Display the set of data in a histogram.

VARVARA [1.3K]

Answer:

The answer to your question is the third histogram

Step-by-step explanation:

What we must check in a histogram is that the x-axis is represented the intervals and in the y-axis is represented the frequency.

The first histogram is incorrect just by observing the first bar, we notice that the correct frequency from 0 to 4 is 3, not 14. This histogram is incorrect.

Also, the second histogram is incorrect, the frequency of the first category is 3, not 12. This histogram is wrong.

The third histogram is correct because all the bars are in agreement with their frequencies.

The last histogram is incorrect, for example, the last frequency is 12, not 3.

I dont understand this problem

Fiesta28 [93]

Answer:

D and F

Step-by-step explanation:

$x^{2}+4x+4=12$ can be rewritten as $x^{2} +4x-8=0$ .

From there you can use the quadratic formula $x=\frac{-b±\sqrt{b^{2}+4ac } }{2a}$ (ignore the A, I can‘t seem to remove it), where a=1, b=4, and c=-8.

$x=\frac{-4±\sqrt{4^{2}-4(1)(-8)} }{2(1)}$

Then you get $x=\frac{-4±\sqrt{16+32}}{2}$

Then you get $x=\frac{-4±\sqrt{48} }{2}$

So $x=-2±\frac{4\sqrt{3} }{2}$

Which means $x=-2+2\sqrt{3}$ or $-2-2\sqrt{3}$ which are choices D and F.

Malcolm is trying a very low-carbohydrate diet. He would like to keep the amount of carbs consumed in grams between the levels s

Ostrovityanka [42]

Answer:

The correct option is 2.

Step-by-step explanation:

The given inequalities are

$50$ .... (1)

$2x+10$ .... (2)

Solve each inequality.

Subtract 10 from each side of inequality (1).

$50-10$

$40$

Divide both the sides by 2.

$20$

The value of x is more than 20.

Subtract 10 from each side of inequality (2).

$2x+10-10$

$2x$

Divide both the sides by 2.

$x$

The value of x is less than 50.

Since x > 20 and x < 50, therefore Malcolm needs to consume more than 20 grams of carbohydrates, but less than 50 grams of carbohydrates.

Hence the correct option is 2.

makvit [3.9K]

Answer:

v = 2q

Step-by-step explanation:

If this is all is given in the question, then the answer is an equation. If there are numbers given, then plug the numbers into the equation to solve.
