Answer:

The third one, y = 5 x 10

Step-by-step explanation:

y = number of Kate's pens, 5 = how many times more pens Kate has than Mark, and 10 = how many pens Mark has.

Answer:

D, 34.8 + b =54.6

[tex]perimeter = s + s + s \\ 54.6 = 3a + a + b \\ 54.6 = 4a + b \\ (4 \times 8.7) + b = 54.6 \\ 34.8 + b = 54.6[/tex]

The equation is

y = $ 12.35 x

Step-by-step explanation:

Cost of one bag of rocks = $ 12.35

Let there are x bags of rocks, so that the total cost is y.

So, the cost of 1 bag = $ 12.35

cost of x bags = $12.35 x

The total cost is

y = $12.35 x

It is the equation of a straight line which passes from origin and the slope is 12.35.

Aan angle in quadrant I, the value of sin[tex]\theta[/tex] is [tex]\rm Sin \theta=\dfrac{\sqrt{14} }{5}[/tex].

Sin theta is defined as the ratio of perpendicular and hypotenuse.

The given equation is;

[tex]\rm Cos\theta=\dfrac{\sqrt{11} }{5}[/tex]

The cos[tex]\theta[/tex] is given by;

[tex]\rm Cos\theta=\dfrac{Base}{hypotenuse}[/tex]

By applying Pythagoras theorem the value of base is;

[tex]\rm (5)^2=Perpendicular^2+ (\sqrt{11} )^2\\\\ Perpendicular^2= 25-11\\\\ Perpendicular^2=14\\\\ Perpendicular =\sqrt{14}[/tex]

The value of sin[tex]\theta[/tex] is;

[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypoteunse}\\\\Sin \theta=\dfrac{\sqrt{14} }{5}[/tex]

Hence, the value of sin[tex]\theta[/tex] is [tex]\rm Sin \theta=\dfrac{\sqrt{14} }{5}[/tex].

So, the function that represents the total amount of money Jodi has can be modeled by

45 cups can wash 180 times

Answer:

1) you're going to have to flip the coins (or fake numbers) for the experimental trials.

2) for the theoretical, there is 1/2 chance for heads or tails with each toss, so you'd expect that out of 10 tosses, 5 heads, 5 tails. out of 100 tosses- 50 heads, 50 tails.

When tossing 2 coins- 1/2×1/2 = 1/4 (25%) chance that 2 heads, 2 tails, or 1 heads & 1 tails. Deviation value comes from after you done your flipping and recorded your data. So if on 100 flips you actually got 50 and 50 (rarely us that exact ;), the deviation from the expected of 50/50 would be 0.00. If however you flipped 100 heads or 100 tails (impossible), then the deviation value would be 1.00.

|(100-50)| ÷ 50 = 50÷50 = 1.00

So usually you may have data like: 47/53 or something a little off than 50/50, making deviation |(47-50)| ÷ 50 = 3÷50 = 0.06.

Now the number of flips is important for the outcome! So if a coin toss if 10 times had 4 heads, 6 tails, the deviation value would be:

|(4-5)| ÷ 5 = 1÷5 = 0.20

So increasing the # flips DECREASES the deviation value!!

Whether it's from 10 to 100, or from 100 to 200. Look at my example of how the 10-flip deviation of 0.20 decreased to 0.06 with 100-flip

Answer:

C: f(x) = -½x + 4

Step-by-step explanation:

Using slope formula between 2 points, we know that;

slope; m = (y2 - y1)/(x2 - x1)

Let's consider 2 points from the table;

(0, 4) and (-4, 6)

Thus;

m = (6 - 4)/(-4 - 0)

m = 2/-4

m = -½

Now using slope intercept form equation which is y - y1 = m(x - x1), we can find the equation of the function by picking on point say (0, 4).

Thus;

y - 4 = -½(x - 0)

y - 4 = -½x

y = -½x + 4

Thus;

f(x) = -½x + 4

Step-by-step explanation:

x-intercept => point (2, 0)

y-intercept => point (0, -4)

Answer:

(0,3)

Step-by-step explanation:

solve for 2y

-X-2y= -6

2y=6+2x

substitute the given value of 2y into the equation -x-2y=-6

-x-(6+3x)= -6

solve for x

x=0

substitute the given value of X into the equation 2y=6+3x

2y=6+3×0

solve for y

y=3

the solution is (0,3)

The question is incomplete, as the functions are not given.

The general explanation on calculating average rate of change is as follows.

The average rate of change (m) of function f(x) over interval (a,b) is:

[tex]m = \frac{f(b) - f(a)}{b-a}[/tex]

Take for instance:

[tex]f(x) = x^2 + 4x + 4[/tex]

[tex](a,b) = (0,2)[/tex]

The average rate of change over [tex](0,2)[/tex] is:

[tex]m = \frac{f(2) - f(0)}{2-0}[/tex]

[tex]m = \frac{f(2) - f(0)}{2}[/tex]

Calculate f(2) and f(0)

[tex]f(2) = 2^2 + 4*2 + 4 =16[/tex]

[tex]f(0) = 0^2 + 4*0 + 4 =4[/tex]

So, we have:

[tex]m = \frac{f(2) - f(0)}{2}[/tex]

[tex]m = \frac{16 - 4}{2}[/tex]

[tex]m = \frac{12}{2}[/tex]

[tex]m = 8[/tex]

Step-by-step explanation:

A safety committee randomly examined 900 construction workers during their work, and found that 48 workers were not wearing helmets. Estimate the percentage of workers who do not wear protective masks during their working time with 98% confidence

total workers = 900

Not wearing helmet = 48

Percentage which are not wearing the helmets

Answer:

Option A

Step-by-step explanation:

ok so firstly this is super duper easy! all you have to see first in these type of questions is the "sequence" or the "pattern". and you have to make a ittle equation with this, so the first picture has 1 square, secound one has 5, the third one has 9, and the fourth one has 13.

- so firstly see or find a specific sequence.

13 - 9 = 4

9 - 5 = 4

5 - 1 = 4

so we found out "4" is the main changing unit. Now lets make a short formula which will help us determine any number ahead of the picture.

so lets do 4x = number of squares, x= figure number

4(1) = 4 :: wrong, because the first figure has only one square

so, 4x - 3

4(1) - 3 = 1 :: correct! this euqation works!

Now, we need to find how many squared there are in figure 100, so ->

4(100) - 3 = 397 squares!

and now doing the question will be easier, because option A says 1 square in the centre and 99 sqaures on each side.

So-> 99 + 99 + 99 + 99 +1 = 397! boom!! got the answer!

Answer:

f-g)(x)= | 7x + 1 | -6 Is correct

Step-by-step explanation:

Functions f(x) and g(x) are illustrations of composite functions.

The value of (f - g)(x) is |7x + 1| - 6

The functions are given as:

[tex]\mathbf{f(x) = |7x +1|- 8}[/tex]

[tex]\mathbf{g(x) = -2}[/tex]

The function (f - g)(x) is calculated using:

[tex]\mathbf{(f - g)(x) = f(x) - g(x)}[/tex]

So, we have:

[tex]\mathbf{(f - g)(x) = |7x + 1| - 8 - (-2)}[/tex]

Remove bracket

[tex]\mathbf{(f - g)(x) = |7x + 1| - 8 +2}[/tex]

Simplify

[tex]\mathbf{(f - g)(x) = |7x + 1| - 6}[/tex]

Hence, the value of (f - g)(x) is |7x + 1| - 6
