Answer:

Apply trigonometric function for triangle ABC:

7.

sin A = BC/BA = 6/7.2 = 0.83

A = arcsin(0.83) = 56.44

8.

tan B = AC/BC = 4/6 = 0.67

B = arctan(0.67) = 33.69 deg

Hope this helps!

The correlation coefficient r between the age of a homeowner, x, and the number of years remaining on the homeowner's mortgage,

marysya [2.9K]

Solution: We are given that the correlation coefficient between the age of a homeowner, x , and the number of years remaining on the homeowner's mortgage, y, is 0.485

We know that coefficient of determination is the percent of the variation in the dependent variable that is explained by the independent variable. The coefficient of determination is the square of correlation coefficient and is denoted by $R^{2}$

Therefore, we have:

$R^{2}= 0.485^{2}=0.235 or 23.5\%$ denotes

Hence the option 23.5% is correct

grigory [225]

5B + B = 20

6B = 20

B = 20 / 6

= 10/ 3 hrs

A = 5 ( 10/3 + 2)

= 5 (16/3)

= 80 / 3 hrs

Brian traveled 10/3 hours and Annie traveled 80/3 hours.

240 televisions of a store are are high definition. These 240 televisions make up 80% of the televisions. How many televisions a

Eddi Din [679]

Answer:

300

Step-by-step explanation:

Let's call N the total number of televisions. We have that 240 televisions make up of 80% of the total number of televisions, so we can rewrite it as

$0.80 N = 240$

where 0.80 means 80 % ( $\frac{80}{100}=0.8$ . By solving the equation above, we find

$N=\frac{240}{0.80}=300$

So, the total number of televisions is 300.

n airline knows from experience that the distribution of the number of suitcases that get lost each week on a certain route is a

Sedbober [7]

Answer: 0.8313

Step-by-step explanation:

As per given we have,

$\mu=15.5$ $\sigma= 3.6$

Also, the distribution of the number of suitcases that get lost each week on a certain route is approximately normal.

Since , $z=\dfrac{x-\mu}{\sigma}$

z-score corresponds to x= 10: $z=\dfrac{10-15.5}{3.6}\approx-1.53$

z-score corresponds to x= 20: $z=\dfrac{20-15.5}{3.6}=1.25$

P-value = $P(10$

$=P(z$

Hence, the probability that during a given week the airline will lose between 10 and 20 suitcases = 0.8313
