Calculate the probability for the following situation: You are tossing a coin, then rolling a die, then drawing a card from a deck of cards. What is the probability that you will get: a head AND an odd number on the die AND a card greater than 3 (assume the ace is equal to 1) from the deck?
Answer:
Flipping the coin:
P( H ) = 1/2
---------------------
Rolling the die:
There are 6 numbers
1,2,3,4,5,6
3 of them are odd, so
P( odd ) = 3/6
P( odd ) = 1/2
Step-by-step explanation:
There are 52 cards in a deck
There are +9%2A4+=+36+
cards less than +10+
P( <10 ) = 36/52
P( <10 ) = 9/13
-----------------
Since you want ALL the above,
multiply probabilities
+%281%2F2%29%2A%281%2F2%29%2A%289%2F13%29+=+9%2F52+

A phone company offers two monthly plans. Plan A costs $15 plus an additional $0.14 for each minute of calls. Plan B has no initial fee but costs $0.18 for each
minute of calls.
Step-by-step explanation:
x = number of minutes
first cost function :
c(x) = 0.14x + 15
the second cost function :
c(x) = 0.18x
I guess, the question (not written in the description) is after how many minutes call time the first plan breaks even with the second plan and further becomes the better choice ?
0.18x = 0.14x + 15
0.04x = 15
x = 15/0.04 = 375
with 375 minutes calling time per month the first plan costs the same as the second plan.
and starting with 376 minutes per month the first plan becomes the cheaper option.
under 375 minutes per month the second plan is the cheaper option.
Which of the following fractions is equivalent to 1.68? A. 25/42 B. 17/25 C. 42/25 D. 7/4
Answer:
42/25 or C
Step-by-step explanation:
Just by looking at the answers, we can eliminate A and B because the equivalent decimals of those would result in a number that is less than one.
Then, you can eliminate D because 7/4 is equal to 1.75
Therefore, your answer would be C, 42/25.
Which of the following functions best describes this graph?
A. y = x^2 + x - 12

Chase found new pants for $35.55 plus 7.5% tax. What is the final price of the new pants?
Answer:
$38.22
Step-by-step explanation:
7.5% of $35.55 = $2.66625
= $2.67
$35.55 + 2.67 = $38.22 after tax
Answer:
$38.22
Step-by-step explanation:
Given the following question:
7.5% of 35.55
To find the answer we must first find 7.5% of 35.55 using the formula to calculate percentages, and then we add that answer to the current price of the pants.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{7.5\times35.55}{100}[/tex]
[tex]7.5\times35.55=266.625[/tex]
[tex]266.625\div100=2.66625[/tex]
[tex]=2.66625[/tex]
Round the answer to the nearest cent:
[tex]2.66625[/tex]
[tex]6 > 5[/tex]
[tex]=2.67[/tex]
7.5% of 35.55 is "$2.67."
Now we add the answer to the current price:
[tex]35.55[/tex]
[tex]35.55+2.67=38.22[/tex]
[tex]=38.22[/tex]
The cost of the new pants after a 7.5% tax is "$38.22."
Hope this helps.

Solution:
We know that:
Given equation: 1/4(x - 2) = 3 - (x + 1/6)Simplify the distributive property.
1/4(x - 2) = 3 - (x + 1/6)=> x/4 - 2/4 = 3 - x - 1/6Further simplify both sides.
x/4 - 2/4 = 17/6 - xSubtract 17/6 both sides.
x/4 - 2/4 - 17/6 = 17/6 - 17/6 - x=> x/4 - 6/12 - 34/12 = -x=> x/4 - 40/12 = -xSubtract x/4 both sides.
x/4 - x/4 - 40/12 = -x - x/4=> -40/12 = -5x/4Use cross multiplication.
=> -160 = -60xDivide -60 both sides.
-160/-60 = -60x/-60=> x = 160/60 = 2 40/60 = 2 2/3Master Mason wants to treat all the
Kids at school. How packs of 15 fudge does he need for 151 children?
Answer:
11
Step-by-step explanation:
you would have to divid 15 from 151
151/15= 10.06
since you cant get a part of a pack you would have to round up which is 11 to treat all of the kids
Answer:
he will need 11 packs of fudge
Step-by-step explanation:
to answer this question you will divide 151 by 15 and you will get 10.066. you cannot bring 0.066 packs of fudge so you would bring one extra meaning you would bring 11 packs total.

Find the exact value of the trigonometric function given that sinU=-7/25 and cosV=-4/5 (Both U and V are in Quadrant III)
sin(V-U)
cos(U-V)
cosU:-
[tex]\\ \rm\longmapsto \sqrt{1-sin^2U}=\sqrt{1-49/625}=24/25[/tex]
As U lies in Q3
cosU=-24/25sinV
[tex]\\ \rm\longmapsto \sqrt{1-cos^2V}=\sqrt{1-16/25}=3/4[/tex]
As V lies in Q3
sinV=-3/5So
sin(V-U)=sinVcosU-cosVsinU=(-3/5)(-24/25)-(-4/5)(-7/25)=72/125-28/125=72-28/125=44/125cos(U-V)=cosUcosV+sinUsinV=(-24/25)(-4/5)+(-7/25)(-3/5)=96/125+21/125=117/125the weight of an apple is 150g, rounded to the nearest 5g. What is the lower bound of the weight of the apple?

Find the sum of the following arithmetic sequence. 4,10,16,22,28
Answer:
Step-by-step explanation:
This is the formula to find the sum of the first
n
terms of the sequence. To evaluate it, the values of the first and
n
the terms must be found .Sn=n2⋅(a1+an)
This is an arithmetic sequence since there is a common difference between each term. In this case, adding
6
to the previous term in the sequence gives the next term. In other words,
an=a1+d(n−1)x Arithmetic Sequence:
d=6 This is the formula of an arithmetic sequence X an=a1+d(n−1)Substitute in the values of a1=4 and d=6 x an=4+(6)(n−1)Simplify each term.
an=4+6n−6 Subtract 6 from 4 x an=6n−2 Substitute in the value of N to find the N the term x a5=6(5)−2 Multiply 6 by 5 x a5=30−2 Subtract 2 from 30 x a5=28 Replace the variables with the known values to find
S5 x S5=52⋅(4+28)Add 4 and 28 x S5=52⋅32
Cancel the common factor of
2.
S5=5⋅16 Multiply 5 by 16 x S5=80
Convert the fraction to a decimal.

28 is what percent of 64?
Solution:
Note that:
64 × x/100 = 28Simplifying the LHS:
64 × x/100 = 28=> 64x/100 = 28Using cross multiplication:
64x/100 = 28=> 64x = 2800Divide 64 both sides.
=> x = 2800/64 = 43.75%28 is 43.75% of 64
