Answer:
3/91 ; 36/91
Step-by-step explanation:
1) favourable event/ total possibilities * favourable event/ new total possibilities
3/14 * 2/13 = 3/91
2) it is simplier calculate the probability of the opposite event (no balls are blue)
11/14 * 10/13 = 55/91
91 - 55 = 36
final answer 36/91

Step-by-step explanation:
The volume of the cylinder is
V2 = (pi)r^2L
= (3.14)(12.5 xm)^2(50 cm)
= 24531.3 cm^3
The volume of the half cylinder is
V3 = (1/2)(24531.3 cm^3)
= 12265.7 cm^3
If V1 is the volume of the prism then the total volume of the storage chest is
V = V1 + V2 + V3
= 37500 cm^3 + 24531.3 cm^3 + 12265.7 cm^3
= 74297.0 cm^3

For two functions, m(x) and p(x), a statement is made that m(x) = p(x) at x = 7. What is definitely true about x = 7? (2 points)
a
Both m(x) and p(x) cross the x-axis at 7.
b
Both m(x) and p(x) cross the y-axis at 7.
c
Both m(x) and p(x) have the same output value at x = 7.
d
Both m(x) and p(x) have a maximum or minimum value at x = 7.
Answers

Answer:
c. Both m(x) and p(x) have the same output value at x = 7.
Step-by-step explanation:
For input value x, m(x) is the output value.
m(7) is the output value of the function m(x) when x=7.
p(7) is the output value of the function p(x) when x=7.
The statement m(x) = p(x) for x=7 is a statement that the output values are the same at x=7.

49 minutes
Step-by-step explanation:
Volume
v = πr²h
v = π(2.5²)4
v = 78.5 ft³

Step-by-step explanation:
Given 9/16×4/12+9/16×-5/9
Using the PEMDAS rule;
Multiplication first
(9/16×4/12)+(9/16×-5/9)
= 3/4 * 1/4 + -5/16
= 3/16 - 5/16
= (3-5)/16
= -2/16
= -1/8
Hence the required answer is -1/8

PLEASE HELP ME :(. Look at this system of equations.
X - 8y = -3
5x - 2y = 4
What value of a will make this system have the same solution?
ax = -19
5x - 2y = 4
Answers
9514 1404 393
Answer:
a = -19
Step-by-step explanation:
In the first set of equations, subtract 4 times the second equation from the first.
(x -8y) -4(5x -2y) = (-3) -4(4)
-19x = -19 . . . . simplify
Comparing this to the equation ...
ax = -19
we see that they will have the same solution when a = -19.
Write the equation of the line in fully simplified slope-intercept form.

Answer:
Hi your question is incomplete attached below is the complete question
answer : p ( X < 725 ) = 0.0116
Step-by-step explanation:
Given data:
Average life of bulbs (μ ) = 750 hours
standard deviation (б ) = 55 hours
n ( sample size ) = 25
X = 725
Probability that the mean life of a random sample of 25 bulbs will be less than725 hours
p ( X < 725 ) = p (( X - μ )/ б √n < 725 - 750 / 55√25 )
= P ( Z > - 2.27 )
Hence P ( X < 725 ) = 0.0116 ( using Z-table )
