Answer:

Angle BDA is 90°

(2x + 3) + 55 = 90

2x + 3 + 55 = 90

2x + 58 = 90

2x = 90 - 58

2x = 32

x = 32/2

<u>x = 16</u>

Hence,

x=16

x=16Angle BDA is 90°.

A sample of 20 joint specimens of a particular type gave a sample mean proportional limit stress of 8.41 mpa and a sample standa

For this problem, the confidence interval is the one we are looking for. Since the confidence level is not given, we assume that it is 95%.

The formula for the confidence interval is: mean ± t (α/2)(n-1) * s √1 + 1/n

Where:

<span>
</span>

α= 5%

α/2 = 2.5%

t 0.025, 19 = 2.093 (check t table)

n = 20

df = n – 1 = 20 – 1 = 19

So plugging in our values:

8.41 ± 2.093 * 0.77 √ 1 + 1/20

= 8.41 ± 2.093 * 0.77 (1.0247)

= 8.41 ± 2.093 * 0.789019

= 8.41 ± 1.65141676

Jana joined a music club that offered her 5 CDs for a total of 3.00 if she agreed to purchase an additional 10 CDs for 15.00 eac

Hunter-Best [27]

Answer:

Average price, excluding taxes, for each CD is <u>10.20</u>.

Step-by-step explanation:

Given:

Cost of first 5 CDs, $C_1 = 3.00$

Cost of each additional CD = 15.00

Now, cost of 10 additional CDs is the product of cost of one CD and total number of additional CDs. Therefore,

Cost of 10 additional CDs is, $C_2=15.00\times 10=150.00$

Now, total CDs purchased by Jana are, $N=5+10=15$

Total cost of the 15 CDs purchased is given as:

$C_T=C_1+C_2=3.00+150.00=153.00$

Now, average price, excluding taxes, for each CD is given as:

$\textrm{Average price}=\frac{\textrm{Total cost of purchase}}{\textrm{Total number of CDs purchased}}\\\\\textrm{Average price}=\frac{C_T}{N}=\frac{153.00}{15}=10.20$

Therefore, the average price, excluding taxes, for each CD is 10.20.

Solve for x (Angle relationship in Circles)

makkiz [27]

Step-by-step explanation:

$180 \degree - 102 \degree = \frac{1}{2} (x + 95\degree) \\ \\ \therefore \: 72 \degree = \frac{1}{2} (x + 95\degree) \\ \\ \therefore \: 72 \degree \times 2= (x + 95\degree) \\ \\ \therefore \: 144 \degree = x + 95\degree \\ \\ \therefore \:x = 144 \degree - 95\degree \\ \\ \huge \red{ \boxed{\therefore \:x = 49\degree}}$
