Answer:

B

Step-by-step explanation:

We know 2.2 pounds = 1 kg, hence,

44 pounds / 2.2 = 20 kg (weight of child in kg)

Now, since 40 mg is administered per kg, the child would need 40 * 20 = 800 mg PER DAY

Since this is going to be taken per 4 dose, each dose would need to be 800/4 = 200 mg

Answer choice B is right.

For this case we must simplify the following expression:

[tex](x ^ {\frac {3} {2}}) ^ 6[/tex]

We have that by definition of properties of powers that is fulfilled:

[tex](a ^ n) ^ m = a ^ {n * m}[/tex]

Then, rewriting the expression:

[tex]x ^ {\frac {3 * 6} {2}} =\\x ^ {\frac {18} {2}} =\\x ^ 9[/tex]

Answer:

[tex](x^{\frac{3}{2}})^6=x^9[/tex]

Final answer:

To simplify the expression [tex](x^{3/2)6[/tex], use the power rule of exponents to get x to the power of 9, which is the simplified form of the expression.

Explanation:

To simplify the expression [tex](x^{3/2)6[/tex], we need to apply the power of a power property, which states that when you raise a power to another power, you multiply the exponents.

So, we have:

[tex](x^{3/2)6[/tex] = [tex]x^{(3/2)\times 6[/tex]

= [tex]x^{3\times 3[/tex]

= x⁹

Therefore, [tex](x^{3/2)6[/tex] simplifies to x⁹.

This means that the expression is equivalent to x raised to the power of 9.

In summary, when you raise x to the power of 3/2 and then raise that result to the power of 6, you end up with x raised to the power of 9.

Answer:

Step-by-step explanation:

In this problem we have independent events, that is, the event "picking a girl" doesn't affect an "picking a boy", also, picking picking a girl doesn't affect the probability of the other subjects.

So, the probability when the first girl is being picked is:

[tex]P_{1}=\frac{7 \ girls}{9 \ students}[/tex]

Because among the total 9 students, there are 7 girls.

Now, after picking one girl, there remains 6 girls and 8 students to be picked. So, the probability of the second girl would be:

[tex]P_{2}=\frac{6 \ girls}{8 \ students}[/tex]

Then, the probability of the third girl:

[tex]P_{3}=\frac{5 \ girls}{7 \ students}[/tex]

The fourth girl probability:

[tex]P_{3}=\frac{4 \ girls}{6 \ students}[/tex]

Therefore, the probability of picking all 4 girls would be the product of each probability, because events are independent (we use product when they are independent):

[tex]P=\frac{7 \ girls}{9 \ students} \times \frac{6 \ girls}{8 \ students} \times \frac{5 \ girls}{7 \ students} \times \frac{4 \ girls}{6 \ students}\\P=\frac{5}{18}=0.28 \ (or \  28\%)[/tex]

Therefore, there's 28% probability that every student in the group is a girl.

The probability that everyone in the group is a girl is 0.2778

The distribution of the students is given as:

Boys = 2

Girls = 7

Total = 9

The selection of the 4 girls at random is:

So, the probability that all students are girls is:

P = 7/9 * 6/8 * 5/7 * 4/6

Evaluate

P = 0.2778

Hence, the probability that everyone in the group is a girl is 0.2778

Make two equations representing the position of each animal, p and k, for the puppy and kitten respectively.

p=25t and k=180+20t  

The puppy will catch the kitten when p=k so we can say:

25t=180+20t  subtract 20t from both sides

5t=180  divide both sides by 5

t=36

So the puppy will catch the kitten after 36 seconds.

Step-by-step explanation:

let the points of G be (a,b)

mid point of GH =(-6,-3)

point of H =(-4,4)

now,

for x coordinate,

-6=(a-4)/2

or, a-4 =-12

or, a=-8

for y coordinate,

-3=(b+4)/2

or, -6=b+4

or, b=-10

therefore, the coordinate of G is (-8,-10)

To solve the question, we use the midpoint formula, which is derived from the concept of averages. Given the midpoint and one endpoint, we can find the other endpoint by setting up and solving simple equations. The coordinates of the other endpoint are G(-4, -14).

To find the coordinates of the other endpoint of a line segment given the coordinates of the midpoint and one endpoint, we use the midpoint formula which states that the midpoint, M, of a line segment GH is given by M = [(x1 + x2)/2 , (y1 + y2)/2], where (x1,y1) and (x2,y2) are the coordinates of H and G respectively.

Given that M (-6,-3) and H (-4,4), we can write the equations: -6 = [(-4 + x2)/2] and -3 = [(4 + y2)/2]

Solving these equations gives us: x2 = -2*(-6 + 4) = -4 and y2 = -2*(-3 - 4) = -14. Therefore, the coordinates of endpoint G are G (-4, -14).

Answer:  1st, 3rd  and 5th answers are correct

Step-by-step explanation:

Answer:

A) The theoretical probability of spinning any one of the five colors is 20%.

C) The theoretical probability of spinning green is equal to the experimental probability of spinning green.

E) If Yuri spins the spinner 600 more times and records results, the experimental probability of spinning orange will get closer to the theoretical probability of spinning orange.

Step-by-step explanation:

Let's find the probability of each events.

Probability of a event = The number of favorable outcomes / The total number of possible outcomes.

Here the total number of possible outcomes = 10.

Probability of getting blue = 1/10 = 0.10

Probability of getting green = 2/10 = 1/5= 0.20 = 20%

Probability of getting red = 0/10 = 0

Probability of getting orange = 4/10 = 0.40

Probability of getting yellow = 3/10 = 0.30

The above are the experimental probability.

The theoretical probability of getting green = 1/5 = 0.20 = 20%

By looking at the results, the following statements are true.

A) The theoretical probability of spinning any one of the five colors is 20%.

C) The theoretical probability of spinning green is equal to the experimental probability of spinning green.

E) If Yuri spins the spinner 600 more times and records results, the experimental probability of spinning orange will get closer to the theoretical probability of spinning orange.

Answer:

Step-by-step explanation:

A quadratic equation is an expression that has an x^2 term. Quadratic equations are most commonly expressed as ax^2+bx+c, where a, b and c are coefficients. Coefficients are numerical values. For example, in the expression 2x^2+3x-5, 2 is the coefficient of the x^2 term. Once you have identified the coefficients, you can use a formula to find the x-coordinate and the y-coordinate for the minimum or maximum value of the quadratic equation.

Determine whether the function will have a minimum or a maximum depending on the coefficient of the x^2 term. If the x^2 coefficient is positive, the function has a minimum. If it is negative, the function has a maximum. For example, if you have the function 2x^2+3x-5, the function has a minimum because the x^2 coefficient, 2, is positive.

Divide the coefficient of the x term by twice the coefficient of the x^2 term. In 2x^2+3x-5, you would divide 3, the x coefficient, by 4, twice the x^2 coefficient, to get 0.75.Multiply the Step 2 result by -1 to find the x-coordinate of the minimum or maximum. In 2x^2+3x-5, you would multiply 0.75 by -1 to get -0.75 as the x-coordinate.

Plug in the x-coordinate into the expression to find the y-coordinate of the minimum or maximum. You would plug -0.75 into 2x^2+3x-5 to get 2_(-0.75)^2+3_-0.75-5, which simplifies to -6.125. This means the minimum of this equation would be x=-0.75 and y=-6.125.

If there is not a number before a variable, the coefficient is 1. For example, if your expression is x^2+5x+1, the x^2 coefficient is 1.

Answer:

c = 14

Step-by-step explanation:

For this triangle we have to

[tex]a=18.2\\B=62\°\\C=48\°[/tex]

We want to find the length of b

We know that the sum of the internal angles of a triangle is 180 °

then

[tex]A + 62 +48=180\\\\A=180-62-48\\\\A=70\°[/tex]

Now we use the sine theorem to find the length of c:

[tex]\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}[/tex]

Therefore:

[tex]\frac{sin(A)}{a}=\frac{sin(C)}{c}\\\\c=\frac{sin(C)}{\frac{sin(A)}{a}}\\\\c=a*\frac{sin(C)}{sin(A)}\\\\c=(18.2)\frac{sin(48)}{sin(70)}\\\\c=14[/tex]

Answer:

c= 14

Step-by-step explanation:

First, let's find the angle A, because it's easy and because we'll need it.

We know that the sum of the interior angles of a triangle is 180, and we have 2 angles... so we can easily find A:

A = 180 - 62 - 48 = 70 degrees

Now, we can use the law of Sines to find c:

[tex]\frac{c}{sin(C)} = \frac{a}{sin(A)}[/tex]

so...

[tex]c = \frac{a * sin(C)}{sin(A)} = \frac{18.2 * sin(48)}{sin(70)} = 14.39[/tex]

The precise answer is 14.39, but you are asked to round up to the closest whole number... so 14.

Answer: 3 1/4 as an improper fraction could be 13/4. Written as a fraction would be 3 1/4.

Answer:

At the beginning

16 men and 24 women

In the end

16 men and 20 women

Step-by-step explanation:

Call x the number of men on the bus and call y the number of women on the bus.

We know that the initial ratio between men and women is 2: 3

And the final ratio is 4: 5

So

[tex]\frac{x}{y}=\frac{2}{3}\\\\y = \frac{3}{2}x[/tex]   (1)

After the 4 women are down, the proportion is:

[tex]\frac{x}{y-4}=\frac{4}{5}\\\\y-4 = \frac{5}{4}x\\\\y= \frac{5}{4}x +4[/tex]   (2)

Substitute the value of y in the first equation and solve for x

[tex]\frac{5}{4}x +4=\frac{3}{2}x\\\\-\frac{1}{4}x=-4\\\\x=16\ men[/tex]

Now solve for y.

[tex]y = \frac{3}{2}(16)\\\\y=24\ women[/tex]

We plug in the vertex to obtain:

[tex]f(x)=a(x-7)^2-3[/tex].

Since the graph passes through (5,5) and (9,5), they must satisfy its equation.

[tex]5=a(9-7)^2-3[/tex].

[tex]5+3=4a[/tex].

[tex]8=4a[/tex]

Divide both sides by 4.

Answer:

162.24 ft

Step-by-step explanation:

So you first find the area of one side.

5.2 x 5.2 = 27.4

Then you times it by 6, because a cube has 6 sides.

27.4 x 6 = 162.24 ft

A steel cargo container is shaped like a cube measuring 5.2 ft on each edge. we will need 162.24 ft sq. steel to make this container.

A cube has all sides congruent, so all sides have the same area.

Supposing that the considered cube has a side length (also called edge length) of L units.

Then, its one side's area equals  L^2 sq. units (as each side is a square, so we used the formula for the area of a square).

Since there are 6 such sides in a closed cube, thus, its surface area evaluates to

[tex]S = L^2 + L^2 + ... + L^2 \text{\: (six times)} = 6L^2 \: \rm unit^2[/tex]

A steel cargo container is shaped like a cube measuring 5.2 ft on each edge.

So first we need to find the area of one side.

The area of a square = 5.2 x 5.2

                                   = 27.4
