At a large high school, 15% of the students drive to school. Of the students that drive to school, 80% are seniors. What is the probability a randomly selected
student drives to school and is a senior?
O 0.19
O 0.65
O 0.95
O 0.12
Answer:
0.12
Step-by-step explanation:
Probability is defined as the number of possible outcomes divided by the total outcome.
Given that 15% of the students drive to school and of the students that drive to school, 80% are seniors then the probability a randomly selected student drives to school and is a senior P(D&S)
= 15% * 80%
= 15/100 * 80/100
= 0.12
The 4th option
This question is based on the concept of probability. Therefore the correct option is (D), that is 0.12 is the probability a randomly selected student drives to school and is a senior.
Given:
At a large high school, 15% of the students drive to school. Of the students that drive to school, 80% are seniors.
We have to calculated the probability a randomly selected student drives to school and is a senior.
By the definition of probability,
Probability is branch of mathematics, and it is defined as the number of possible outcomes divided by the total outcome.
Given that, 15% of the students drive to school and of the students that drive to school, 80% are seniors.
Hence, the probability a randomly selected student drives to school and is a senior is ,
[tex]=\dfrac{15}{100} \times \dfrac{80}{100}\\\\= 0.15 \times 0.8\\\\= 0.12[/tex]

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
There are 75 pieces of candy in a 15 oz bag.
So, Per ounce the amount of candy
= 75/ 15
= 5
Hence, In 1 ounce there are 5 piece of Candy.

Is this a function ?
If f(x) is an exponential function where f(2.5)=26 and f(6.5)=81, then find the value of f(12), to the nearest hundredth.
Given:
f(x) is an exponential function.
[tex]f(2.5)=26[/tex]
[tex]f(6.5)=81[/tex]
To find:
The value of f(12), to the nearest hundredth.
Solution:
The general exponential function is
[tex]f(x)=ab^x[/tex]
For, x=2.5,
[tex]f(2.5)=ab^{2.5}[/tex]
[tex]26=ab^{2.5}[/tex] ...(i)
For, x=6.5,
[tex]f(6.5)=ab^{6.5}[/tex]
[tex]81=ab^{6.5}[/tex] ...(ii)
Divide (ii) by (i).
[tex]\dfrac{81}{26}=\dfrac{ab^{6.5}}{ab^{2.5}}[/tex]
[tex]\dfrac{81}{26}=b^4[/tex]
Taking 4th root on both sides, we get
[tex]\sqrt[4]{\dfrac{81}{26}}=b[/tex]
[tex]b\approx 1.32855[/tex]
Putting b=1.32855 in (i), we get
[tex]26=a(1.32855)^{2.5}[/tex]
[tex]26=a(2.03444)[/tex]
[tex]\dfrac{26}{2.03444}=a[/tex]
[tex]a\approx 12.7799[/tex]
Now, the required function is
[tex]f(x)=12.7799(1.32855)^x[/tex]
Putting x=12, we get
[tex]f(12)=12.7799(1.32855)^{12}[/tex]
[tex]f(12)=386.4224[/tex]
[tex]f(12)\approx 386.422[/tex]
Therefore, the value of f(12) is 386.422.

Answer:
A) No solution.
B) -2, 1, 2
C) 2, 1, - 2
D) Infinite number of solutions
Step-by-step explanation:
A) 2x + 5y - z = -2
3x - 2y + z = 4
-x + 7y - 2z = 2
Let's add eq(1) and eq(2) to eliminate z.
2x + 3x + 5y - 2y - z + z = -2 + 4
5x + 3y = 2 - - - (eq 4)
Let's multiply eq(2) by 2 and add to eq(3) to eliminate z.
6x - x - 4y + 7y + 2z - 2z = 8 + 2
5x + 3y = 6 - - -(eq 5)
Subtracting eq(4) from eq(5) gives;
0 = 4
This is inconsistent and thus the system of equation has no solution.
B) 4x + 5y + 3z = 3
-3x + 4y - z = 8
5x + 3y + 2z = -3
Multiply eq 2 by 3 and add to eq 1 to eliminate z;
4x - 9x + 5y + 12y + 3z - 3z = 3 + 24
-5x + 17y = 27 - - - (eq 4)
Multiply eq 2 by 2 and add to eq 3 to eliminate z;
5x - 6x + 3y + 8y + 2z - 2z = -3 + 16
-x + 11y = 13 - - - (eq 5)
Multiply eq (5) by -5 and add to eq 4 to get;
17y - 55y = 27 - 65
-38y = - 38
y = 1
Putting 1 for y in eq 5 gives; x = -2
Putting x = - 2 and y = 1 in eq 1 gives;
z = 2
C) 4x - 3y + 2z = 1
-2x + 3y - 2z = 3
2x - 3y + 3z = -5
Solving this equation simultaneously via a calculator gives;
x = 2, y = 1, z = - 2
D) 2x + 3y - z = -2
x - 9y + 2z = 8
-x - 12y + 3z = 10
Add eq(2) to eq (3) to get;
-21y + 5z = 18 - - - (eq 4)
Multiply eq 2 by 2 and add to eq 3 to get;
-30y + 7z = 26 - - - (eq 5)
From eq 4, z = (18 + 21y)/5
Put this in eq 5 to get;
-30y + 7(18 + 21y)/5 = 26
-30y + 126/5 + 147y/5 = 26
Solving this leads to infinite number of solutions
X/3 - 6 > -12 I need help!
Answer:
x > -18
Step-by-step explanation:
If x was -18, -18/3 is -6 and -6-6 is -12. So, x must be greater than -18.
Answer:
x>-18
Step-by-step explanation:
Inequality answers are same as algebra but we use < or > for more than or less than and with line under for equal to.
x/3 -6 >-12
x/3 > -12 +6
x/3 > -6
x>-6 x 3

A frame designer is making a triangular frame. She has two sides of length 18 inches and 27 inches. What are the possible lengths (in whole inches) for the third side?
Answer:
Therefore, the possible lengths (in whole inches) for the third side is
9 inches < x < 45 inches
Step-by-step explanation:
For the above question, we have a rule, the sum of the length of any two sides of the triangle must be greater than the length of the third side.
Hence:
She has two sides of length 18 inches and 27 inches
Let the third side = x
Hence:
a) 18 + 27 > x
45 > x
b) 18 + x > 27
x > 27 - 18
x > 9
Therefore, the possible lengths (in whole inches) for the third side is
9 inches < x < 45 inches

A household item uses 321 watts of electricity. This item is used for 27 hours each week. How much CO2 will be produced each week from this item?
This question is incomplete, the complete question is;
A household item uses 321 watts of electricity. This item is used for 27 hours each week. How much CO2 will be produced each week from this item? (assume 1.37 pounds of CO2 is produced per KWH of electricity used)
Answer: 11.87 lbs of CO2 will be produced each week from this item
Step-by-step explanation:
Given that;
Average wattage Wattage of the item = 321 watts
Time used = 27 hours each week
CO2 produced each week = ?
so;
Total electricity consume = 321 × 27 = 8667 watt = 8.667 kWh
given that; 1.37 pounds of CO2 is produced per KWH of electricity used
hence; CO2 generated by our item will be;
⇒ 8.667 kWh × 1.37
= 11.87 lbs
Therefore, 11.87 lbs of CO2 will be produced each week from this item

Write the ratio of the first measurement to the second measurement. Compare in millimeters. Diameter of ball A:33 mm. Diameter of ball B: 5.4 cm
Answer:
the ratio of the first measurement to the second measurement is 11 / 18 or 11 : 18
Step-by-step explanation:
Given that;
diameter measurement of ball A = 33 mm
diameter measurement of ball B = 5.4 cm
Now, we convert the unit of measurement of ball B from centimeter to millimeter
we know that 1 cm = 10 mm
so 5.4 cm = x mm
x mm = 5.4 × 10 = 54 mm
therefore, diameter measurement of ball B is 54 mm.
Now, the ratio of the first measurement to the second measurement will be;
⇒ 33 / 54
we simplify the fraction
⇒ 11 / 18 or 11 : 18
Therefore, the ratio of the first measurement to the second measurement is 11 / 18 or 11 : 18
