State whether the given point is a solution to the system of equations.

Answers

Answer: What is the best way to determine whether a given point is a solution to a system of equations? If you are asked if a point is a solution to an equation, we replace the variables with the given values and see if the 2 sides of the equation are equal (so is a solution), or not equal (so not a solution). ... So, we test the point in both equations.  Where is the solution of a system of equations? The solution to a system of linear equations is the point which lies on both lines. In other words, the solution is the point where the two lines intersect

Tyrone ran the 100-meter race 3 times. His fastest time was 10.84 seconds. His slowest time was 13.52 seconds. If Tyrone's average time was 12.0 seconds, what was his time for the third race? *​

Answers

Answer:

The third time = 11.64 seconds

Step-by-step explanation:

Let the average time be x

The average of a set of numbers is the sum of the numbers divided by the number of terms. In this case:

Average = (10.84 + 13.52 + x) ÷ 3 = 12.0

[tex]\frac{10.84\ + 13.52\ + x}{3}= 12.0\\\frac{24.36\ +\ x}{3} = 12.0\\cross-multiplying\\24.36\ +\ x = 3 \times 12.0\\24.36\ +\ x = 36\\x = 36 - 24.36\\x = 11.64\ seconds[/tex]

5. Evaluate f(x) = 2x – 7 at the given value. f(4)=?

Answers

Answer:

f(5) = 14

Step-by-step explanation:

Just replace the variable "x" with "5":

f(5) = 2×5 + 4 = 14

Answer:

1

Step-by-step explanation:

Since the value of x is 4 ( because four is in the position of x) you would plug in 4 into he equation.

2(4) = 8

Then 8 - 7 = 1

F(4) is 1

Therefore, your final answer is 1.

Step-by-step explanation:

Let's solve your equation step-by-step.

9+4b=17

Step 1: Simplify both sides of the equation.

4b+9=17

Step 2: Subtract 9 from both sides.

4b+9−9=17−9

4b=8

A fair 10 sided die rolled until a 7 is first seen. What is the probability of rolling the die six times?

Answers

Answer:

The probability of rolling a dice six time until a 7 is first seen is 0.059

Step-by-step explanation:

The probability of getting a seven is equal to [tex]\frac{1}{10}[/tex]

The dice need to be rolled only six times.

This means that for the first 5 times the dice showed values other than 7 and in the last roll it displays 7

Hence the probability of rolling a dice six time until a 7 is first seen is

[tex](\frac{9}{10})^5 * (\frac{1}{10})^1[/tex]

[tex]= \frac{9^5}{10^6} \\= 5.90[/tex] % or 0.059

What is the sixth number in the Fibonacci sequence with the first two numbers 1 and 4?

Answers

Answer:

23

Step-by-step explanation:

1 + 4 = 5 so we get 1 4 5

then 4+5 = 9, 1 4 5 9

5+9 = 14, 1 4 5 9 14

9+14 = 23, so

1 4 5 9 14 23

23 is the 6th number in this sequence

The sixth number in the Fibonacci sequence with the first two numbers 1 and 4 is 23 and this can be determined by using the arithmetic operations.

Given :

Fibonacci sequence with the first two numbers 1 and 4.

The following steps can be used to determine the sixth number in the Fibonacci sequence:

Step 1 - If the first two numbers in the Fibonacci sequence is 1 and 4 then the third number is:

= 1 + 4

= 5

Step 2 - The Fourth number in the Fibonacci sequence is:

= 4 + 5

= 9

Step 3 - The Fifth number in the Fibonacci sequence is:

= 5 + 9

= 14

Step 4 - The Sixth number in the Fibonacci sequence is:

= 9 + 14

= 23

So, the sixth number in the Fibonacci sequence with the first two numbers 1 and 4 is 23.

FIND BC
round to the nearest HUNDREDTH ​

Answers

Answer:

CB = 30.15

Step-by-step explanation:

180-58-93 = 29 degrees for angle B

draw a line perpendicular to BC down to point A, lets call the perpendicular point D.

now you've got 2 similar, smaller triangles

angle A is split into two angles, 29 degrees above and 58 degrees below.

sin 29 =CD/16

CD = 7.75

cos 29 = AD/16

AD = 14

tan 58 =DB/AD = DB/14
