8.1 I think but there's an app called, tiger something and it tells,you the answers
Answer:
40
Step-by-step explanation:
In the triangle, there is a 90 degree angle and Angle 1 (what we are looking for) and the other angle, lets call is Angle 2.
Lets find Angle 2 first.
First of all, the angle between angle 40 and 90 can be found easily.
That angle (lets call it "x) and 40 and 90 make a straight angle (180 degrees). So we can write:
40 + x + 90 = 180
Lets solve for "x":
40 + x + 90 = 180
130 + x = 180
x = 180 - 130
x = 50
Now, This angle (50) and Angle 2 are same [vertical angles]
So,
Angle 2 = 50
Now, there are 180 degrees in 3 angles in a triangle. So for the triangle shown, we cacn write:
90 + Angle 1 + Angle 2 = 180
90 + Angle 1 + 50 = 180
Angle 1 + 140 = 180
Angle 1 = 180 - 140
<u>Angle 1 = 40</u>
Try this options:
a. total - 6 digits, '6' - 1 digit, then probability of rolling a '6' is 1/6;
b. total - 6 digits, '6' - 1 digit, then probability of rolling 1,2,3,4,5 is 5/6;
c. if probability of rolling a '6' is p and not rolling a '6' is q, then p+q=1;
d. if expected probability of one rolling a '6' is 1/6, then numbers of times of rolling a '6' during 120 times is 120/6=20 times.
D. Circumfrence to diameter is the answer
Answer:
Yes. more than 50% is true.
Step-by-step explanation:
Given that a poll is taken that shows that 795 out of 1500 randomly selected, independent people believe the rich should pay more taxes than they do.
Sample proportion p =
Sample size n = 1500
Hypotheses would be
(Right tailed test at 5% significance level)
Std error of proportion =
Proportion difference = p-P =
Test statistic= p diff/std error =
p value <0.05
Hence reject null hypothesis
There is significant difference in the two proportions and hence a majority (more than 50%) believe the rich should pay more taxes than they do is supported by statistical evidence.
