g(x)=3x^2-4 if the graph of g is translated vertically upward by 7 units it becomes the graph of a function f. Find the expression for f(x).
Answers
The expression for f(x) when moving the graph vertically up by 7 units is f(x)=3x²- 6/2.3.
What are expressions?An expression, also known as a mathematical expression, is a finite combination of symbols that are well-formed in accordance with context-dependent rules. An expression in mathematics is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division, etc.) You can think of expressions as being similar to phrases. You must substitute a number for each variable and carry out the arithmetic operations in order to evaluate an algebraic expression.So, the expression for f(x):
We have, g(x)=3x²-4Moving the graph upwards by 7 units vertically, we get the expression for f(x) as:
f(x)=3x²- 6/2.3(Refer to the graph attached below)
Therefore, the expression for f(x) when moving the graph vertically up by 7 units is f(x)=3x²- 6/2.3.

Find the length of the diameter of the circle
with the following equation: (x-4)^2+(y-2)^2=5
Answers
The length of the diameter of the circle is found as the 2×(√5).
What is termed as the equation of the circle?The equation of circle offers an algebraic method for describing a circle given its center and radius length. The equation of a circle differs from the formulas used to calculate a circle's area or circumference. The standard equation for a circle with a radius r and a center at (x1,y1) is: (x−x1)²+(y−y1)²=r².,
For the given question;
The equation of the circle is given as;
(x-4)^2+(y-2)^2=5
Comparing the equation of the circle with the standard form.
Radius r² = 5
Then, r = √5
Now, the diameter is the twice of the radius.
Diameter = 2×radius
Diameter = 2×(√5)
Thus, the length of the diameter of the circle is found as the 2×(√5).

a multiple-choice test has 5 questions, each with 4 choices for the answer and assume only one of the choices is correct. What is the probability you get at least one question correctly?
Answers
The probability that you will get at least one question correctly is 3/4
How to calculate the probability of getting at least one question correctly?Given that the test has 5 questions and 4 choices per question. Therefore:
Total number choices = 5 x 4 = 20 choices
If you are to get at least one question correctly. That means you can either get 1, 2, 3, 4 or 5 questions correctly. Therefore, the probability of getting at least one question correctly will be the sum of the probability of getting 1, 2, 3, 4 or 5 questions correctly:
Note: there are only 5 correct answers and 20 choices
P(1 correct) = 1/20, P(2 correct) = 2/20 = 1/10, P(3 correct) = 3/20, P(4 correct) = 4/20 = 1/5 and P(5 correct) = 5/20 = 1/4
P(at least one question correctly) = P(1 correct) + P(2 correct) + P(3 correct) + P(4 correct) + P(5 correct)
P(at least one question correctly) = 1/20 + 1/10 + 3/20 + 1/5 + 1/4 = 3/4

Answers
Given:
There are given that the slope and the point:
[tex]\begin{gathered} m=-\frac{7}{2} \\ point:\left(-8,-4\right) \end{gathered}[/tex]Explanation:
To find the equation, first, we need to see the formula for slope-intercept form:
So,
From the slope-intercept formula;
[tex]y=mx+b[/tex]Where,
[tex]\begin{gathered} m=-\frac{7}{2} \\ \lparen x,y)=\left(-8,-4\right) \end{gathered}[/tex]Now,
We need to find the value of b by using given information:
So,
Put all the given values into the given slope-intercept form:
[tex]\begin{gathered} y=mx+b \\ -4=-\frac{7}{2}\left(-8\right)+b \\ -4=28+b \\ b=-32 \end{gathered}[/tex]Then,
Put the value of b and m into the slope-intercept form;
So,
[tex]\begin{gathered} y=mx+b \\ y=-\frac{7}{2}x+\left(-32\right) \\ y=-\frac{7}{2}x-32 \end{gathered}[/tex]Final answer:

Answers
The equation of a line is given by
[tex]y-y_1=m(x-x_1)[/tex]where m is the slope of the line and (x1,y1) is a point where the line passes through.
In our case we have a point but we don't have the slope yet, so we have to find it. To do this we have to remember that two lines are parallel if and only if their slopes are equal, that is
[tex]m_1=m_2[/tex]We know that the line we are looking for is parallel to the line
[tex]y=13x-4[/tex]we notice that this line in written in the slope-intercept form
[tex]y=mx+b[/tex]then its slope is 13.
Since the line is parallel to the one we are looking for, our slope is also 13.
Using the point (9,12) and the slope the equation of the line is
[tex]y-12=13(x-9)[/tex]now we have to write in the slope-intercept form
[tex]\begin{gathered} y-12=13x-117 \\ y=13x-117+12 \\ y=13x-115 \end{gathered}[/tex]Therefore the line is

Using the normal distribution, it is found that:
a) The variable used in this problem is: The time (in hours) a 4-year old spends unsupervised per day.
b) The distribution is: X ~ N(3, 1.8).
c) The probability is P(X < 1) = 0.1335, and is given by the bottom left graph.
d) The percentage of children who spend over 10 hours a day unsupervised is of 0.01%.
e) 90% of the children spend at least 0.7 hours unsupervised.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is given by the following rule:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure X is above or below the mean, depending if the z-score is positive or negative.From the z-score table, the p-value associated with the z-score is found, and it represents the percentile of the measure X.The variable used in this problem is:
The time (in hours) a 4-year old spends unsupervised per day, as the distribution involves only 4-year old children, and the mean and the standard deviation are measured in hours.
The mean and the standard deviation of the distribution are given, respectively, by:
[tex]\mu = 3, \sigma = 1.8[/tex].
Hence the distribution can be described approximately as follows:
X ~ N(3, 1.8).
The probability that a person spends less than 1 hour a day unsupervised is the p-value of Z when X = 1, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (1 - 3)/1.8
Z = -1.11
Z = -1.11 has a p-value of 0.1335.
The bottom left graph shows this probability, as the number in hours cannot be less than 0(there is no negative number of hours).
The proportion of children who spends over 10 hours a day unsupervised is one subtracted by the p-value of Z when X = 10, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (10 - 3)/1.8
Z = 3.89
Z = 3.89 has a p-value of 0.9999
1 - 0.9999 = 0.0001, hence the percentage is of 0.01%.
For item e, the measure is the 10th percentile, which is X when Z = -1.28, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
-1.28 = (X - 3)/1.8
X - 3 = -1.28 x 1.8
X = 0.7 hours.
