Answer: 65 degrees
Using the property of vertical angles, the measurement of angle x is going to be 65 degrees.
Single angle x is directly opposite of the 65° angle given, we can figure out what angle x will be as they will be congruent.
By using the Vertical Angle Theorem, we can say
--> x = 65
Definition of Vertical Angle Theorem: states that the opposite (vertical) angles of two intersecting lines are congruent.

A rectangular prism has a length of 20 meters, a height of 12 meters,
and a width of 12 meters. What is its volume, in cubic meters?
Answers
Answer:
2880 cubic meters.
Step-by-step explanation:
To find the area of a rectangular prism, multiply the length width and height.
20*12*12=144*20=2880
The volume of the Rectangular Prism is 2880 cubic meters.
What is Rectangular Prism?Rectangular prism can be defined as a" 3-dimensional solid shape which has six faces that are rectangles. A rectangular prism is also a cuboid".
According to the question,
Length of the rectangular prism = 20 meters
Height of the rectangular prism = 12 meters
Width of the rectangular prism = 12 meters
Formula for Rectangular Prism = length × breadth × height
= 20 × 12 × 12
= 2880 cubic meters.
Hence, the volume of the Rectangular Prism is 2880 cubic meters.

Pharmaceutical scientists tested the effectiveness of a new drug designed to cure malaria. They randomly
assigned 400 infected lab rats to receive either the new drug or an existing drug and recorded how many
rats were cured at the end of the study. Here are their results:
Cured

Total
New drug
176
24
200
Existing drug

They want to use these results to construct a 99% confidence interval to estimate the difference in the
proportion of these rats that would be cured under each drug (new - existing). Assume that all of the
conditions for inference have been met.
Which of the following is a correct 99% confidence interval based on their data?
Choose 1 answer:
8 +0.068
Answers
Using the z-distribution, as we are working with a proportion, it is found that the 99% confidence interval is (-0.049, 0.129).
What is the mean and the standard error for the distribution of differences?For each sample, we have that:
[tex]p_N = \frac{176}{200} = 0.88, s_N = \sqrt{\frac{0.88(0.12)}{200}} = 0.023[/tex]
[tex]p_E = \frac{168}{200} = 0.84, s_E = \sqrt{\frac{0.84(0.16)}{200}} = 0.0259[/tex]
Hence, for the distribution of differences, the mean and the standard error are given as follows:
[tex]p = p_N - p_E = 0.88 - 0.84 = 0.04[/tex]
[tex]s = \sqrt{s_N^2 + s_E^2} = \sqrt{0.023^2 + 0.0259^2} = 0.0346[/tex]
What is the confidence interval?It is given by:
[tex]p \pm zs[/tex]
99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.
Then:
[tex]p - zs = 0.04 - 2.575(0.0346) = -0.049[/tex]
[tex]p + zs = 0.04 + 2.575(0.0346) = 0.129[/tex]
The 99% confidence interval is (-0.049, 0.129).

AA culture started with 4000 bacteria. after 5 hours it grew to 4800 bacteria. Predict how many bacteria will be present after 15 hours. Round your answer to the nearest whole number. p=ae^kt
Answers
Answer:
p = 6912 after 15 hoursp = 4000·e^(0.036463t)Step-by-step explanation:
We want to model the growth of a population of bacteria using an exponential function. We find it convenient to use an "exact" exponential function that relies directly on the numbers given in the problem statement. That function has the form ...
p(t) = (initial population) × (growth factor)^(t/(growth period))
where the "growth factor" is the multiplying factor of the population in period "growth period."
__
Exponential Function (1)Here, the "growth factor" is 4800/4000 = 1.2, and the corresponding "growth period" is 5 hours. Then the population function can be ...
p(t) = 4000×1.2^(t/5)
__
PopulationThe population after 15 hours is ...
p(15) = 4000×1.2^(15/3) = 4000×1.728
p(15) = 6912
__
Exponential Function (2)To change this to the form ae^(kt), we find the value of k to be ...
k = ln(1.2^(1/5)) = ln(1.2)/5 ≈ 0.036463
Then the desired form of the function for p is ...
p(t) = 4000·e^(0.036463t)
_____
Additional comment
In the form p=ae^(kt) the value of k is often rounded to 3 or 4 decimal places. We believe that best accuracy is obtained if k has at least the number of significant digits expected in the answer. Here, the population of almost 7000 has 4 significant digits, so we choose to express k to 5 significant figures. That still gives a small error relative to the first formula that is only "corrected" by rounding the result to an integer.

A. 403 pounds
C. 558 pounds
D. 744 pounds
Answers
Since 1 cubic feet = 62 pounds, the weight of the water that Jerry put in the aquarium is 558 pounds
How to calculate the volume/weight of waterWe have to find the volume of water in the aquarium.
Recall the shape of the aquarium is a rectangular prism. Therefore,
volume = lwh
where
l = lengthw = widthh = heightTherefore,
l = 3 ft
w = 2 ft
h = 1.5 ft
volume = 3 × 2 × 1.5
volume of water = 9 ft³
Therefore,
1 ft³= 62 pounds
9 ft³ = ?
cross multiply
weight of water = 9 × 62
weight of water = 558 pounds

Sonya took out a mortgage of $65,000 at 7% for 25 years. What is the cost of the mortgage?
Answers
The cost of the mortgage is $81250
What are interests?
Interests are percentages of a principal
Given the following parameters
Principal = $65000
Rate = 7% = 0.07
Time = 5 years
I = PRT/100
I = 65000*0.07*25
I = 16,250
Cost of mortgage = Principal + Interest
Cost of mortgage = 65000 + 16250
Cost of mortgage = 81,250
