Answer:
width= 5 inches
length= 13 inches
Step-by-step explanation:
width= W
length= w+8
perimeter= 2(lengths)+ 2(width)
(subsistute is known values)
multiply
36=2(w+8) 2(W)
add
36=4W
Divide both sides by 4
W=5
Length=5+8 inches= 13

23. The mean weight of trucks traveling on a particular section of 1-475 is not known. A state highway inspector needs an estimate of the mean. He selects a random sample of 49 trucks passing the weighing station and finds the mean is 15.8 tons, with a standard deviation of the sample of 4.2 tons. What is probability that a truck will weigh less than 14.3 tons
Answer:
0.3594 = 35.94% probability that a truck will weigh less than 14.3 tons
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean is 15.8 tons, with a standard deviation of the sample of 4.2 tons.
This means that [tex]\mu = 15.8, \sigma = 4.2[/tex]
What is probability that a truck will weigh less than 14.3 tons?
This is the pvalue of Z when X = 14.3. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{14.3 - 15.8}{4.2}[/tex]
[tex]Z = -0.36[/tex]
[tex]Z = -0.36[/tex] has a pvalue of 0.3594
0.3594 = 35.94% probability that a truck will weigh less than 14.3 tons

What would be the volume of this solid if the height were halved and the other dimensions were reduced proportionally? Round to the nearest whole number.
A. 13 cm3
B. 26 cm3
C. 15 cm3
D. 21 cm3
no dam links
Answer:
The height for the original part is 10 cm
Never mind that the solid is standing at the angle of 60 degrees.
If you cut the bottom of the solid at the angle of 30 degrees, and put that part on the top of the solid,
the height is going to be exactly 10 cm.
So, we have... V = (10 * 4 * 3) / 8
or V = 5 * 2 * 1.5

9514 1404 393
Answer:
50.3 square units
Step-by-step explanation:
The circle has a diameter of 8 units, so a radius of 4 units. The area formula is ...
A = πr²
A ≈ 3.14159(4²) ≈ 50.265
The area of the circle is about 50.3 square units.
A random sample of 25 items is drawn from a population. The sample mean is 850 and population standard deviation is 15. Find a 90% confidence interval
Answer:
The 90% confidence interval of the mean
(846.154, 853.846)
Step-by-step explanation:
Step(i):-
Given that the sample size 'n' = 25
Given that the sample mean (x⁻) = 850
The standard deviation of the Population (σ) = 15
Level of significance = 0.10
Step(ii):-
The 90% confidence interval is determined by
[tex](x^{-} - Z_{0.05} \frac{S.D}{\sqrt{n} } , x^{-} + Z_{0.05} \frac{S.D}{\sqrt{n} } )[/tex]
[tex](850 - 1.282\frac{15}{\sqrt{25} } , 850+ 1.282 \frac{15}{\sqrt{25} })[/tex]
(850 - 3.846 , 850 + 3.846)
(846.154 , 853.846)
Final answer:-
The 90% confidence interval of the mean
(846.154, 853.846)

Answer:
x = 20
y = 20
Step-by-step explanation:
Remark
This is a proportional question. One triangle is inside the other. I've used the larger to the smaller.
Equation
x/16 = 15 / 12
Solution for x
12x = 15 * 16
Divide by 12
x = 15 * (16/12)
x = 15 * (4/3)
x = 60 / 3
x = 20
==========================
Solution for y
(y + 5) / y = 15/12 Reduce the right
(y + 5) / y = 5/4 Cross Multiply
4(y+5) = 5y Remove the brackets
4y + 20 = 5y Subtract 4y from both sides
20 = 5y - 4y
20 = y

An alternative strategy for the expo function uses the following recursive definition: expo(number, exponent) = 1, when exponent = 0 = number * expo(number, exponent – 1), when exponent is odd = (expo(number, exponent // 2)) ** 2, when exponent is even Define a recursive function expo that uses this strategy, and state its computational complexity using big O notation.
Answer:
The recursive function in Python is as follows
def expo(nmber, exponent):
power = exponent
if power == 0:
return 1
if power %2 == 1:
power = power - 1
return nmber * expo(nmber, power)
else:
power = power/2
return expo(nmber, power) ** 2
The time complexity is O(log(n))
Step-by-step explanation:
See attachment for complete program where comments are used for explanation.
The Time Complexity
The function is then called power - 1 times for odd exponents or power/2 times for even exponents before it reaches the base case.
As the exponent is divided by 2, for even exponents; it means that the function tends to log(n). log(n), in this case represents the base case.
Since the function is repeated, then the time complexity is: O(log(n))

No
For a quadrilateral to be cyclic (possible to inscribe in a circle), the opposite angles must be supplementary (add/sum up to 180°).
Step-by-step explanation:
With the given quadrilateral, there are two opposite angles, labeled as 68° and 122°.
68° and 122° are not supplementary because they are greater than 180°.
68° + 122° = 190°.
190° > 180°.
Because they are not supplementary, the quadrilateral cannot be inscribed.
Therefore, a quadrilateral is cyclic if and only if it's opposite angles are supplementary.
Answer:
yes
Step-by-step explanation:
if it is large enough
