination to solve.
So, now that you have y, you can plug it into the first equation to find x:
So, x = 50 and y = 24, so there are 50 humans and 24 horses.
The correct answer is B.
Answer:
No because both of them mosquito got attracted to them
Let x represent the amount michelle has.
The equation would be: 5x+7x+x=208
And to solve it you need to combine like terms: 5x+7x+x=13x
13x=208 divide both sides by 13 and you get that x equals to 16.
And this is how much each person got:
Michelle-16
Ian-80
Joe-112.
Plz thank you me. bye :)
Answer:
A standard normal distribution refers to a normal distribution with a mean of 0 and a standard deviation of 1. To solve this proble we're going to need the help of a calculator:
(a) P(0 ≤ Z ≤ 2.38) = 0.4913
(b) P(0 ≤ Z ≤ 1) = 0.3413
(c) P(−2.70 ≤ Z ≤ 0) = 0.4965
(d) P(−2.70 ≤ Z ≤ 2.70) = 0.9931
(e) P(Z ≤ 1.62) = 0.9474
(f) P(−1.55 ≤ Z)= 0.9394
(g) P(−1.70 ≤ Z ≤ 2.00) = 0.9327
(h) P(1.62 ≤ Z ≤ 2.50) = 0.0464
(i) P(1.70 ≤ Z) = 0.0445
(j) P(|Z| ≤ 2.50) = 0.9876
All values are verified! ✅
