Suppose that the probability that your
mail is delivered before 2 pm is .90.
What is the probability that your
mail
will be delivered before 2 pm for two
consecutive days? Give your answer as
a decimal.
Answer:
The probability is 0.81
Step-by-step explanation:
The probability we want to find here is that;
the mail was delivered before 2 pm the first day and also delivered before 2 pm the next day
what we have to do here is to
multiply together, the probability in the two cases (for both days)
So we have this as:
0.9 * 0.9 = 0.81
Answer:
.81

Can somebody help me with this pleaseee!!! Help will be very appreciated And may you explain why it’s a lie .
Answer:
my mother say it is B. she is good at math
Answer: A
Step-by-step explanation:
Answer A is a lie. The most obvious reason being the other two statements can be proven because the y intercept of the exponential IS (0, 1). Secondly, the point (-2, 4) CAN be found on the graph. Option A is the lie because if you look, for x = 10, y = 0. Therefore, the statement that for very large values of x the exponential has very large values of y, is a lie.

what does 45=-3x tell me
Answer: x = -15
Hope this helps :)
Answer:
x = -15
Step-by-step explanation:
[One step multiplication problem]
When solving a one-step multiplication problem the easiest thing to do would be to divide the 'answer' (in this case, 45) by the coefficient (in this case, -3). A negative number times a negative number is a positive number, so x would be a negative number. 45 divided by -3 is -15.
So, x = 15.

Simplify the following fractions to their lowest possible form using the Greatest Common Factor
Answer:
13) 3/6 = 1/2
14) 4/8 = 1/2
15) 6/30 = 1/5
Step-by-step explanation:
GCF OF 3/6 = 3, SO 3/6 = 1/2
GCF OF 4/8 = 4, SO 4/8 = 1/2
GCF OF 6, 30 = 6, SO 6/30 = 1/5
Hope that helps! :)

What is the surface area of the cylinder shown below? Use 3.14 for π. A. 660 cm2 B. 863 cm2 C. 353.25 cm2 D. 785 cm2
Answer:
602.88cm²
Step-by-step explanation:
Find the image of the cylinder attached
Surface area of a cylinder = A=2πrh+2πr²
r is the radius = 4cm
Height h = 20cm
Substitute
A = 2πr(r+h)
A = 2π(4)(4+20)
A = 8π(24)
A = 192π
A = 192(3.14)
A = 602.88cm²
Hence the surface area of the cylinder is 602.88cm²

Please answer asap with explanation
Answer:
x^2 = 44y
It's really hard to explain
but if the directrix is y then your problem will have X^2= if it was x then the problem would have y^2=
then you have to have the y on the other side of the equation
and you want to multiply the 11 by 4. always multiply by 4.
