Step-by-step explanation:
In Exercises 1-4, the sample size n, probability of success p, and probability of
failure q are given for a binomial experiment. Determine whether you can use a
normal distribution to approximate the distribution of x.
1. n = 24, p = 0.85, 9 = 0.15
2. n = 15, p = 0.70, q = 0.30
3. n = 18, p = 0.90, q = 0.10
4. n = 20, p = 0.65, q = 0.35
Answers
Answer:
1. No
2. No
3. No
4. Yes
Step-by-step explanation:
Binomial approximation to normal.
The binomial probability distribution has parameters n, p and q.
If
[tex]np \geq 5[/tex] and [tex]nq \geq 5[/tex], you can use the normal approximation.
1. n = 24, p = 0.85, q = 0.15
[tex]np = 24*0.85 = 20.4 > 5[/tex]
[tex]nq = 24*0.15 = 3.6 < 5[/tex]
So no.
2. n = 15, p = 0.70, q = 0.30
[tex]np = 15*0.7 = 10.5 > 5[/tex]
[tex]nq = 15*0.3 = 4.5 < 5[/tex]
So no.
3. n = 18, p = 0.90, q = 0.10
[tex]np = 18*0.9 = 16.2 > 5[/tex]
[tex]nq = 18*0.1 = 1.8 < 5[/tex]
No
4. n = 20, p = 0.65, q = 0.35
[tex]np = 20*0.65 = 13 > 5[/tex]
[tex]nq = 20*0.35 = 7 > 5[/tex]

The Volume of dirt required for the Margo's garden which is made of 2 rectangular prisms is, 107 cubic feet, So option D is correct
What is Volume?In mathematics, Space occupied by three dimensional objects is called Volume. Basically it is a space within closed region of every three dimensional objects.
In given problem, we have two rectangular prisms
One has sides (1 feet, 3 feet, 3 feet)
Another one has sides (2 feet, 7 feet, 7 feet)
Volume of a rectangular prism = Length×Height×Width
Volume of a rectangular prism 1 = 3×1×3 = 9
Volume of a rectangular prism 2 = 7×2×7 = 98
Total Volume = 107
Hence, Total dirt required 107 cubic feet

Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.
Answers
Answer:
I = $ 6.00
Step-by-step explanation:
Equation:
I = Prt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 10%/100 = 0.1 per year,
then, solving our equation
I = 60 × 0.1 × 1 = 6
I = $ 6.00
The simple interest accumulated
on a principal of $ 60.00
at a rate of 10% per year
for 1 years is $ 6.00.

O B. X+ 3 with a remainder of -2
O C. 2x-3 with a remainder of 5
O D. 2x-6 with no remainder
Answers
Answer:
2x² - 2x - 12 ÷ (x+2)
= 2x - 6
D. 2x-6 with no remainder
The quotient when (x + 2) is divided into the polynomial 2x² - 2x - 12 is, (2x - 6) with no remainder.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
We have to given that;
To find the quotient when (x + 2) is divided into the polynomial
2x² - 2x - 12.
Now,
The polynomial is,
⇒ 2x² - 2x - 12
⇒ 2 (x² - x - 6)
⇒ 2 (x² - 3x + 2x - 6)
⇒ 2 [ x (x - 3) + 2(x - 3) ]
⇒ 2 [ (x + 2) (x - 3) ]
Hence, We can divide polynomial by (x + 2) as;
⇒ 2 [ (x + 2) (x - 3) ] ÷ (x + 2)
⇒ 2 (x - 3)
⇒ 2x - 6
Therefore, the quotient when (x + 2) is divided into the polynomial
2x² - 2x - 12 is, (2x - 6) with no remainder.

Answers
Answer:
c. We are 92% confident that the mean height of the entire business is in this interval.
f. The 85% confidence interval is a subset of the 92% confidence interval.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
Margin of error:
The larger the confidence interval, the larger the margin of error. That means that for example, an 85% confidence interval is a subset of the 92% confidence interval.
In this question:
92% confidence interval -> We are 92% sure that the population mean is in this interval.
The 85% confidence interval is a subset of the 92% confidence interval.
So options c and f.

Now, we have a right triangle with a known angle and a known side. With this type of triangle, we can use basic trigonometry applications.
The side opposite to the 90 degree angle is the hypotenuse. The hypotenuse is YZ. The two legs are WZ and YW.
We can use cosine function to find tangent because the YZ is not known.
tangent is side opposite of angle divided by side adjacent to angle.
tan(72) = WZ / 4.25
4.25tan(72) = WZ
0.3 = WZ
