C 15 seconds
D 17 seconds
Answers
Answer:
C. 15 seconds
Step-by-step explanation:
It wouldn't be A, because 10 seconds can download 348 kilobytes, it wouldn't be B too as it would be at about 400+ kilobytes, the only possible answer is 15 seconds as the last option takes 17 seconds for 715 kilobytes.
The area of a rectangle is 20 mm2. If the width is 4 mm, find the length?

Carmen and Matt are conducting different chemistry experiments in school. In both experiments, each student starts with an initial amount of water in a flask. They combine two chemicals which react to produce more water. Carmen's experiment starts with 30 milliliters of water in a flask, and the water increases in volume by 8.5 milliliters per second. Matt's experiment starts with 10 milliliters of water and increases in volume by 28% each second.
Which two conclusions can be made if f represents the volume of water in Carmen's flask and g represents the volume of water in Matt's flask?
The volume of water in Carmen's flask is increasing at a faster rate than the volume of water in Matt's flask over the interval [6, 8].
The volume of water in Carmen's flask is increasing at a slower rate than the volume of water in Matt's flask over the interval [4, 6].
The volume of water in Carmen's flask will always be greater than the volume of water in Matt's flask.
The volume of water in Matt's flask will eventually be greater than the volume of water in Carmen's flask.
The volume of water in Carmen's flask is increasing at a slower rate than the volume of water in Matt's flask over the interval [0, 2].

The amount of red candies is unknown , let it be represented by y
To find the amount of red candy :
y= (32% of 400)
y = 32/100 × 400
y = 32×400/100
y= 32×4
y = 128
Therefore 128 candies are red

Answer:
222 cm²
Step-by-step explanation:
The surface area can be found using the formula ...
A = 2(LW +H(L+W))
To minimize fraction nonsense, we'll let H be the fraction.
A = 2(12·8 +(3/4)(12 +8)) = 2(96 +15) = 222
The surface area of the prism is 222 square centimeters.
Simon wants to earn as many points as possible in one turn in a game. Two number cubes whose sides are numbered 1 through 6 are rolled. He is given two options for the manner in which points are awarded in the turn.
OPTION A: If the sum of the rolls is a prime number, Simon receives 15 points.
OPTION B: If the sum of the rolls is a multiple of 3, Simon receives 12 points.
Which statement best explains the option he should choose?
A. Simon should choose Option B. The mathematical expectation of this option is 6.25 and is the greater mathematical expectation of the two options.
B. Simon should choose Option A. The mathematical expectation of this option is 6.25 and is the greater mathematical expectation of the two options.
C. Simon should choose Option B. The mathematical expectation of this option is 4 and is the greater mathematical expectation of the two options.
D. Simon should choose Option A. The mathematical expectation of this option is 4 and is the greater mathematical expectation of the two options.
Answers
Answer: b. Simon should chose option a. The mathematical expectation of this option is 6.25 and is the greater mathematical expectation of the two options.
Statement B. Simon should choose Option A. The mathematical expectation of this option is 6.25 and is the greater mathematical expectation of the two options is correct.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
The probability that the sum of the rolls is a prime number:
P(sum is prime) = 15/36 =0.416
Expected number of points = 0.416×15 =6.25
Probability that f the sum of the rolls is a multiple of 3,
P(sum of rolls is multiple of 3) = 12/36 = 0.33
Expected number of points = 0.33×12 = 3.96
Thus, statement B. Simon should choose Option A. The mathematical expectation of this option is 6.25 and is the greater mathematical expectation of the two options is correct.

When three squares are joined at their vertices to form a right triangle, the combined area of the two smaller squares is the same as the area of the largest square. Which three squares will support this statement?
Answers
Answer:
J
Step-by-step explanation:
Area of a square = L x W
F:
(5 x 5) + (4 x 4) = 81
25 + 16 = 81
41 = 81 INCORRECT =( X
H:
64 + (5 x 5) = (13 x 13)
64 + 25 = 169
89 = 169 INCORRECT =( X
G:
(6 x 6) + (5 x 5) = (7 x 7)
36 + 25 = 49
61 = 49 INCORRECT =( X
J:
144 + (5 x 5) = 169
144 + 25 = 169
169 = 169 CORRECT =)
Two numbers have a sum of - 6 and a product of 9.
Use the quadratic equation n^2 - 6n + 9 = 0 to determine the two numbers.
n2 - 6n + 9 = 0
Answers
Answer:
3, 3
Step-by-step explanation:
[tex]n^2 - 6n + 9 = 0 \\ n^2 - 3n - 3n+ 9 = 0 \\ n(n - 3) - 3(n - 3) = 0 \\ (n - 3)(n - 3) = 0 \\ n - 3 = 0, \: \: n - 3 = 0 \\ n = 3, \: \: n = 3[/tex]
