Answer:
c. 0.088
Step-by-step explanation:
Let p(s) be the proportion of apples defected in the sample. The probability that p(s)<0.05 can be calculated by calculating z statistic of 0.05:
where
- p is the proportion of the apples in fact defected (0.08)
- N is the sample size (150) Then,
z(0.05)=
And P(z<-1.354)≈0.0879
Therefore the probability that a random sample of 150 among 8% defected apples can be accepted is 0.088.
The length of one leg is 22 units. If you search up 45 45 90 triangle you can find the rules that go with solving for these kinds of triangles.
We can rephrase the question as "What percent of 50 is 20?".
"What percent ..." is an unknown. We'll use the variable x to represent this unknown.
The word 'of' in mathematics can mean 'multiply'. Likewise the word 'is' can mean 'equal'.
Now we have the phrase "20 equals to x times 50".
Or in an equation: 20 = x * 50
Solve for x.
20 = x * 50
= x <-- Divide both sides by 50
Simplify the fraction.
Convert the fraction into a decimal.
= 0.4
Convert the decimal into a percent.
0.4 = 40%
So, 40% is the answer.
Using an indirect proof:
Assume that the figure is a trapezoid.
All trapezoids are quadrilaterals.
All quadrilaterals' interior angles add up to 360° because any n-gon's interior angles add up to 180(n-2)°.
We are given that the trapezoid has three right angles.
All right angles are 90°, thus these right angles have a total measure of 270°.
We can conclude fourth angle must be 90°.
If it has four right angles, it is a rectangle.
Rectangles have two sets of parallel sides.
However, trapezoids have exactly one set of parallel sides.
Alas, our figure cannot be a trapezoid.
Answer:
Meningitis
Step-by-step explanation:
Meningitis is a inflammation of the membrane surrounding your brain and spinal cord.
In most cases it is caused by viral infection.
Some cases it improve without treatment in few days
Symptoms include:
