3×(3+12÷3)−4 Can someone please answer this?

Answer:

Step-by-step explanation:

To make a histogram, follow these steps:

What does a histogram mean?

Histograms are equivalent to bar charts; they are a means for data counts to be displayed. Real counts against categories are seen in a bar graph; the bar height represents the number of objects in that category. In "bins", a histogram reveals the same categorical variables.

Create a Histogram: Stages for Steps

Sample question: With the following test scores, construct a histogram: 99, 97, 94, 88, 84, 81, 80, 77, 71, 25.

Phase 1: Diagram the x and y axes and label them. The x-axis would be labelled "score" for this case, and the y-axis would be labelled "relative percentage of frequency ."

Phase 2: Pick the number of bins (in statistics, how to choose bin sizes) and mark your graph. Query, Grou, Grou, for this sample,It's a smart option for groups of 10 (the x-axis values are the bins) (it looks like you'll have 5 bars of one or two objects in the group).

Step 3: To get an indication of where to put the frequency "ticks," divide 100 by the number of data points. In our data collection, we have 10 objects, so it makes sense to count 100/10 = 10 percent (one item would equal 10 percent of the total).

Build a histogram

Step 4: Count how many objects are in each bin and then outline a rectangle corresponding to the percentage of the total filled by the bin on the graph. The first bin (20-30) has 1 object in this sample data package, with 70-80 getting two items. When an object lands on a bin boundary (i.e. 80), bring it up in the next bin (80 will go to 80-90)

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

We see that the line intersects the y-axis at -1.  As a result, we need to choose an equation with -1, either B or C.  We see that the different is the slope.  For choice B, the slope is [tex]\frac{1}{3}[/tex], meaning that every unit up equates to 3 blocks to the right.  Counting along the line, we see that this is correct.

Answer:

11943.31 mg

Step-by-step explanation:

460mg a day per kilo of weight, 4 doses for that total amount

460/4=115mg per kilo per dose

1 kilo = 2.205 pounds

115/2.205=52.15 approx mg per pound per dose

52.15*229=11943.31 approx, which is how much per dose

Given:

The function is

[tex]f(x)=x^3-2[/tex]

The secant line passing through (-4,f(-4)) and (2,f(2)).

To find:

The equation of the secant line.

Solution:

We have,

[tex]f(x)=x^3-2[/tex]

At x=-4,

[tex]f(-4)=(-4)^3-2[/tex]

[tex]f(-4)=-64-2[/tex]

[tex]f(-4)=-66[/tex]

At x=2,

[tex]f(2)=(2)^3-2[/tex]

[tex]f(2)=8-2[/tex]

[tex]f(2)=6[/tex]

The secant line passes through the points (-4,-66) and (2,6). So, the equation of the secant line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-(-66)=\dfrac{6-(-66)}{2-(-4)}(x-(-4))[/tex]

[tex]y+66=\dfrac{6+66}{2+4}(x+4)[/tex]

[tex]y+66=\dfrac{72}{6}(x+4)[/tex]

On further simplification, we get

[tex]y+66=12(x+4)[/tex]

[tex]y+66=12x+48[/tex]

[tex]y=12x+48-66[/tex]

[tex]y=12x-18[/tex]

Therefor, the equation of the secant line is [tex]y=12x-18[/tex].

Answer:

[tex]x=131.25[/tex]

Step-by-step explanation:

[tex]0.3x+0.65*175=0.5(x+175)[/tex]

[tex]0.3x+113.75=0.5x+87.5[/tex] (Simplify both sides of the equation by multiplying on the LHS and distributing on the RHS)

[tex]0.3x+113.75-0.5x=0.5x+87.5-0.5x[/tex] (Subtract [tex]0.5x[/tex] from both sides of the equation to get all [tex]x[/tex] terms to one side)

[tex]-0.2x+113.75=87.5[/tex] (Simplify)

[tex]-0.2x+113.75-113.75=87.5-113.75[/tex] (Subtract [tex]113.75[/tex] from both sides of the equation to isolate [tex]x[/tex])

[tex]-0.2x=-26.25[/tex] (Simplify)

[tex]\frac{-0.2x}{-0.2} =\frac{-26.25}{-0.2}[/tex] (Divide both sides of the equation by [tex]-0.2[/tex] to get rid of [tex]x[/tex]'s coefficient)

[tex]x=131.25[/tex] (Simplify)

Answer:

( 1.5 , 3.5 )

Step-by-step explanation:

Answer:

(3/2, 7/2)

Step-by-step explanation:

We find the mean (average) of 4 and -1, obtaining 3/2 by combining 4 and -1 and then dividing the result by 2.  Thus, the x-coordinate of the midpoint is xm = 3/2.

Similarly, we find the mean of 1 and 6, obtaining ym = 7/2.

Thus, the midpoint is (3/2, 7/2).

2.4 x 1/3 = 0.8 liters more.

2.4 + 0.8 = 3.2 liters

Answer: 2.2876792e+13

Step-by-step explanation: calculator

Step-by-step explanation:

Two functions are defined by these equations:

f(x) = 5.1 + 0.8x

g(x) = 3.4 + 1.2x

Put x = 3.9 in both f(x) and g(x).

f(x) = 5.1 + 0.8(3.9)

= 8.22

g(x) = 3.4 + 1.2(3.9)

= 8.08

So, f(x) is greater than g(x).

f(x)-g(x) = 8.22 - 8.08

= 0.14

So, f(x) is 0.14 units more than g(x).

Answer:

$241,400

Step-by-step explanation:

House costs: $200,000

Percentage increase: 20.7%

This means that the cost of the house increased by that percentage from 2012 to 2013. Therefore the following,

200,000 x 20.7/100 = 41,400

So the value of the house increased by $41,400 in this year.

Now we add to evaluate the total price of the house in 2013.

200,000 + 41,400 = 241,400

House price: $241,400

Answer:

120

Step-by-step explanation:

We know that 36 is 30% of total items

So our equation would be 36/? = 30/100

From there we cross multiply so 36x100 = 3600

From there, we divide 3600 by 100

Therefore, your answer is 120

Answer:

30 yellow beads

Step-by-step explanation:

there is a difference of three beads if there are 5 yellow beads per 2 red beads. You're looking for a combination of numbers with a difference of 18. divide 18 by three, and you get 6. multiply 6 by each of the 2 numbers 2 and 5, to get 12 and 30. They have a difference of 18, and follow the ratio of red to yellow beads. Now just take the 30 yellow beads and give an answer

That is your triangle.

Now, since its a right triangle, we can use the Pythagorean theorem to solve for x.

The equation for the Pythagorean theorem is this: [tex]A^{2} + B^{2} = C^{2}[/tex]

So we plug in the values.

[tex](x^{2} ) + (x-9)^{2} = (x + 9)^{2}[/tex]

We solve for x.

[tex]x^{2} + x^{2} -18x + 81 = x^{2} + 18x + 81[/tex]

Get everything to the left side of the equation. (x^2 + x^2 = 2x^2, - x^2 = x^2;

-18x - 18x = -36x;    81 - 81 = 0)

[tex]x^{2} -36x = 0[/tex]

Add 36x to both sides, then divide by x.

[tex]x^{2} = 36x\\\\x = 36[/tex]
