The reason why the far eastern diplomat was at the north pole was : he got disoriented To travel in the past, people in the past rely on stars and compass. But due to electromagnetic phenomenon, the compass tend to not functioning properly and make it really difficult to actually find out the correct path
Answer:
.
Step-by-step explanation:
In quadrilateral QRST, Q(-1,0), R(5,0), S(3.5,-6), T(-2.5,-6).
In quadrilateral Q'R'S'T', Q'(-1,2), R'(1,2), S'(0.5,0), T'(-1.5,0).
Distance formula:
Using distance formula , we get
Now,
Therefore the scale factor is .
Answer:
It would be A, or the first graph
Step-by-step explanation:
So we’ve now created an equation
2x + 3y ≤ 6
From here, we can convert this into something easier to read
y ≤ -2/3x + 2
Now, we know that the y-intercept is 2 so either A or B
We also know the shaded area should be below the line (because the smallest part of the “≤” is facing the y).
Therefore, the answer is A
Recall that
which means
Now, 
could be positive or negative, which means 
. If we specifically knew the sign of was positive, then we can simplify and write
or if it's negative,
Answer:
Step-by-step explanation:
Hello!
You have a sample of 200 people, they were asked their primary source of news, categorized in (1) Television, (2) Radio, (3) Internet and (4) Other.
And your objective is to test if the proportions in this sample follow the known frequencies 10%, 30%, 50%, and 10%.
The propper statistic test to use to probe if the sample follows the known or historical distribution is Chi-Square goodness of fit test. In this test, what you state in the null hypothesis is the model or distribution you want to test. In this case, you've to write down the proportions for each category:
H₀: P(1)= 0.10; P(2)= 0.30; P(3)= 0.50; P(4)= 0.10
I hope you have a SUPER day!
