#SPJ1

Answer:

What line is perpendicular to the line 2x + 3y = 6 through (4, 1)? Explanation: The given equation is in standard form, so it must be converted to slope-intercept form: y = mx + b to discover the slope is –2/3. To be perpendicular the new slope must be 3/2 (opposite reciprocal of the old slope).

Step-by-step explanation:

Answer: the hill

Step-by-step explanation:

It has a bigger slope angle.

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Answer:

No, because the total will be $3.62

Step-by-step explanation:

When we substitute with 3 and 2 shown below

0.35(3)+0.99(2)+0.59 we get 3.62, which is greater than 3 dollars.

Hope this helped<33

Answer:

Alright so the question states that "She can only spend $3."

A sticker costs $0.35

A eraser is $0.99

A pencil costs $0.59

What you are trying to find is Can Linda buy 3 stickers and 2 erasers.

So add the total value of stickers prices. You need to know what's the cost of 3 stickers and 2 erasers

0.35+0.35+0.35= 1.05+0.99+0.99 = 3.03 So she can't. Now can she buy 1 sticker, 1 eraser, and 1 pencil. So is it enough to get 1 of each item?

0.35+0.99+0.59=1.93 Yeah you can.

But is it enough for her to get 3 stickers, 2 erasers and a pencil?

We already know the cost for 3 stickers and 2 erasers is $3.03. All you need to do is add $0.59 to find the total cost. The total cost of 3 stickers and 2 erasers and a pencil is $3.62. So the answer is No, because the total will be $3.62 and her budget is $3 so she will need extra $0.62 to cover the full cost.

Answer:

Step-by-step explanation:

Answer:

A

w = 85

Step-by-step explanation:

To find out the number you can divided 102 by 1.2 and you get 85 meaning 85 is the answer.

Answer:

A;

Step-by-step explanation:

120% = 1.2 (decimal form)

Therefore: 1.2 x w = 102 or 102 = 1.2 x w

102 = 1.2 x w

Divide both sides by 1.2 to get:

100 = w

Multiply the numerator and denominator by the conjugate.

A conjugate is the inverse of an operation e. g + is the conjugate of -.

therefore the answer is squareroot of 10 divided by 3.

Answer:

A decimal sequence is a set of decimals that follow each other in order, and we use a rule, or pattern, to go from one number to the next. To find the rule for a sequence, we take two consecutive numbers and subtract them.

Answer:

Step-by-step explanation:

So I don't know if this will help or is the answer that you're looking for but here:

If you're multiplying a decimal by 1, it obviously stays the same.

ex: 1 x 0.25 = 0.25

If you multiply by 10 then you move the decimal place once to the right, as it gets bigger

ex: 10 x 0.25 = 2.5

you can do this for any number:

10 x 3.44 = 34.4

you can also use any power of 10.

10^2/100

100 x 2.75 = 275/275.0

Answer:

6

Step-by-step explanation:

The independent value refers to the x values of a graph. Point A is located at (6, 3). Therefore, the value of the independent variable is 6.

The value of the independent variable at point A on the graph is 6.

The cause is the independent variable. Its value is unaffected by the other study variables.

In an experimental study, an independent variable is one that you change or alter to examine its effects. It is named "independent" because it is unaffected by any other study variables.

Given:

We have two quantities from the graph one is mass in grams and another is time.

as, the masses totally depends on growth of bay with time.

So, the dependent variable is Mass and independent  variable is Time.

Now, the coordinates for Point A is (6, 3).

Hence,  the value of point A is 6.

Answer: Range and mean = 8 of both

variance of Set X= 4.7

variance of Set Y= 4.6

Step-by-step explanation:

Two sets of data, set X and set Y are given

a.) Range is the difference of the highest value and the lowest value,

Therefore, Range of set X = 12-4=8

Range of set Y = 12-4=8

Now, Mean of a given data set is the average of all the terms present in the given data set

Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8

Mean of set Y= (4+5+7+32+20+12)/10= 8

Therefore, both the data sets has same range and mean.

b.) Standard deviation tells about the variability of the date and is given by,

S.D= σ = √∑ ( X − μ )^2/n

S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7

S.D of set Y= √(16+9+1+0+4+16)/10= √4.6

Variance is the square of S.D, that is, σ^2

Therefore, variance of set X=4.6

variance of set Y= 4.7

c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Step-by-step explanation:

Answer:

y= 3x+125

Step-by-step explanation:

y intercept is 125

gradient is 3

y=Mx+c

y=3x+125

Answer:

y = 75x + 125

Step-by-step explanation:

Write in form y = mx + b

75 is the slope (m)

125 is the y-intercept (b)

So the equation would be y = 75x + 125.

BTW, the slope is written in rise/run form. For this graph, it is 75/1.
