Answer:
probability: 0.44
The probability that a student chosen at random will be 16 or older is 0.44 or 44%.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
The probability that a student chosen at random will be 16 or older is the sum of the probabilities of selecting a 16-year-old or older student.
P(16 or older) = P(16) + P(17) + P(18)
P(16 or older) = 0.28 + 0.15 + 0.01
P(16 or older) = 0.44
Therefore, the probability that a student chosen at random will be 16 or older is 0.44 or 44%.

r=1
Step-by-step explanation:
formula for circle= (x-h)^2+(y-k)^2= r^2
(h, k)= center
r= radius
We know that h is 0 since (x-h)^2 is x^2.
We know k= -9 from (y+9)^2
since r^2=1

Answer:
48.2 cm
Step-by-step explanation:
The bottom side of the large triangle has length 78 cm.
The bottom side of the right triangle has length 78 cm/2 = 39 cm.
Now we use the Pythagorean theorem to find the vertical side, the spine.
39² + s² = 62²
s² = 3844 - 1521
s² = 2323
s = 48.2

A model of the Eiffel Tower
uses a scale of 1 cm - 4 meters.
If the model is 75 a centimeters
tall, what is the actual height
of the Eiffel Tower?
Answer:
The correct answer is A. The actual height of the Eiffel Tower is 301 meters.
Step-by-step explanation:
Given that a model of the Eiffel Tower uses a scale of 1 cm - 4 meters, if the model is 75 1/4 a centimeters tall, to determine what is the actual height of the Eiffel Tower the following calculation must be performed:
1 = 4
1/4 = 0.25
75.25 x 4 = X
301 = X
Therefore, the actual height of the Eiffel Tower is 301 meters.

Set up a proportion to find the total number of fl oz from the 6 cups, let variable x be the total oz of the 6 cups:
[tex]\frac{1 cup}{8 oz} = \frac{6 cups}{x oz}[/tex]
The answer should be 48 fl oz, then you add the 4 fl oz to have the total of 52 fl oz.

Answer:
[tex]\tan(30) = \frac{\sqrt 3}{3}[/tex]
[tex]\tan(60) = \sqrt 3[/tex]
Step-by-step explanation:
Given
The attached triangle
Required
Find [tex]\tan(30)[/tex] and [tex]\tan(60)[/tex]
The tangent of an angle is calculated as:
[tex]\tan(\theta) = \frac{Opposite}{Adjacent}[/tex]
So, we have:
[tex]\tan(30) = \frac{b}{a}[/tex]
This gives:
[tex]\tan(30) = \frac{3}{3\sqrt 3}[/tex]
3 cancels out
[tex]\tan(30) = \frac{1}{\sqrt 3}[/tex]
Rationalize
[tex]\tan(30) = \frac{1}{\sqrt 3} * \frac{\sqrt 3}{\sqrt 3}[/tex]
[tex]\tan(30) = \frac{\sqrt 3}{3}[/tex]
Similarly;
[tex]\tan(60) = \frac{a}{b}[/tex]
This gives:
[tex]\tan(60) = \frac{3\sqrt 3}{3}[/tex]
3 cancels out
[tex]\tan(60) = \sqrt 3[/tex]

Answer:
Both are TRUE
Step-by-step explanation:
✔️The statement, "angles 1 and 5 are corresponding angles" is TRUE.
Rationale/reason:
Angles that have corners that match are called corresponding angles. Angles 1 and 5 are angles found in the corners that match each other. Therefore, they are corresponding.
✔️The statement, "Angle 6 is congruent to angle 4" is TRUE.
Rationale/reason:
When two lines that are parallel is crossed by a transversal, the alternate interior angles formed are congruent to each other.
Angles 4 and 6 are interior angles that alternate each other along the transversal. Therefore they are congruent to each other.

Bill washes his mom's car once every 2 weeks and gets paid $20.00 each time. How much does he earn in 22 weeks?
$264.00
$240.00
$176.00
$220.00
Next
Reset
Answer:
Bill earns $220.00 in 22 weeks.
Step-by-step explanation:
If he is paid 20 dollars every 2 weeks for a car wash, we need to find out how many he gets for 22 weeks.
20 dollars = 2 weeks, to find 22, multiply both of the values by 11 to get to 22.
11(2 weeks = 20 dollars)
22 weeks = 220.
The amount of money earned in 22 weeks is $220.
Option D is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The amount for each car wash = $20
Number of car wash in two weeks = 1
Now,
Number of car washes in 22 weeks.
= 22 / 2
= 11
Now,
The amount earned in 11 car washes.
= 11 x 20
= $220
Thus,
Amount earned in 22 weeks is $220.
