Answer:

3 tablets

Step-by-step explanation:

Since the drug is to be administered in 20.75 mg tablets, we divide 62.25 by 20.75 to get the number of tablets required.

62.25 ➗ 20.75 = 3

3 tablets are to be administered

Answer:

Step-by-step explanation:

Given that:

The sample size = 150

The sample mean = 70.69

The standard deviation = 29.60

The sample mean is equal  to the point estimate of the population = 70.69

At 99% confidence interval level is:

∝ = 1 - 0.99

∝ = 0.01

The critical value:

[tex]Z_{\alpha/2} = Z_{0.01/2} \\ \\ Z_{0.005} = 2.58 \ using \ Z \ tables[/tex]

The Margin of error = [tex]Z_{\alpha/2} \times \dfrac{\sigma}{\sqrt{n}}[/tex]

[tex]= 2.58 \times \dfrac{29.6}{\sqrt{150}}[/tex]

= 2.58 × 2.4168

≅ 6.235

At 99% confidence interval; the estimate of the population mean lies within the interval:

= [tex]\overline x - E < \mu \ < \overline x + E[/tex]

= 70.69 - 6.235 < μ <  70.69 + 6.235

= 64.455  < μ < 76.925

= (64.455 , 76.925 )

Answer:2

Step-by-step explanation:

5 divided by2.5=2

7 divided by 3.5=2 which makes your scale factor 2

The scale factor of the given dilation is required.

The scale factor of dilation is [tex]2[/tex].

The original dimensions are [tex]2.5"[/tex] by [tex]3.5"[/tex]

The final dimensions are [tex]5"[/tex] by [tex]7"[/tex]

Scale factor is given by

[tex]\dfrac{\text{Final dimension}}{\text{Initial dimension}}[/tex]

[tex]\dfrac{5}{2.5}=2[/tex]

[tex]\dfrac{7}{3.5}=2[/tex]

The scale factor of dilation is [tex]2[/tex].

Answer: The cost is $600

Step-by-step explanation: The wall is a rectangle whose area is calculated as:

S = 8.5 x 2

S = 17

However, there is a door on the wall which won't be whitewashed so:

Area of door:

[tex]S_{d}[/tex] = 2 x 1

[tex]S_{d}[/tex] = 2

Whitewashed area will be

S - [tex]S_{d}[/tex] = 17 - 2

S - [tex]S_{d}[/tex] = 15m²

To whitewash the wall, it costs $40 per each m², so:

Cost = 15*40

Cost = 600

To whitewash the wall, it will cost $600.

The answer is 140%

1.4 x 100 = 140%

Step-by-step explanation:

The horizontal midpoint of the page is;

The horizontal midpoint of the image is given as;

For the image to be centered, these to midpoints must be on the same point in the axis.

If we take the leftmost edge of the paper to be point zero on the axis, then, the distance accommodated by the paper is 10.795cm.  The distance that goes beyond this leftmost edge is computed as;

On the axis, this is on the negative side. Therefore, the horizontal position for the left edge of the image that Joelle should use to center the image is -4.46cm.

Answer:

I disagree

'No it won;t

Step-by-step explanation:

Given the inequality functions;

-2(3 – x) > 2x – 6

Open the parenthesis

-2(3) -2(-x)  > 2x - 6

-6 + 2x > 2x - 6

Collect like terms

2x-2x > -6 + 6

0x > 0

x > 0/0

The value of x does not exist on any real number. I disagree with my friend since the value of x is an indeterminate function. If the inequality were ≥, it won't change anything as the value of x won't still exist on any real number

Correct question is;

A manufacturer determines that the number of drills it can sell is given by the formula,D = -4p2 + 160p – 305 where p is the price of the drills in dollars.

A) At what price will the manufacturer sell the maximum number of drills?

B) What is the maximum number if drills that can be sold?

Answer:

A) $20

B) D_max = 1295 drills

Step-by-step explanation:

We are given that the price for number of drills it can sell is given by the formula, D = -4p² + 160p – 305 where p is the price of the drills in dollars.

A) To find the price for selling maximum number of drills, we will find the derivative of the function D and equate to zero.

D' = -8p + 160

Equating to zero gives;

-8p + 160 = 0

8p = 160

p = 160/8

p = $20

B) maximum number of drills will occur at p = $20.

Thus;

D_max = -4(20)² + 160(20) – 305

D_max = -1600 + 3200 - 305

D_max = 1295
