Answer:

The slope of ladder is not within the safe range  .

Step-by-step explanation:

Given as :

The height of the ladder up a wall = h = 2 meters

The distance of base of ladder from the wall = x = 0.4 meters

The estimated safety range of slope of ladder is between 6.3 and 9.5

Let The slope of the ladder = x

<u>According to question</u>

slope of the ladder = \dfrac{\textrm height of ladder up wall}{\textrm distance of base of ladder from wall}

Or, x = \dfrac{2 meters}{0.4 meters}

Or, x = 5

So, The slope of the ladder = x = 5

Since The estimated range of slope between 6.3 and 9.5

And The calculate slope of ladder = 5

Hence, The slope of ladder is not within the safe range  . Answer

What is the standard error of the proportion if 80% of the 1,200 respondents in a yes/no survey answered "no"?
saw5 [17]
Standard error for a sample proportion, p = 0.8, n = 1200

SE= \sqrt{ \frac{p(1-p)}{1200} } = \sqrt{ \frac{0.8(1-0.8)}{1200} } \approx 0.015 \times 100\%=1.15\%

. Express the ratios in its simplest form (a) 15:12 (b) 42:1
telo118 [61]

Answer:

See answers below

Step-by-step explanation:

Given the following ratios. We are to express them in their simplest forms

15:12

= 15/12

= (3*5)/(3*4)

= 3/3 * 5/4

= 5/4

b) 42:1

= 42/1

= 42

Given that  2:x :: 4:6​

2/x = 4/6

Cross multiply

4x = 2*6

4x = 12

x = 12/4

x = 3

Hence the value of x is 3

Describe the locus that the figure represents.
Harlamova29_29 [7]
The correct answer is: <span>all points equidistant from point A and point B

Explanation:

If you draw lines from Point A to the line and and from Point B to the line (perpendicular to the line), you would see that the distances from both these points to the line would be the same. Likewise if apply the symmetry argument on both of the points, you would find out that all points on the line would be equidistant from point A and point B. Hence Option (B) is correct.</span>

James baked 5 1/4 dozen peanut butter cookies and 4 5/6 dozen oatmeal cookies for a bake sale what was the number of dozen cooki
Doss [256]

Answer:

10\frac{1}{12} dozen

Step-by-step explanation:

\frac{1}{4} × 3 = \frac{3}{12}

\frac{5}{6} × 2 = \frac{10}{12}

\frac{3}{12}  + \frac{10}{12}  = \frac{13}{12}

\frac{13}{12} is equal to 1\frac{1}{12}

5 + 4 = 9 + 1\frac{1}{12} = 10\frac{1}{12} dozen
