If a player is standing 10 feet from the net, he could make approximately option (b) 5 baskets.

What is Distance?

A basketball player recorded the number of baskets he could make depending on how far away he was standing from the net.

The distance from the net in feet is plotted against the number of baskets made.

Now, we see from the graph that when the distance from the net in feet is 10, the ordinate of the point is 5.

So, he could make approximately 5 baskets.

So, the answer is

Using the best fit line, if a player is standing 10 feet from the net, he could make approximately option (b) 5 baskets.

If A,B, and C are the letters selected and we use A twice, B twice, and C once. The number of ways different passwords exist in this scenario are 30.

A password, sometimes known as a passcode (in devices made by Apple, for instance), is a hidden piece of information that is typically a long string of characters and is used to verify a user's identity. Passwords were always thought to be memorized, but today's average person has access to a huge number of password-protected services, making it difficult to remember a different password for each one. The secret is kept by a party known as the claimant, and the person confirming the claimant's identity is known as the verifier, according to the nomenclature of the NIST Digital Identity Guidelines. The verifier can determine the identity of the claimant when the claimant successfully uses a recognized authentication technique to show the verifier that they know the password.

The interval where the systolic pressure will be lowest is from 12 PM to 2 PM.

What are the domain and ranges of a function ?

The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes.

A function S(t) is defined for systolic pressure.

S(t) = { 140 - 6t , for 0 ≤ t ≤ 4 }

S(t) = { 116 , for 4 < t < 8 }

S(t) = {96 + 8t , for 8 ≤ t ≤ 12 }

Let's find the values of systolic pressure [tex]S(t)_{min}[/tex] for each cases.

When , 0 ≤ t ≤ 4

[tex]S(t)_{min}[/tex] = 140 - ( 6 × 4 )

[tex]S(t)_{min}[/tex] = 140 - 24

[tex]S(t)_{min}[/tex] =  116

When , 4 < t < 8

[tex]S(t)_{min}[/tex] =  116

When , 8 ≤ t ≤ 12

[tex]S(t)_{min}[/tex] = 96 + ( 8 × 8)

[tex]S(t)_{min}[/tex] =  96 + 64

[tex]S(t)_{min}[/tex] =  160

So , the lowest value of S(t) will be 116 for for 4 < t < 8  and interval will be from 12 PM to 2 PM.

Therefore , the interval where the systolic pressure will be lowest is from 12 PM to 2 PM.

UV = 12

Step-by-step explanation:

SV = ST + TU + UV ( substitute values )

4x - 29 = 13 + 6 + 2x - 18

4x - 29 = 1 + 2x ( subtract 2x from both sides )

2x - 29 = 1 ( add 29 to both sides )

2x = 30 ( divide both sides by 2 )

x = 15

Then

UV = 2x - 18 = 2(15) - 18 = 30 - 18 = 12

Answer:

Answer:

(- 4, 2 )

Step-by-step explanation:

y = 3x + 14 → (1)

2x - 3y = - 14 → (2)

substitute y = 3x + 14 into (2)

2x - 3(3x + 14) = - 14 ← distribute parenthesis on left side and simplify

2x - 9x - 42 = - 14

- 7x - 42 = - 14 ( add 42 to both sides )

- 7x = 28 ( divide both sides by - 7 )

x = - 4

substitute x = - 4 into (1)

y = 3(- 4) + 14 = - 12 + 14 = 2

solution is (- 4, 2 )

The quantity 3.185 times ten raised to the seventeenth power end quantity divided by the quantity 9.1 times ten raised to the eighth power end quantity written in scientific notation is 0.35 x 10^9. option B

The electronic configuration of chlorine (Cl) is

2,8,7

This means Cl needs only one electron to complete its octet configuration

and

The electronic configuration of sulfur (S) is

2,8,6

This means sulfur needs two more electrons to complete its octet configuration

Since chlorine needs fewer electrons to complete its octet configuration, then it will be more likely to attract electrons.

If Javier paid $92 for 5 notebooks and 3 pencils and Laura paid $56 for 2 notebooks and 6 pencils, then the price of each notebook is $16 and that of each pencil is $4, calculated using linear equations.

As per question statement, Javier paid $92 for 5 notebooks and 3 pencils while Laura paid $56 for 2 notebooks and 6 pencils.

We are required to calculate the price of each notebook and each pencil.

To solve this question, let us assume that the price of each notebook is  "x" and that of each pencil is "y". Now, we will form two linear equations, each with the two assumed variables, based on the conditions mentioned in the question statement, and solving the equations, we will obtain our desired answer.

Since Javier bought 5 notebooks and 3 pencils for $92 and the price of each notebook is assumed to be "x" and that of each pencil is assumed to be "y", we can write that

[tex][(5x+3y)=92]...(1)\\or,5x = 92-3y\\or,x=\frac{(92-3y)}{5}...(2)[/tex]

And in Laura's case, she bought 2 notebooks and 6 pencils for $56, i.e.,

[tex][(2x+6y)=56]...(3)\\or, 2(x+3y)=56\\or, (x+3y)=\frac{56}{2}\\ or,(x+3y)=28\\or,x=(28-3y)...(4)[/tex]

Now, equating (2) and (4), we get,

[tex]x=\frac{(92-3y)}{5}=(28-3y)\\ or, \frac{(92-3y)}{5}=(28-3y)\\ or, (92-3y)=5(28-3y)\\or, 92-3y=140-15y\\or,(15y-3y)=140-92\\or,12y=48\\or,y=\frac{48}{12}=4[/tex]i.e., Price of each pencil is $4.

Now, using (y = 4) in the equation (4), we get,

[tex]x=[28-(3*4)]\\or,x=(28-12)\\or,x=16[/tex]i.e., Price of each notebook is $16.

Hence, the correct answer is

option(C) $16 for a notebook and $4 for a pencil.

It will take 138 minutes for the repair cost to reach $140

Although part of your question is missing, you might be referring to this full question: A repair company's charge for repairing a certain type of copy machine fits the model y = 47.38 +0.617x. Where y is the number of dollars charged and x is the number of minutes the repair person is on the job. how many minutes would it take for the cost of repair to reach $140? (round to the nearest minute.)

As per the question:

Number of dollars charged by the company = y dollars

Number of minutes the repair person is on the job = x minutes

The cost that needs to be achieved = 140 dollars

Equation:

y = 47.38 + 0.617x------(1)

For the cost of repair to reach $140, substituting $140 in y in equation (1)

140 = 47.38 + 0.617x

Solving further and finding the value of x

140 - 47.38 = 0.617x

92.62 = 0.617x

x = 138 minutes (rounded to the nearest minute)

So, it will take 138 minutes for the repair cost to reach $140
