Answer:

$14. \\841\rightarrow 800\\\\15.\\750$

Step-by-step explanation:

14:

Round the highest place means keeping the farther non-zero digit to the left, then rounding. Therefore, there should only be one non-zero digit in our final answer. The only answer choice that follows this <em>and</em> correctly rounds is $\boxed{841\rightarrow 800}$

15:

There are 30 days in November. Therefore, the number of pages typed is equal to $30\cdot 25=\boxed{750}$

Below is a drawing of a wall that is to be covered with either wallpaper or paint. The wall is 8 ft. high and

Snowcat [4.5K]

84 sq. ft of the wall has to be covered with paint or wallpaper.

Step-by-step explanation:

Step 1: Find the area of wallpaper to be covered by calculating the area of the wall and subtracting the areas of the window, mirror and fireplace from it. All are rectangular in shape with are given by A = length × width

Area of the wall = 8 × 16 = 128 ft²

Area of the window = 18/12 × 14 = 1.5 × 14 = 21 ft² (since 1 ft = 12 in)

Area of the fireplace = 5 × 3 = 15 ft²

Area of the mirror = 4 × 2 = 8 ft²

Step 2: Calculate the area to be painted or covered with wallpaper

Area of the wall to be covered with paint or wallpaper = 128 - (21 + 15 + 8)

= 128 - 44

= 84 ft²

Answer:

(0.63789 ; 1.38211 )

Given that:

Mean, xbar = 1.01

Standard deviation, s = 0.29

Sample size, n = 7

Confidence interval : xbar ± margin of error

Margin of Error = Tcritical * s/sqrt(n)

Degree of freedom (df) = n - 1 = 7 - 1 = 6

Hence Tcritical = 3.143

Margin of Error = 3.143 * 0.29/sqrt(6)

Margin of error = 0.37211

Lower boundary = (1.01 - 0.37211) = 0.63789

Upper boundary = (1.01 + 0.37211) = 1.38211

(0.63789 ; 1.38211 )

Question 3 of 10

MrMuchimi

Answer:

The point-slope form of the line is:

$y + 4 = 4(x+3)$

Hence, option B is correct.

Step-by-step explanation:

We know the point-slope form of the line equation is

$y-y_1=m\left(x-x_1\right)$

where

m is the slope of the line

(x₁, y₁) is the point

Given

The slope m = 4

From the graph, we can take the point (-3, -4)

So, in our case:

(x₁, y₁) = (-3, -4)

m = 4

now substituting m = 4 and (x₁, y₁) = (-3, -4) in the point-slope form of the line equation

$y-y_1=m\left(x-x_1\right)$

$y - (-4) = 4(x - (-3))$

$y + 4 = 4(x+3)$

Therefore, the point-slope form of the line is:

$y + 4 = 4(x+3)$

Hence, option B is correct.

The graph of the line is also attached.
