Answer:
y = - 19
Step-by-step explanation:
Express 210 and 55 as products of their prime factors, that is
210 = 2 × 3 × 5 × 7
55 = 5 × 11
Identify the prime factors that both numbers have in common and multiply them.
Here only 5 is common, thus
HCF = 5
Thus
5 = 210 × 5 + 55y, that is
5 = 1050 + 55y ( subtract 1050 from both sides )
- 1045 = 55y ( divide both sides by 55 )
y = - 19
Answer:
The mean is 27.8
The required variance is 23.9358
Step-by-step explanation:
Consider the provided information.
Here the random sample size, n = 200
Unemployment rate is 13.9% = p = 0.139
Part (a) expected number of grads who are unemployed.
Hence, the mean is 27.8
Part (b) variance of the random variable "number of grads who are unemployed.
Hence, the required variance is 23.9358
Answer:
3y = 8x + 18
for y-intercept let x = 0
3y = 8(0) + 18
3y = 18
y = 6
y-intercept is (0, 6)
THIS IS TRUE
Commutative property allows you to change the order of the terms when adding or multiplying without changing the outcome.
Answer:
<h2>Graph C.</h2>
Step-by-step explanation:
The given situation is about an increasing function, that is, a positive correlation between the independent variable and the dependent variable. This positiva correlation is shown by the graph C only, because graph A is showing a negative correlation and graphs B and D aren't showing a clear correaltion.
Therefore, the right answer must be C, that is, graph C is showing a positive correaltion. In other words, it shows "as x increases, y increases".
