What is the probability of obtaining a prime number and a head?
Step-by-step explanation:
coin = 50%
dice = 3/6 or 50%
hope this helps
Using it's concept, it is found that there is a 0.25 = 25% probability of obtaining a prime number and a head.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem:
For the dice, 3 out of 6 outcomes are prime(2, 3 and 5), hence P(A) = 3/6 = 0.5.For the coin, 1 out of 2 outcomes is heads, hence P(A) = 1/2 = 0.5.The events are independent, hence the probability of both is given by:
P(A and B) = P(A) x P(B) = 0.5 x 0.5 = 0.25.
0.25 = 25% probability of obtaining a prime number and a head.

Terry has a credit card that uses the average daily balance method. For the first 18 days of one of his billing cycles, his balance was $350
Complete question:
Terry has a credit card that uses the average daily balance method. For the first 18 days of one of his billing cycles, his balance was $350, and for the last 12 days of the billing cycle, his balance was $520. If his credit card's APR is 14%, which of these expressions could be used to calculate the amount Terry was charged in interest for the billing cycle?
(0.14/365 31)(18 $350 + 12 $520 / 31)
(0.14/365 30)(18 $350 + 12 $520 / 30)
(0.14/365 30)(12 $350 + 18 $520 / 30)
(0.14/365 31)(12 $350 + 18 $520 / 31)
Answer:
(0.14/365 30)(18 $350 + 12 $520 / 30)
Step-by-step explanation:
Number of days in a year = 365
Number of days in billing cycle = (18 + 12) = 30
Interest rate per year = 14% = 0.14
Amount charged monthly :
(Monthly rate × average daily balance)
MONTHLY RATE:
(Annual interest / number of days in year) * days in billing cycle
(0.14 / 365) × 30
Average daily balance :
First 18 days ; balance = $350
Last 12 days ; balance = $520
Sum of balance / days in billing cycle
[(18 × $350) + (12 × 520)] / 30
THEREFORE, MONTHLY INTEREST CHARGE :
((0.14 / 365) × 30) ((18 × $350) + (12 × 520) / 30)
A fair dice and unbaised coin are tossed once.what is the probability of obtaining 3 and a tail
Answer:
1/4 & 1/2
Step-by-step explanation:
4 sides to the dice
2 sides to coin
Answer:1/12
Step-by-step explanation:
The probability of getting a three on a fair die is 1/6
The probability of getting tails on an unbiased coin is 1/2
Then the probability of getting a three on a fair die and tails on an unbiased coin is 1/6 x1/2=1/12

Raina runs each lap in 7 minutes. She will run more than 63 minutes today. What are the possible numbers of laps she will run today? Use n for the number of laps she will run today. Write your answer as an inequality solved for n.
Answer:
n >or= 9
n greater than or equal to 9
Step-by-step explanation:
Raina runs each lap for 7 minutes
Each lap=7 minutes
She will run more than 63 minutes today
n laps=63minutes(at least)
n =63/7
n =9(at least)
n >or= 9
n greater than or equal to 9
It means Raina will run at least 9 laps or more today

Ashley and Beth drove from city A to city B in exactly 5 hours, not taking rest stops. Ashley drove up to the area located halfway between the two cities at the average speed of 40 miles per hour and then Beth drove the other half at an average speed of 60 miles per hour. How many hours did Beth drive on their trip?
Answer:
2 hours
Step-by-step explanation:
Time= 5 hrs
Ashley's speed= 40 mph
Beth's speed= 60 mph
Beth's time in travel= x
Since they drove the same distance, we have this equation:
60x=40(5-x)60x=200-40x100x=200x=200/100x=2 hoursAt the beach, 11% of people have white towels and 53% have blue towels. If
the rest have red, what percentage of the people at the beach have red
towels?
Answer here
SUBMIT
ASAP help plz
Answer:
36 percent.
Step-by-step explanation:
We have been given that 11 percent of people of the peach have white towels, and 53 percent have blue towels.
With this information, we can find the remaining percentage of people that have red towels.
Recall that the total percentage is always 100 percent.
lets make r for the percentage of people that have red towels.
You can solve it by changing it to fraction, decimal, or just keep it at percent.
I will show you all of the possible ways.
Percent:
11 percent plus 53 percent plus r =100 percent
combine the like terms, or add 11 plus 53 to simplify the equation.
You have 64 percent plus r =100 percent Our goal is to isolate r, so subtract both sides by 64 percent.
100-64 is 36 percent.
r=36 percent of people who have red towels.
With fractions.
Write it as 11/100 plus 53/100 plus r/100= 100/100.
Combine the fractions.
64/100 plus r/100=100/100.
Subtract both sides by 64/100.
You are left with r=36/100, 9/25, or 36 percent.
With decimals.
11 percent as a decimal is 0.11. Just move the decimal spot 2 times. In 11, since you can write it as 11.0, you move it to the right twice.
53 percent is 0.53.
r is r.
100 percent is 1.
0.11 plus 0.53 plus r=100
Combine or add 0.53 and 0.11. That is 0.64.
Subtract both sides by 0.64.
You get r to be 0.36 or 36 percent.
I hope this helps, and I hope you have a good day!

Option B
Step-by-step explanation:
Complementary Angles add up to 90 degrees
So,

What is the decimal multiplier to decrease by 15%?
Explanation:
If we start off with $100 and decrease by 15%, then we are decreasing by $15 since 15% of 100 = 0.15*100 = 15
We start with $100 and drop to 100-15 = 85. Dividing this over the original 100 gets us 85/100 = 0.85
Put another way, 100% - 15% = 1 - 0.15 = 0.85
The decimal multiplier for "decrease by 15%" is 0.85; this sort of thing is useful if you wish to apply multiple discounts to a product.
Side note: the 0.85 can be thought of as 85%, so the product's new value is 85% of its original value

Answer:
fail 0-x. mid values. =X/2
pass x-a. =(x+a)/2. pass no.=250-35-15-23=177
credit a-y. =(a+y)/2
distinction y-100. =(y+100)/2

Q7 Calculate the volume of a
sphere with diameter of 4.2mm.
Answer: 38.79 cu. mm.
Step-by-step explanation:
Volume = 4/3π x r^3
= 4/3π x 2.1^3
= 4/3 x 22/7 x 9.261
= 38.79
Answer:
38.792 or 38.808
Step-by-step explanation:
Formula for Volume of Sphere = 4 x pi x 1/3 x r cubed
So,
if diameter = 4.2, then radius = 4.2 divided by 2 = 2.1
Now, volume =
4 x 22/7 x 1/3 x 2.1^3 = 38.808
But is you used 3.14 as pi,
then the volume = 38.792

Line segments XY and ZY are tangent to circle O. Circle O is shown. Triangle X Y Z has points X and Z on the circle. Lines X Y and Z Y are tangents that intersect at point Y outside of the circle. Which kind of triangle must triangle XYZ be? an equilateral triangle an isosceles triangle a scalene triangle a right triangle
Answer:
The correct option is;
An isosceles triangle
Step-by-step explanation:
The parameters given are;
Line segments XY and ZY are tangents to circle O.
ΔXYZ has points X and Z on the circle.
XY and ZY are tangents that intersect at point Y outside the circle'
Therefore, given the circle has center O, then;
OY ≅ OZ = Radius of circle with center O
∠OXY ≅ ∠OZY = 90° (The radius line from the circle center to the tangent point is perpendicular)
OY ≅ OY (Reflexive property)
ΔOYX and ΔOYZ are right triangles (Triangle with one angle = 90°
ΔOYX ≅ ΔOYZ (Hypotenuse Leg, HL, rule of congruency)
Therefore;
XY = ZY (Corresponding Parts of Congruent Triangles are Congruent CPCTC)
Triangle XYZ is an isosceles triangle (Triangle with two equal sides).

Triangle P Q R is shown. Angle Q P R is a right angle. The length of Q P is 8 StartRoot 3 EndRoot and the length of P R is 8. Consider triangle PQR. What is the length of side QR? 8 units 8 StartRoot 3 EndRoot units 16 units 16 StartRoot 3 EndRoot units
Answer:
Length of side QR is 16 units.
Step-by-step explanation:
Given that dimensions of [tex]\triangle PQR[/tex] are as follows:
[tex]\angle QPR =90^\circ[/tex]
Side QP [tex]= 8 \sqrt3\ units[/tex]
Side PR = 8 units
To find, side QR = ? units
Please refer to the attached figure for the representation of the given dimensions.
Base is side QP,
Perpendicular is side PR and
Hypotenuse is side QR.
In a right angled triangle, Pythagorean theorem holds true i.e.
Accoring to pythagoras theorem:
[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}[/tex]
[tex]\Rightarrow QR^{2} = QP^{2} + PR^{2}[/tex]
Putting the values of QP and PR:
[tex]\Rightarrow QR^{2} = (8\sqrt3)^{2} + 8^{2}\\\Rightarrow QR^{2} = 64 \times 3+ 64\\\Rightarrow QR^{2} = 64 \times 4\\\Rightarrow QR = 8 \times 2\\\Rightarrow QR = 16\ units[/tex]
So, the value of length of side QR is 16 units.

For what value of the variable: is the value of 9−y twice as much as the value of y?
Answer:
y = 3

9 = 3y Divide both sides by 3
3 = y When y = 3, the value of 9 - y is twice the value of y.
