Answer:
A
Step-by-step explanation:
The volume (V) of the triangular prism is calculate as
V = area of triangular face × depth
area of triangle = 0.5 × 9 × 4 = 0.5 × 36 = 18 units², thus
V = 18 × 15 = 270 units³ → A
Answer:
Null Hypothesis years
Alternative hypothesis years
Step-by-step explanation:
Hypothesis is a tentative guess. In a null hypothesis, we state that there's no statistical significance between the variables. For alternative hypothesis, it's stated that there's significant statistical relation between the provided variables. In this case, the null Hypothesis is years and the alternative hypothesis is years
We can decide to accept or reject either null hypothesis or alternative hypothesis
Answer:
option B
35
Step-by-step explanation:
Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter.
Formula to calculate combination
nCr = n! / r! * (n - r)!
We are given C(7,3)
here n = 7
r = 3
<h3>So plug values in the formula </h3>
7C3 = 7! / 3! * (7 - 3)!
= (7x6x5x4x3x2) / (3x2)(4x3x2)
= (7x6x5) / (3x2)
= 210 / 6
= 35
Answer:x=2y+6
