Answer:
Step-by-step explanation:
True
The given statement "Scientific Notation is made up of two number parts. The second part is a power of base 10" is True so option (A) will be correct.
What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.
Scientific Notation of any random number abcd is given by a.bcd × 10^something.
So the second part will definitely 10^something.
For example, the scientific notation of 345 is 3.45 × 10².
Hence "Scientific Notation is made up of two number parts. The second part is a power of base 10".

Solving the equation
Answer:
y = 5
Step-by-step explanation:
Step 1: Write equation
-(4y + 2) - (-3y - 6) = -1
Step 2: Solve for y
Distribute: -4y - 2 + 3y + 6 = -1Combine like terms: -y + 4 = -1Subtract 4 on both sides: -y = -5Divide both sides by -1: y = 5Step 3: Check
Plug in y to verify it's a solution.
-(4(5) + 2) - (-3(5) - 6) = -1
-(20 + 2) - (-15 - 6) = -1
-22 - (-21) = -1
-22 + 21 = -1
-1 = -1
Evaluate 8+3e when e=2
Answer:
14
Step-by-step explanation:
8 + 3e
e = 2
substitute in the given value
8 + 3(2)
simplify
8 + 6
14
Answer: 14
Step-by-step explanation: Here, we have the expression 8 + 3e
and we want to evaluate the expression when e = 2.
To evaluate an expression, we simply plug the
value of the variable into the expression, and solve.
So here, since e = 2, we have 8 + 3(2).
3(2) is equal to 6 so we have 8 + 6, which is equal 14.
It’s a good idea to get into the habit of using parentheses
when substituting numbers in for variables.
So the value of our expression when e = 2 is 14.
A blueprint for a building includes a rectangular room that measures 3 inches long and 7.5 inches wide The scale for the blueprint says that 1 inch on the blueprint is equivalent to 10 feet in the actual building. What are the dimensions of this rectangular room in the actual building?
3 · 7.5 = 22.5: 22.5 is the area of the building on the blueprint in inches
22.5 · 10 = 225 feet squared is the area of the building in real life.

Answer:
i think its A and D
Step-by-step explanation:
Solve the equation. Then check your solution. 6 = negative 2 (10 n + 7)
n = - 1
Step-by-step explanation:Hi !
6 = - 2(10n + 7)
6 = - 20n - 14
20n = - 6 - 14
20n = - 20
n = - 20 : 20
n = - 1
6 = - 2(10×-1 + 7)
6 = - 2(-10 + 7)
6 = - 2(-3)
6 = 6 (true)
Good luck !
Answer:
n = -1 OR -1 = n
Step-by-step explanation:
6 = -2(10n +7)
First we remove the brackets by multiplying the inner numbers by -2
6 = -20n - 14
Then we add 14 on both sides
20 = -20n
We make n the subject and divide both sides by -20
n = -1 OR -1 = n
Find the (a) mean, (b) median, (c) mode, and (d) midrange for the data and then (e) answer the given questions.
Listed below are selling prices (dollars) of TVs that are 60 inches or larger and rated as a "best buy" by a popular magazine. Are the resulting statistics representative of the population of all TVs that are 60 inches and larger? If you decide to buy one of these TVs, what statistic is most relevant, other than the measures of central tendency?
1550 1650 1600 1650 1500 1200 1650 1800 1200 1050 1650 1850
Answer:
Step-by-step explanation:
a) Mean the sum total of the given variables divided by the sample size given.
Mean = (Σx)/N
Σx = 1550 +1650 +1600 +1650 +1500 +1200 +1650+ 1800+ 1200 +1050 +1650+ 1850
Σx = 18,350
N = 12
Mean = 18,350/12
Mean = 1529.17
b) Median is the data at the middle if the given dataset after rearrangement. Arrangement can either be in ascending or descending order.
Rearranging the dataset in ascending order of magnitude.
1050 1200 1200 1500 1550 (1600 1650) 1650 1650 1650 1800 1850
It is seen that two values 1600 and 1650 are values that falls in the middle, hence we will take their average.
Median = 1600+1650/2
Median = 1625
c) Mode is the value in the dataset that occur the most i.e value with the highest frequency. According to the data only 1650 occurs 4 times, hence the mode of the data is 1650.
d) Midrange of the data is the average of the highest values and the Lowest value.
Midrange = Maximum value+Minimum value/2
Max value = 1850
Min value = 1050
Midrange = 1850+1050/2
Midrange = 2900/2
Midrange = 1450
4) No, the resulting statistics are not representative of the population of all TVs that are 60 inches and larger because it is given that the dataset provided is for the selling prices of TVs that are 60 inches or larger and rated as a "best buy" by a popular magazine, therefore we can conclude that, the dataset is representative of the best type of TVs that are 60 inches and larger and not all the sets of TVs
- The measure of dispersion relevant is the STANDARD DEVIATION other than the measures of central tendencies above because it shows how the selling prices of the different best TVs varies especially that of variation from the mean.

2. The probability of a success must remain constant in a binomial experiment.
(a) Explain why this is true.
(b) How does this relate to the requirement of independence in a binomial experiment?
Answer:
It takes about 18m
Step-by-step explanation:
An experiment is said to be binomial in nature if and only if it obeys the following conditions which include :
Fixed number of trials Each trial must be independent Only two possible outcomes Probability of success on each trial is the same.When an experiment obeys these conditions, then it can be adjudged to be a binomial experiment.
The probability of success on each trial must the same, this also allows the probability of failure to be the same throughout the experiment since there are only two possible outcomes on each trial and the outcomes are equally likely. Independence in a binomial experiment entails that, each individual trial does not depend on the result or outcome of the previous trial, since the probability of success is constant all through the experiment, then independence of each trial is a necessary prerequisite for a binomial experiment.Hence, a binomial experiment must meet the four listed requirements.

Use the LCD to rewrite the 1/6 and 3/8 with the same denominator.
Answer:
1/6 becomes 4/24 and 3/8 becomes 9/24.
Step-by-step explanation:
The LCD of the denominators is 24 because that is the lowest number that 6 and 8 are both related too (6 times 4 is 24, and 8 times three is 24). Since 6 goes into 24 4 times, multiply 1 (the numerator) by 4 and you get 4. Since 8 goes into 24 3 times, multiply 3 (the numerator) by 3 and you get 9.

Find the slope of the line that is perpendicular to the line that passes through the points (5,2) and (8,1)
Answer:
3
Step-by-step explanation:
The slope of the line passing through the points is
m = (y2-y1)/(x2-x1)
= ( 1-2)/(8-5)
= -1/3
The slope that is perpendicular is the negative reciprocal which is
- ( 1/(-1/3)
+ 3/1
The perpendicular slope is 3

Calculate the standard deviation. Variance = 107.76. Mean = 34.2
(Round up to the second decimal point.)
Answer:
The standard deviation is 10.38
Step-by-step explanation:
Given;
Variance, v = 107.76
mean, x = 34.2
The standard deviation is given by;
standard deviation = √variance
standard deviation = √107.76
standard deviation = 10.381
standard deviation = 10.38 (two decimal places)
Therefore, the standard deviation is 10.38
does A line segment always contains a line?
Answer:
In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints

Answer:
29 degrees
Step-by-step explanation:
Note how both triangles are isosceles triangles, which mean two angles will be equivalent. In the triangle with the marked angle measurement, since the total of angles in a triangle is 180, then the measurement of the unmarked angles have a sum of 180-64, which is 116. Then, as stated before, this triangle is isosceles, so the measurement of each unmarked angle is 116/2, which is 58.
Next, notice how the angle below angle x in that triangle shares a line with one of the 58 degree angles. This means that angle is 180-58, which is 122. Now, since the total of angles in a triangle is 180 and the triangle is isosceles, then angle x is (180-122)/2, which is 58/2, or 29 degrees
