Find the angle measures given the figure is a rhombus.

levacccp [35]

Answer:

solution,

In rhombus,diagonal bisects the angle,

<ABD+<DBC+<C=180°

or, <1+<1+56=180°

or, 2<1=180°-56°

or, 2<1=124

or, <1=124/2

<1=62°

hope this helps...

Good luck on your assignment..

Students conducted a study of different sized containers and found that the box shown held 240 blocks. What is the empirical rat

N76 [4]

Answer:

B. 2 blocks per cubic inch

Step-by-step explanation:

The volume in cubic inches is the product of the dimensions in inches. The ratio of blocks per cubic inch is found by dividing the number blocks by the number of cubic inches. (Effectively, "per" means "divided by".)

(240 blocks)/((6 in)(4 in)(5 in)) = 240/120 blocks/in³ = 2 blocks/in³

The length of a movie falls on a normal distribution. About 95% of movies fall between 75 minutes and 163 minutes.

ioda

Answer:

a) x = 119 minutes

the mean value for average movie length in minutes is 119 minutes

b) margin of error M.E = 44 minutes

Note; Since the number of samples used is not given, the standard deviation r cannot be calculated using the equation

M.E = zr/√n

Step-by-step explanation:

Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.

The confidence interval of a statistical data can be written as.

x+/-zr/√n

x+/-M.E

M.E = zr/√n

Given that;

M.E = margin of error

Mean = x

Standard deviation = r

Number of samples = n

Confidence interval = 95%

z value (at 95% confidence) = 1.96

a) The mean value x can be calculated as;

x = (a+b)/2

Where a and b are the lower and upper bounds of the confidence interval;

a = 75 minutes

b = 163 minutes

substituting the values;

x = (75+163)/2

x = 119 minutes

the mean value for average movie length in minutes is 119 minutes

b) the margin of error M.E can be calculated as;

M.E = (b-a)/2

Substituting the values;

M.E = (163-75)/2

M.E = 44 minutes

Since the number of samples used is not given, the standard deviation r cannot be calculated using the equation

M.E = zr/√n
