Find The Value Of XA. 40 Degrees B. 50 Degrees C. 60 Degrees D. 100 Degrees

Answers

Answer 1

The value of x from the given figure is 40 degrees

Geometry

Geometry is a way of relating lines and angles using theorems;

circle theorems

To get the value of x, we will use the expression based on the circle theorem:

80 = 1/2(200 - x)

Cross multiply

80 * 2  = (200 - x)

160 = 200 - x

x = 200 - 160

x = 40

Hence the value of x from the given figure is 40 degrees

Suppose the consumer group used a sample size of 50 instead of 100 for each airline. When all other things remain the same, what effect would the decrease in sample size have on the interval?

Answers

Answer:

Width of confidence interval will increase.

Step-by-step explanation:

The sample size as an effect on the width of the confidence interval being calculated as it determines the value of the error margin. In general, increasing the sample size reduces the width of the confidence that interval while decrease in its value increases the error margin and hence the confidence interval.

Confidence interval :

Xbar ± Error margin

Error margin = Tcrit * s/ sqrt(n)

n = sample size

Being the denominator, a decrease in its value will result in an increase in error margin.

A pet store has 96 pets ( dogs, cats, birds) for sale. There are 3 more dog than cats. There are 9 less birds than cats. How many of each type of pet are in the shop?

Answers

Answer:

Cats = 34

Dogs = 37

birds = 25

Step-by-step explanation:

Let :

c = cats

d = dogs

b = birds

from the question, the following equation can be gotten

d = 3 + c  eqn 1

b = c - 9   eqn 2

c + d + b = 96 eqn 3

substitute for b and d in equation 3

3 + c + c - 9 + c = 96

3c - 6 = 96

3c = 102

c = 34

Substitute for d in eqn 1

d = 3 + 34 = 37

Substitute for b in eqn 2

34 - 9 = 25
