Answer:
0.108
Step-by-step explanation:
Using the poisson probability process :
Where :
P(x =x) = (e^-λ * λ^x) ÷ x!
Given that :
Each batch of bread = 3 loaves
Each loaf = 15 slices
Total slice per batch = 15 * 3 = 45 slices
Number of raising added = 100
Average number of raisin per slice, λ = 100/45 = 20/9
Hence,
Probability that a randomly chosen slice has no raising :
P(x = 0) = (e^-λ * λ^x) ÷ x!
P(x = 0) = (e^-(100/45) * (100/45)^0) ÷ 0!
P(x = 0) = (0.1083680 * 1) / 1
P(x = 0) = 0.108
An equation is modeled. What value of x makes the equation true? Explain.
A) x = 7
B) x = -1
C) x = 1
D) x = -5
Answer:
B: x=-1
Step-by-step explanation:
5x+6=1
5x+6-6=1-6
simplify
divide by 5 on both sides
x=-1
A jar contains 13 red, 27 blue, and 20 green marbles. if one marble is drawn from the jar at random, find the probability that the marble is: red, blue, not blue, green, green or red
Answer:
The probability that a marble drawn from the jar at random is red is 21.66%, that it is blue is 45%, that it is not blue is 55%, that it is green is 33.33%, and that it is green or red is 55%.
Step-by-step explanation:
Since a jar contains 13 red, 27 blue, and 20 green marbles, to determine, if one marble is drawn from the jar at random, the probability that the marble is red, blue, not blue, green, and green or red, you must perform the following calculations:
13 + 27 + 20 = 60
Red = 13/60 = 0.2166
Blue = 27/60 = 0.45
Not blue = 33/60 = 0.55
Green = 20/60 = 0.333
Green or red = 33/60 = 0.55
Therefore, the probability that a marble drawn from the jar at random is red is 21.66%, that it is blue is 45%, that it is not blue is 55%, that it is green is 33.33%, and that it is green or red is 55%.

What is the surface area of the jewelry box? And an explanation too, but if not, it’s alright!
Answer:
400
Step-by-step explanation:
The surface area is found when adding the areas of all the squares in the prism. 5x10=50, and we have that square twice, so 100. Again, 5x10=50, and we have that twice, so another 100. Then, 10x10, which is 100, and we have two of those, so 200. 100+100+200=400
Hope that helped, have a nice day!
Answer:
A. 400cm²
Step-by-step explanation:
The jewelry box is a rectangular prism.
Formula for surface area of a rectangular prism:
A = 2(w*l+h*l+h*w)
Plug in the numbers:
A = 2(10*10+5*10+5*10)
A = 400
Jeff mowed 4 yards for $45.00. at this rate how much would jeff make after mowing 11 yards?
Answer:
11 yards = $ 123.75
Step-by-step explanation:
4 yards = $ 45.00
1 yard = 45/4 = $ 11.25
11 yards= $11.25 × 11 yards
= $ 123.75

Answer:
Ordinal Scale
Step-by-step explanation:
The Ordinal Scale may be described as a type of measurement scale which is mostly used to convey qualitative differences while depicting level of magnitude and rank between the labels. The order of a ordinal Scale matters even though the difference between each cannot be measured. It is mostly employed to convey ideas such as level satisfaction, happiness, performance, grade and so on. For the categoroea given above :
Excellent represents the peak ; then Good, followed by Average, then, Below Average, and lastly Poor.

Answer: 348in^2
Step-by-step explanation:
8 x 9 = 72
72 x 2 = 144in^2 (front and back)
8 x 6 = 48
48 x 2 = 96in^2 (sides)
9 x 6 = 54
54 x 2 = 108in^2 (top and bottom)
Total Surface area = 144 + 96 + 108 = 348in^2 (second option on picture)
Answer:
Step-by-step explanation:
A journal article reports that a sample of size was used as a basis for calculating a CI for the true average natural frequency (Hz) of delaminated beams of a certain type. The resulting interval was . You decide that a confidence level of is more appropriate than the level used. What are the limits of the interval
Answer:
The limit of the (228.533, 234.735)
Step-by-step explanation:
The values are missing in the given question. Therefore, in order to attempt this question, we will make assumptions.
So, let's assume that:
sample size of the journal article that was reported = 5
which is applied for determining a 95% CI
Also, assuming that the resulting interval = (229.764, 233.504)
However, if we are to use a 99% CI which we deemed to be more appropriate;
Then, our objective is to find the limits of this particular interval in question.
To do that:
We need to first find the sample mean at 95% CI by using the formula:
[tex]\Big ( \bar {x} - t_{\alpha/2, df} \ \dfrac{s}{\sqrt{n}}}, \bar x + t_{\alpha/2, df} \ \dfrac{s}{\sqrt{n}}} \Big) = (229.764,233.504)[/tex]
Since; df = n - 1
df = 5 - 1
df = 4
Then;
[tex]\Big ( \bar {x} - t_{\alpha/2, 4} \ \dfrac{s}{\sqrt{n}}}, \bar x + t_{\alpha/2, 4} \ \dfrac{s}{\sqrt{n}}} \Big) = (233.504+229.764)[/tex]
[tex]2 \bar {x} = (463.268)[/tex]
[tex]\bar {x} =\dfrac{463.268}{2 }[/tex]
[tex]\bar {x} =231.634[/tex]
Sample mean = 231.634
Using the same formula to determine the standard deviation, we have:
[tex]\Big ( \bar {x} - t_{\alpha/2, df} \ \dfrac{s}{\sqrt{n}}}, \bar x + t_{\alpha/2, df} \ \dfrac{s}{\sqrt{n}}} \Big) = (229.764,233.504)[/tex]
[tex]\Big ( \bar {x} - t_{\alpha/2, 4} \ \dfrac{s}{\sqrt{n}}}, \bar x + t_{\alpha/2, 4} \ \dfrac{s}{\sqrt{n}}} \Big) = (233.504-229.764)[/tex]
[tex]\Big ( (\bar x + t_{\alpha/2, 4} \ \dfrac{s}{\sqrt{n}}} )- (\bar {x} - t_{\alpha/2, 4} \ \dfrac{s}{\sqrt{n}}}) \Big) = (233.504-229.764)[/tex]
[tex]\Big ( (\bar x + t_{0.05/2, 4} \ \dfrac{s}{\sqrt{4}}} )- (\bar {x} - t_{0.05/2, 4} \ \dfrac{s}{\sqrt{5}}}) \Big) = (233.504-229.764)[/tex]
At t = 0.025 and df = 4; = 2.776
[tex]2\times 2.776 \dfrac{s}{\sqrt{5}}= 3.74[/tex]
[tex]5.552 \dfrac{s}{\sqrt{5}}= 3.74[/tex]
[tex]\dfrac{s}{\sqrt{5}}= \dfrac{ 3.74}{5.552}[/tex]
[tex]\dfrac{s}{\sqrt{5}}= 0.6736[/tex]
[tex]s = 0.6736 \times \sqrt{5}[/tex]
s = 1.5063
The 99% CI is:
[tex]\implies \Big(\bar x \pm t_{\alpha/2,4} \dfrac{s}{\sqrt{n}} \Big)[/tex]
At t =0.005 and df =4; = 4.604
[tex]\implies \Big(231.634 \pm 4.604 \dfrac{1.5063}{\sqrt{5}} \Big)[/tex]
[tex]\implies \Big(231.634 \pm 4.604 (0.67364) \Big)[/tex]
[tex]\implies \Big(231.634 \pm 3.1014 \Big)[/tex]
[tex]\implies \Big((231.634 - 3.1014), (231.634 + 3.1014) \Big)[/tex]
[tex]\implies \Big( 228.533, 234.735 \Big)[/tex]
Enter the trigonometric equation you would use to solve for x. Do not solve the equation.
Answer:
[tex]x=12\times \text{tan}(20^0)[/tex]
Step-by-step explanation:
From the figure attached,
Measure of an angle = 20°
Measure of the opposite side = x
Measure of the adjacent side = 12
By applying tangent rule in the given right triangle,
tan(20°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
[tex]\text{tan}(20^0)=\frac{x}{12}[/tex]
[tex]x=12\times \text{tan}(20^0)[/tex]
Therefore, equation to get the value of 'x' will be,
[tex]x=12\times \text{tan}(20^0)[/tex]

Answer:
Value of ∠1 = 102°
Value of ∠1 = 72°
Step-by-step explanation:
Given:
∠ S = 42°
∠ A = 30°
Find:
Value of ∠1
Value of ∠2
Computation:
Using angle sum property;
Sum of all interior angle of a triangle = 180°
∠ S + ∠ A + ∠ 1 = 180
42 + 30 + ∠ 1 = 180
72 + ∠ 1 = 180
∠ 1 = 180 - 72
∠ 1 = 102
Value of ∠1 = 102°
∠ 1 and ∠ 2 makes a straight line
So,
∠ 1 + ∠ 2 = 180
102 + ∠ 2 = 180
∠ 2 = 180 - 102
∠ 2 = 72
Value of ∠1 = 72°
