Answer:
Isosceles triangle
Step-by-step explanation:
If the measure of two sides or two angles of a triangle are equal, then it is isosceles triangle.
Answer:
Test statistic |Z| = 0.1040 < 1.96 at 0.05 level of significance
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that a report on the nightly news broadcast stated that 10 out of 108 households with pet dogs were burglarized
First proportion
Given that a report on the nightly news broadcast stated that 20 out of 208 households without pet dogs were burglarized
Second proportion
where
P = 0.09486
Q = 1 - P = 1 - 0.09486 = 0.90514
<u><em>Step(ii):-</em></u>
Test statistic
Z = -0.1040
|Z| = |-0.1040|
|Z| = 0.1040
Critical value Z = 1.96 at 0.05 level of significance
<h3>
Answer: 1/2</h3>
Explanation:
Here's the event space
E = {1,2,3}
this represents all of the desired events we want, which is rolling less than a 4 on a standard number cube (aka a die). There are A = 3 items in this set.
The sample space is the set of all possible outcomes, namely,
S = {1,2,3,4,5,6}
which is all of the values on the die. There are B = 6 items in this set.
Divide the values of A and B to get the theoretical probability:
P(rolling a number less than 4) = A/B = 3/6 = 1/2
6x-6=7x-8
-6=x-8
2=x
Now that we know the value of x we plug in the value to solve CT .
CT =12
The answer is $32
how?: divide .75 from 24, getting 32. to check if it’s correct, multiply.25 and 32 which should get you 8, subtract 8 from 32 and you should get 24 as the end product
