Answer:
since p-value (0.0801) is < 0.10, the result is significant
so, we reject Null hypothesis
Step-by-step explanation:
Given the data in the question;
Null Hypothesis H₀ : p = 0.27
Alternative Hypothesis H₁ : p ≠ 0.27
Test statistic
z = ( - p)/√()
we substitute
z = (0.25 - 0.27)/√()
z = -0.02 / √( 0.1971/1500)
z = -0.02 / 0.01146
z = -1.7452 ≈ -1.75
p-value;
for z = -1.75, the two tailed p value is 0.0801
Decision
since p-value (0.0801) is < 0.10, the result is significant
so, we reject Null hypothesis

Explanation:</h2>
A parallelogram is a quadrilateral that has two pair of opposite sides and each pair measure the same. In order to illustrate this problem, see the figure below. Here we know some facts:
- Side AB measures x cm
- Side DC measures 4 cm
By definition, opposite sides in any parallelogram measure the same, so AB and DC are opposite, therefore:

Answer:
2
Step-by-step explanation:
let the number be n, then
n = 4n - 6 ( subtract 4n from both sides )
- 3n = - 6 ( divide both sides by - 3 )
n = 2
That is the number is 2
Answer:
x = 2root(22)
see image.
Step-by-step explanation:
The triangle shown is one big triangle cut into two more smaller triangles: one medium-sized and one smaller.
ALL THREE TRIANGLES ARE SIMILAR BY AA.
Set the two smaller triangles up so you can see the corresponding sides. x is the short leg in one triangle and it is the long leg in the smallest triangle. Set up a proportion.
22/x = x/4
crossmultiply
x^2 = 22•4
x^2 = 88
square root both sides.
x = sqroot(88)
x = 2sqroot(22)
see image.
