Answer: (1.5, 1.0)
Step-by-step explanation:
On coordinate plane , if we plot a point , we start from origin that is (0,0).
Direction for Empire State Building : 1.50 units to the right and 1 unit up to the origin .
By considering origin as the initial point, frim we move 1.45 units to the right on x-axis( positive) showed by red
Then move 1 unit up parallel to positive y axis showed by green.
So, the ordered pairs show the location of the Empire State Building = (1.5, 1.0) [as both axis are positive in this region.]
So correct option = (1.5, 1.0)
Answer:
y = 5
Step-by-step explanation:
<u>Step 1:</u>
(18) -7y = -17
-18 -18
<u>Step 2:</u>
-7y = -35
÷-7 ÷-7
y = 5
Answer:hello
Step-by-step explanation:
Answer:
a: z = -1.936
b: 0.0265
d: z < -1.645
Reject H0 if z < -1.645
Step-by-step explanation:
We are given:
H0: µ = 20
HA: µ < 20
n = 60, sample mean: 19.6, σ = 1.6
Since the alternate hypothesis has a < sign in it, it is a left tailed test. The < or > sign in the alternate hypothesis points towards the rejection region.
For a: We need to calculate the test statistic for our situation. This is done with a z-score formula for samples.
For b: we need to use the z-score table to look up the p-value for the score we calculate in part a. The p-value is 0.0265. This means that there is only about a 2.65% chance that the sample values were a result of random chance.
For d: Since the significance level is 0.05, and this is a one tailed test, we have a critical value of z < - 1.645. This means that if the z-score we calculate in part a is less than -1.645, we will reject the null hypothesis
