Answer:24cm
Step-by-step explanation:
if there is 2 sides with the same like the length is 8 and 2 sides(8*2)=16
and the width is half (8/2) =4 double for 2 sides (4*2) = 8
8+16
Answer:

Step-by-step explanation:
<em>Step 1: Define significance level</em>
In this hypothesis testing problem, significance levels α is selected:
, the associated z-value from Laplace table:
Φ(
) = α - 
=>
= 
<em>Step 2: Define null hypothesis (</em>
<em>) and alternative hypothesis (</em>
<em>)</em>
: rate of flu infection
= 8.3% or 8.3/100 = 0.083
: rate of flu infection
< 8.3% or 8.3/100 = 0.083
<em>Step 3: Apply the formula to check test statistic:</em>

with
is actual sampling percent,
is rate of flu infection of
,
is number of samples.
The null hypothesis will be rejected if 
<em>Step 4: Calculate the value of K and compare with </em>
We have 
=>This is good evidence to reject null hypothesis.
=> The actual rate is lower. (As
states)

Answer:
£132
Step-by-step explanation:
15% of 520 is 78

Mathematical Answer: 2cups*3/4 = 1 and 1/2 cups or 1.5 cups.
How to do it while cooking:
- Get out a container large enough to hold at least 4 cups sauce
- Get out a "1 cup" and "1/2 cup" measuring cup.
- Measure out 1 cup of sauce with the "1 cup" measuring cup.
- Measure out 1/2 of a cup of sauce with the '1/2 cup' measuring cup.
- pour both cups into the larger container.
And there you go you have 3/4 of 2 cups of sauce.

Answer:
The answer is 50 degrees
Step-by-step explanation:
The small box at the corner of the triangle indicates that the triangle is exactly 90 degrees, or a right angle. In order to solve the expression, you would need to do 40 + x = 90, which would be x = 50
