Answer:

angle 5 = 17 degrees

angle 6 = 129 degrees

Step-by-step explanation:

Start by finding angle 5 by doing 90+39+x+34=180

You get 17 degrees for angle 5

Then, find angle 6 by doing 17+34+x=180, which is 129 degrees.

Answer:

$9.00

Step-by-step explanation:

If the price is at 30% discount, this means it is 100-30 = 70% of the original price.

$70 \% \ of \ original \ price = \$ 6.30\\\\\ original \ price = 6.30 \div 70 \%\\\\= 6.30 \times \frac{100}{70}\\\\=\frac{630}{70}\\\\= 9$

Hence, original price is $9.00.

The area of a square is 225cm². On the map drawn to scale 1 : 3 find the area of the square

Olin [163]

Answer:

25 cm^2

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

Area if a square = length²

225 = length²

length = √225

length = 15

if the map is drawn to scale of 1 : 3

the length on the map = 15/3 = 5

area of the square 5 x 5 = 25

Think about a population proportion that you may be interested in and propose a confidence interval problem for this parameter.

o-na [289]

Answer: The confidence interval would be (0.2928,0.3672).

Step-by-step explanation:

Since we have given that

Total number of vehicles = 432

Number of SUVs sold = 142

So, it becomes,

$\hat{p}=\dfrac{x}{n}=\dfrac{142}{432}=0.33$

At 90% confidence interval,

z = 1.645

So, the confidence interval would be

$\hat{p}\pm z\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\=0.33\pm 1.645\sqrt{\dfrac{0.33\times 0.67}{432}}\\\\=0.33\pm 0.0372\\\\=(0.33-0.0372,0.33+0.0372)\\\\=(0.2928,0.3672)$

Hence, the confidence interval would be (0.2928,0.3672).
