HELO ASAP ILL GIVE BRAINLIST

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:

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

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: 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.

Answer: This is five points

Step-by-step explanation:

Assuming that Clarence repaired the eight transmissions using 2 days, he will likely repair 24 transmissions if he works for the next 6 days.

A proportion shows the relationship between two or more ratios or quantities.

Number of transmissions repaired in 2 days = 8

Number of days to repair more transmissions = 6

Estimated number of transmissions to be repaired = 24 (8/2 x 6)

Since the graph was not showed, it is assumed that Clarence completed repairing the 8 transmissions in 2 days.

Thus, assuming that Clarence repaired the eight transmissions using 2 days, he will likely repair 24 transmissions if he works for the next 6 days.
