37.68 Anything in the hundredths column that is five or higher, would raise the tenths column by one number. 37.7 In your example the 8 is higher than 5, so the 6 is raised to a 7 for rounding.

Answer:

37.70

Step-by-step explanation:

In Arithmetic, a hundredth is one whole number divided by 100. After the dot, two places to the right is the home of the hundredths.

The point here is rounding up to the nearest hundredth the number 37.68

As a general rule, any amount greater than 0.5 or 0.05 we round up to the nearest tenth or hundredth.

In this case, rounding up to the nearest hundredth coincides with rounding up to the nearest tenth, for 37.70 = 37.7

Suppose that a regression line for some data transformed with logarithms predicts that when x equals 4, log(y) will equal 3.331.

deff fn [24]

Option D

The regression line predicts that at x = 4, y equals 2143

Solution:

Given that when x equals 4, log(y) will equal 3.331

To find: Find y when x equals 4

Since we have given that,

When x = 4,

$\text{ log } y = 3.331$

We need to find the value of 'y' when x = 4

$log_{10}y = 3.331$

Since it is logarithmic function with base 10, Raise to power of 10 on both sides,

$10^{log_{10}y} = 10^{3.331}\\\\\text{10 power log base 10 cancels, we get }\\\\y = 10^{3.331}\\\\y = 2142.89$

On rounding to nearest whole number, we get 2143

Thus Option D is correct

Lisa started to drive from Boston to Washington, DC, which is 440 miles away, at 8:00 AM. For the first four hours of her trip,

sukhopar [10]

Answer:

60 mph

Step-by-step explanation:

Given;

Total distance covered d = 440 miles

Average speed in the first 4 hours v1 = 50 mph

Total time taken for the whole trip t = 8:00 to 4:00pm

t = 16:00-8:00 = 8 hours

Firstly we need to calculate the distance covered during the first 4 hours;

d1 = average speed × time = v1 × t1

t1 = 4

d1 = 50 × 4 = 200 miles

Then we need to calculate the distance covered in the second period of the journey;

d = d1 + d2

d2 = d - d1

Substituting the values;

d2 = 440 - 200

d2 = 240 miles

The time taken for the second period of travel t2;

t2 = t -t1 = 8-4

t2 = 4 hours

Average speed = distance travelled ÷ time taken

The average speed for the second part of the trip v2 is;

v2 = d2 ÷ t2

Substituting t2 and d2;

v2 = 240 miles ÷ 4 hours

v2 = 60 mph

The average speed during the second part of the trip is 60 mph

saw5 [17]

Answer:

2 and 1 over 12

Step-by-step explanation:

$1 \frac{2}{3} \div \frac{4}{5} \\ \\ = \frac{1 \times 3 + 2}{3} \div \frac{4}{5} \\ \\ = \frac{5}{3} \times \frac{5}{4} \\ \\ = \frac{25}{12} \\ \\ = 2 \frac{1}{12} \\$
