Answer 1

Answer:

J = [12] +AJ + A = [50]

Step-by-step explanation:

If Anna's age is represented by A, then 12 more than Anna's age will be ...

  12 + A

Jason's age is said to be 12 more than Anna's age, so ...

  J = 12 + A

__

The sum of their ages will be J + A. That is said to be 50, so ...

  J + A = 50

_____

These equations can be solved by using the first to substitute for J in the second.

  (12 +A) +A = 50

  2A = 38 . . . . . . . . subtract 12

  A = 19 . . . . . . . . . . divide by 2

  J = 12 +19 = 31 . . . find Jason's age

Jason is 31; Anna is 19.

suppose that a randomly generated list of numbers from 0 to 9 is being used to simlulate an event that has a probability of success of 30% which of these groups of numbers could represent a success

Answers

Any event for which, the 3 numbers between 0 and 9 are outcomes could represent the success.

What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

Given is that suppose that a randomly generated list of numbers from 0 to 9 is being used to simulate an event that has a probability of success of 30%.

For the success rate of 30%, this means the probability of that specific event would be 0.3.

So any event for which, the 3 numbers between 0 and 9 are outcomes or are the number of favorable events could represent the success.  

Therefore, any event for which, the 3 numbers between 0 and 9 are outcomes could represent the success.

For every 15 situps Ryan does, he does 10 push-ups. Create a table of equivalent ratios that show the relationship between the number of sit-ups and the number of push-ups Ryan does.​

Answers

Answer:

15/10, 30/20, 60/40, 120/80, 240/160, 480/320

Step-by-step explanation:

The number of push-ups is 2/3 the amount of sit-ups, so the ratio of sit-ups to push-ups is 3:2.

The easy way to do this is to double both 15 and 10 so your answer will stay an equivalent ratio. You will always have a 3:2 ratio this way.

What are the more appropriate measures of center and spread for this data
set?

Answers

Except Option - A all satisfy the more appropriate measures of center and spread for the data that is median and IQR.

Given that,

We have to find what are the more appropriate measures of center and spread for data.

We know that,

Mean, median, and mode are the three central tendencies, and median is the more accurate indicator.

This is because

i) Extreme values affect the mean.

ii) If there are more outliers, the mean is in error.

iii) Means that are biassed to the right or left may not accurately reflect the nature of the data.

However, median is preferable to mean because it represents the center entry and is unaffected by extreme items or outliers.

Since extreme items will show higher standard deviation and some outliers may be misleading, IQR is a superior spread measurement tool. However, IQR provides an excellent idea.

a line has a slope of 7/10 and a y intercept of (0,-4) what is the equation of the line in standard form

Answers

Considering the definition of a line, the equation of the line in standard form is y - 7/10x= -4

What is Linear equation

A linear equation o line can be expressed in the form y = mx + b

where

x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.

The standard form of a linear equation is Ax + By = C. In this type of equation, x and y are variables and A, B, and C are integers.

Equation in this case

In this case, you know:

A line has a slope of 7/10.A line has a y-intercept of (0,-4).

So, the line can be expressed as:

y=7/10x -4

Expresed in standard form:

y - 7/10x= -4

The geometry object known as a line extends on both sides and is defined as an object with zero width. Any line without curves is said to be straight.

What is a straight line called?

An object with zero width that extends on all sides is referred to as a line in geometry. Simply put, a straight line is an uncurved line. As a result, a straight line is one without any curves that stretches to infinity on both sides.

A line is a perfectly straight, one-dimensional shape that is endlessly long and thin in both directions. A line may be referred to as a straight line or, more formally, a right line (Casey 1893), to stress that there are no "wiggles" throughout its entire length.

y=mx+c

Definition. Y=mx+c is the formula for a straight line. m is the gradient and c is the height, commonly known as the y-intercept, at where the line crosses the y-axis in the equation y = m x + c.

[tex](b) $\because$ perpendicular makes an angle of $60^{\circ}$ with the line $x+y=0$.$\therefore$ the perpendicular makes an angle of $15^{\circ}$ or $75^{\circ}$ with $x$-axis.[/tex]

[tex]Hence, the equation of line will be $x \cos 75^{\circ}+y \sin 75^{\circ}=4$or $x \cos 15^{\circ}+y \sin 15^{\circ}=4$$(\sqrt{3}-1) x+(\sqrt{3}+1) y=8 \sqrt{2}$or $\quad(\sqrt{3}+1) x+(\sqrt{3}-1) y=8 \sqrt{2}$[/tex]

Find each indicated measure.
Find m

Answers

Answer:

m<N = 32°

Arc NQ = 106°

Step-by-step explanation:

✔️Find m<N:

Inscribed angles theorem, we would have;

m<N = ½(arc MP)

arc MP = 64°

Substitute

m<N = ½(64°)

m<N = 32°

✔️Find measure of arc NQ:

m<P = ½(arc NQ) => inscribed angle theorem

53° = ½(arc NQ)

Multiply both sides by 2

2*53° = arc NQ

106° = arc NQ

Arc NQ = 106°

PLEASEEEE HELP MEE WITH THIS EQUATION

Answers

Answer:

Basically, LON would be 8z + 112 + 6z - 17

So, our equation will look like this

8z + 112 + 6z - 17 = -1z + 65

Subtract the 6z from the 8z

2z + 112 - 17 = -1z + 65

112 - 17 = 95

2z + 95 = -1z + 65

add the 1z

3z + 95 = 65

subtract the 95

-30

3z = -30

The answer is -10 :)

Step-by-step explanation:

Answer:

LON=75

Step-by-step explanation:

LON= LOM=NOM

-1z+65=8z+112-6z-17

-1z+65=2z+95

3z=-30

z=-10

LON= -1z+65

       = -1(-10)+65

       = 10+65
