Answer:
9% probability that Jim will be accepted at both universities
Step-by-step explanation:
We have these following probabilities:
A 20% probability that Jim is accepted into the University X.
A 45% probability that Jim is accepted into the University Y.
What is the probability that Jim will be accepted at both universities?
It is the multiplication of both these probabilities
So there is a 0*2*0.45 = 0.09 = 9% probability that Jim will be accepted at both universities
Answer:
H0 : mu1 = mu2
Ha : mu1 ≠ mu2
Which means
Null hypothesis H0; the true mean price when buying from a friend mu1 and the true mean price when buying from a stranger mu2 is the same/equal
Alternative hypothesis Ha; the true mean price when buying from a friend mu1 and the true mean price when buying from a stranger mu2 is different (not equal)
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean(i.e it tries to prove that the old theory is true). While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
Therefore, for the case above;
H0 : mu1 = mu2
Ha : mu1 ≠ mu2
Which means
Null hypothesis H0; the true mean price when buying from a friend mu1 and the true mean price when buying from a stranger mu2 is the same/equal
Alternative hypothesis Ha; the true mean price when buying from a friend mu1 and the true mean price when buying from a stranger mu2 is different (not equal)
> 16.35 times 10 = 16.35 x 10 = 163.5
> 163.5 to the power of 2 = 163.5 x 163.5 = 26732.25
* (16.35 x 10)^2 = 26732.25
Hello!
Point-slope form is this: 
. In this form, m is the slope, 
and 
is an ordered pair, or point.
To find the slope, we need to use the slope formula. The slope formula is: 
. We can assign the point (-9, 6) to and and (-7, -8) to 
and 
.
Now, we can substitute the ordered pairs into the formula and solve.
Since the slope is equal to -7, we can substitute the slope and a point into the point-slope form.
Therefore, your point-slope formula is y - 6 + -7(x + 9) or y + 8 = -7(x + 7).
