Answer:
4
Step-by-step explanation:
2 people chose 1/3
2 people chose 1/2
2+2=4
22.5 cm* (1 block/ 1.5 cm)= 15 blocks.
The correct answer is B. 15~
Answer:
0.05155 or 5.155%
Step-by-step explanation:
We are given;
Weight of passenger cars the ferry can accommodate = 79 tons of passenger cars
Number of cars loaded = 39
Thus;
population mean weight; μ = 1.9
Since it can accommodate 79 tons of passenger cars, then their average weight should not exceed;
79/39 = 2.03 thus;
Sample mean; x¯ = 2.03
Standard deviation; σ = 0.5
Sample size; n = 39
Let's find the z-score value;
z = (x¯ - μ)/(σ/√n)
Thus;
z = (2.03 - 1.9)/(0.5/√39)
z = 0.13/0.08
z ≈ 1.63
Thus; P(z > 1.63) = 1 - P(z < 1.63)
From the z-score table attached, the p-value which is the probability is P(z < 1.63)
Thus;
P = 1 - 0.94845
P = 0.05155 or 5.155%
Answer:
X = 5
Step-by-step explanation:
Here is what I am picturing (not to scale)
A ----------------B-----------C
We are given the information of AB (which equals 3x + 1), BC (which equals 4x - 5), and AC (which equals 8x - 9).
With reference to the line, AB + BC = AC
So,
3x + 1 + 4x - 5 = 8x - 9
7x - 4 = 8x - 9
5 = x
Answer:
(0,-4)
Step-by-step explanation:
The y-intercept is where the line intersects the y-axis. The y-intercept is written in the form (0,x), where x = y-coordinate/y-intercept. Thus, the answer is (0,-4).
