2. 5 · 4² + (2 · 3 + 2) = 5 · 16 + 6 + 2 = 88
3. (4 + 3)² - 12 + 3 = 49 - 12 + 3 = 40
4. 64 ÷ 4 · 3 = 16 · 3 = 48

yards wide?
Don’t tell me to “download the answer” that’s bs
Answers
Answer:
Raul needs 42 yards of fence.
Step-by-step explanation:
Perimeter of a rectangle:
The perimeter of a rectangle of length l and width w is given by:
P = 2(l + w)
In this question:
The fence is rectangular.
12 yards long means that l = 12.
9 yards wide means that w = 9.
Perimeter:
P = 2(12 + 9) = 2(21) = 42
Raul needs 42 yards of fence.

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.
Answers
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))

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

18 of the 47 people surveyed said they were not interested in trying a sample of a new soft drink. Find probability that a randomly selected person was interested in trying a new drink.
Answers
Answer: 0.62
Step-by-step explanation:
Total people= 47
Let A be the event of selecting person was interested in trying the new drink.
Person not interested in trying a sample of a new soft drink (nA')=18
Person interested in trying a sample of a new soft drink (nA)=47-18=29
Thus probability that a randomly selected person was interested in trying the new drink
P (A) = 29/41 = 0.6170 (or) 0.62
Thus, probability that a randomly selected person was interested in trying the new drink is 0.62.
47-18=29 people interested in the new drink
29/47=0.617
0.617*100=61.7% chance

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
Answers
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)

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.
