Answer:

X= 32 Y= 35

Step-by-step explanation:

We know FOB is parralel to AOE meaning x= 32

also, COH = 90 so GOD is also 90.

a straight angle is 180, so

23+90+x or 32= 145,

180-145=35,

y=35

Answer:

X=32

Y=35

Step-by-step explanation:

We know x is 32 because FOB is parrallel to AOE.

We also know that DOG is 90 because COH is 90, and parallel to DOG

So, we can do:

90 + 23 + 32 =145

180-145=35, which is Y

A graph has a constant of proportionality of 7.2. Let y represent minutes and x represent miles.

vodka [1.7K]

Answer:

7.2 minutes per mile

Step-by-step explanation:

If we assume the description means y = 7.2x, the rate 7.2 means each increase in x of 1 mile results in an increase in y of 7.2 minutes. That is the rate is 7.2 minutes per mile.

Given f(x) = 3x + 1, solve for x when f(x) = 7.

irakobra [83]

Answer:

f(7) = 22 or x =2

Step-by-step explanation:

f(x) = 3x + 1
f(7) = 3(7) + 1
f(7) = 21 + 1
f(7) = 22

Or if the equation meant it like this:

f(x) = 3x + 1
7 = 3x + 1
6 = 3x
2 = x

Please help i d k if its -128 or -1/128

7nadin3 [17]

Answer:

$\frac{ {y}^{ - 5} }{x {}^{ - 3} } \\$

when x is 2, y is -4

$= \frac{ {( - 4)}^{5} }{ {2}^{ - 3} } \\ \\ = - 1024 \times {2}^{3} \\ = - 1024 \times 8 \\ = - 8192$

In a certain pond, 50 fish were caught, tagged, and returned to the pond. A few days later, 50 fish were caught again, of which

mario62 [17]

2 out of 50 were tagged.

Divide 2 by 50:

2/50 = 0.4 ( This is 4% of the fish were tagged).

Now divide the number of fish caught by the percentage that were tagged:

50 / 0.04 = 1250

The number of fish in the pond is C. 1250

This is used for the next few questions: The rating for the new scary movie has a scale of 0 to 10. The average response was tha

Pie

Answer:

The percentage that of people who gave the movie a rating between 6.8 and 8.8

P(6.8≤X≤8.8) = 83.9≅ 84 percentage

Step-by-step explanation:

Step(i):-

Mean of the Population = 8.3 points

Standard deviation of the Population = 0.5 points

Let 'X' be the random variable in normal distribution

Let X = 6.8

$Z = \frac{x-mean}{S.D} = \frac{6.8-8.3}{0.5} = -3$

Let X = 8.8

$Z = \frac{x-mean}{S.D} = \frac{8.8-8.3}{0.5} = 1$

The probability that of people who gave the movie a rating between 6.8 and 8.8

P(6.8≤X≤8.8) = P(-3≤Z≤1)

= P(Z≤1)- P(Z≤-3)

= 0.5 + A(1) - ( 0.5 -A(-3))

= A(1) + A(3) (∵A(-3)=A(3)

= 0.3413 +0.4986 (∵ From Normal table)

= 0.8399

Conclusion:-

The percentage that of people who gave the movie a rating between 6.8 and 8.8

P(6.8≤X≤8.8) = 83.9≅ 84 percentage
