What is the distance between the points (9.0) and (0,5) on the coordinate plane?
Answers
( x 1 , y 1 ) = ( 9,0 )
( x 2 , y 2 ) = ( 0, 5 )
Distance between the points:
d^2 = ( x2 - x1 ) ^2 + ( y2 - y1 ) ^2
= ( 0 - 9 ) ^2 + ( 5 - 0 )^2
= 81 + 25
= 106
square root both sides, we have:
d = 10 . 296
d = 10. 3 units ( 1 decimal place)

assume the unit population density of a state is approximately 104 people per mi2. if this state has 196,352 square miles, what is the population of the state? people
Answers
Given:
The unit population density of a state is 104 people per mi².
Also, the state has 196,352mi².
Therefore, the population of the state will be the multiplication of the unit population density and the square miles of the state.
Hence,
[tex]\frac{104people}{miles^2^{}}\times196352miles^2=20,420,608people[/tex]Therefore, the population of the state is 20,420,608 people.

There are given that the value of g(x) is:
[tex]g(x)=f(x+8)+4[/tex]Now,
According to the rule of transformation,
y = f(x+c) the function f(x) is being shifted c units left
And, for y=f(x)+d, the function f(x) is being shifed d units up
So,
In the given functiong(x)= f(x+8)+4 the value of c is 8 and value of d is 4
So,
The graph of g(x) is the graph of f(x) shifted 8 units to the left and 4 units up.
Hence, the correct option is A

A school wants to put a bond in the next election, they call this bond Measure K.
They select a random sample of voters in the county and find a 90% confidence interval for the proportion of voters in this county who would vote yes.
Recall that a hypothesis test is used when we want to test an assertion or a claim.
For the given case, there is no assertion or any claim so this is definitely not a hypothesis test.
This is in fact a confidence interval since we are interested in the proportion of voters in this county who would vote yes.
The confidence interval would give us a fair estimate of the true population proportion of voters in this county who would vote yes.
Now coming to whether is it a 1 proportion or 2 proportion confidence interval.
Notice that there is only 1 proportion for the given case that is the proportion of voters in this county who would vote yes.
Therefore, the need to use "1 proportion (z) confidence interval"

Classify the following variables as quantitative or qualitative variables. If the variable is quantitative, identify whether it is discrete or continuous.The daily number of customers in a store.
Answers
A quantitative variable is the one who has a numerical significance such as number of items, time spent on playing a video game while a qualitative variable is the one who has not a numerical significance attached to it such as Gender , Eye color
Further in quantitative variable , discrete variable is the one which is a whole number and can not be broken down further , like number of items
while a continuous variable is the one which takes any value within an interval of values like between 1 and 2 , continuous variable can take any value like 1.21, 1.55556, 1.994 etc.
The daily number of customers in a store can take a whole number value.
Thus, the variable is discrete.

In a right triangle, the side opposite angle θ has a length of 80 inches, the side adjacent to angle θ has a length of 84 inches, and the hypotenuse has a length of 116 inches. What is the value of tan(θ)?
Answers
Solution:
The sides of a right triangle are hypotenuse, opposite, and adjacent.
The hypotenuse is the longest sides of the triangle.
The opposite is the side facing the angle.
The adjacent is the third side of the right triangle.
This sides are illustrated as shown below:
Thus, in the above right triangle ABC,
[tex]\begin{gathered} AC\Rightarrow hypotenuse \\ AB\Rightarrow opposite \\ BC\Rightarrow adjacent \end{gathered}[/tex]Given that the opposite side has a length of 80 inches, adjacent has a length of 84 inches, and the hypotenuse has a length of 116 inches, this implies that
[tex]\begin{gathered} AC=116 \\ AB=80 \\ BC=84 \end{gathered}[/tex]To evaluate the value of
[tex]\tan(\theta)[/tex]We use trigonometric ratios.
From trigonometric ratios,
[tex]\tan\theta=\frac{opposite}{adjacent}[/tex][tex]\begin{gathered} where \\ opposite\Rightarrow AB=80 \\ adjacent\Rightarrow BC=84 \\ thus, \\ \tan(\theta)=\frac{AB}{BC}\frac{}{} \\ =\frac{80}{84}=0.9523809524 \end{gathered}[/tex]Hence, the value of tan (θ) is
[tex]0.952[/tex]The first option is the correct answer.

If you are rolling two dice (numbered 1-6), what is the probability that the first die shows an odd number and the second die shows a number larger than 4?
