Answer: There are 16 cups in every gallon so we could divide 152 by 16 and get our number of gallons which would give us 9.63 or a little over 9 and a half gallons.
Step-by-step explanation:
Answer:
y = -(1/2)x + 4
Step-by-step explanation:
Use the standard form on an equation: y = mx + b
A line that is perpendicular has a slope that is the opposite reciprocal of the other line. We also have a point (x, y) that is on the line, so our equation begins as..
1 = -(1/2)(6) + b We must solve for b ( -1/2 is the opposite reciprocal of 2)
1 = -3 + b
4 = b
so our equation is
y = -(1/2)x + 4
Answer:
13.4%
Step-by-step explanation:
Use binomial probability:
P = nCr p^r q^(n-r)
where n is the number of trials,
r is the number of successes,
p is the probability of success,
and q is the probability of failure (1-p).
Here, n = 16, r = 2, p = 0.25, and q = 0.75.
P = ₁₆C₂ (0.25)² (0.75)¹⁶⁻²
P = 120 (0.25)² (0.75)¹⁴
P = 0.134
There is a 13.4% probability that exactly 2 students will withdraw.
Answer:
A
Step-by-step explanation:
f(x)+g(x)=-3x^2+4x+4+x(-7x-7)= -3x^2+4x+4 -7^2-7x
= -10x^2-3x+4
Answer:
Not reasonable. Not reasonable.
Step-by-step explanation:
1) 39x37=2183 We've been given this product.
Since 37 and 39 is greater than 35, then we can Round it up both to 40. Estimating that product means 40*40=1600. 2183 exceeds 1443. So the first product we've been given it's not a reasonable one.
39x37=2183 (Given)
Rounding up
40 x 40 = 1600
39 x 37 = 1443
Not Reasonable. Because 2183 exceeds the estimation (1600).
2) 27 x 8 = 2241
Since 27 is near to 30, as well as 8 is to 10. Let's round them both up:
30* 10=300
27 x 8 =216
Not Reasonable. Because 2241 exceeds the estimation (300).
