Answer:

Yes

Step-by-step explanation:

To be a function, the graph must pass the vertical line test.

The vertical line test is simple. Imagine you draw an infinite number of vertical lines. In all of these lines, it should never hit the function twice in the same x value.

For example, if it hits (4, 2) and (4, 7), the graph is not a function because there are two points with the same x value.

A positive integer from one to six is to be chosen by casting a die. Thus the elements c of the sample space C are 1, 2, 3, 4, 5

Alex_Xolod [135]

Answer with Step-by-step explanation:

We are given that six integers 1,2,3,4,5 and 6.

We are given that sample space

C={1,2,3,4,5,6}

Probability of each element= $\frac{1}{6}$

We have to find that $P(C_1),P(C_2),P(C_1\cap C_2) \;and\; P(C_1\cup C_2)$

Total number of elements=6

$C_1$ ={1,2,3,4}

Number of elements in $C_1$ =4

$P(E)=\frac{number\;of\;favorable \;cases}{Total;number \;of\;cases}$

Using the formula

$P(C_1)=\frac{4}{6}=\frac{2}{3}$

$C_2$ ={3,4,5,6}

Number of elements in $C_2$ =4

$P(C_2)=\frac{4}{6}=\frac{2}{3}$

$C_1\cap C_2$ ={3,4}

Number of elements in $(C_1\cap C_2)=2$

$P(C_1\cap C_2)=\frac{2}{6}=\frac{1}{3}$

$C_1\cup C_2=$ {1,2,3,4,5,6}

$P(C_1\cup C_2)=\frac{6}{6}=1$

Ravi and his wife are each starting a saving plan. Ravi will initially set aside $125 and then add $40.75 every week to the savi

katen-ka-za [31]

Answer:

T = 125 +116.40N

Step-by-step explanation:

The total savings is the sum of the two plan values:

T = A + B

T = (125 +40.75N) +(75.65N) . . . . substitute the given formulas

T = 125 + (40.75+75.65)N . . . . . . .combine like terms

T = 125 +116.40N

A cellphone company charges $60 for a cellphone and a monthly rate to use the phone.Regina will pay $1,140 for a 24-month cellph

Alinara [238K]

The monthly rate is $45 for this cellphone plan.

Step-by-step explanation:

Given,

Amount charged for cell phone = $60

Amount paid by Regina for 24 month plan = $1140

Number of months = 24

Let,

m be the monthly rate for cellphone plan

Number of months * Monthly rate + cellphone charges = Amount paid

$24m+60=1140\\24m=1140-60\\24m=1080$

Dividing both sides by 24

$\frac{24m}{24}=\frac{1080}{24}\\m=45$

The monthly rate is $45 for this cellphone plan.

Please answer all questions thank you.

1) 78.5/pi = 25
radius = 5
The one 5 digits away from that coordinate is (2,-1)

2) This question is area, not perimeter. The width and length has to be added by 4 because of 2 feet on both sides.
9*10 = 90 - 30 = 60

3) 25pi according to pythagorean theorem.
