Answer:
Tossing a coin twice; A ={no Heads}, B={at least 1 Head}
Step-by-step explanation:
Mutually exclusive:
If two events are mutually exclusive, if one events happen, the other cannot happen, and vice-versa.
Rolling a die; A={Rolling an even number}, B={Rolling a number greater than 4}
A die has the following outcomes: 1,2,3,4,5,6
Even numbers: 2,4,6
Greater than 4: 5, 6
6 is an outcome of both events A and B, so they are not mutually exclusive.
Picking a card; A= {Selecting a 7}, B={Selecting a Heart}
Cards numbered from 1 to 13, each number with 4 types. So we can have a card of hearts numbered 7, which means that these events are not mutually exclusive.
Tossing a coin twice; A ={no Heads}, B={at least 1 Head}
If you get no heads, the probability of at least 1 head is 0.
If you get at least 1 head, the probability of no heads is 0.
This means that this is the answer, that is, these events are mutually exclusive.
Rolling two 6-sided dice; A={rolling a sum of 4}, B={rolling a 3 on one die}
(3,1) or (1,3) has a sum of 4 and a 3 on one die, which means that these events are not mutually exclusive.
Show work to determine the value of x.
ok so since the total measurement is 180° and you know that 1 of the sides is 40° and the other 2 are the same you will just need to subtract 40 from 180 and split that in half
here's the formula
[tex](180 - 40) \div 2 = \\ 140 \div 2 = \\ 70[/tex]
therefore
x=70°
bank wishing to increase its customer base advertises that it has the fastest service and that virtually all of its customers are served in less than 9 minutes. A management scientist has studied the service times and concluded that service times are exponentially distributed with a mean of 6 minutes. Determine what the bank means when it claims 'virtually all' its customers are served in under 9 minutes. Proportion of customers served in under 9 minutes
Answer:
"0.7769" is the right approach. A further explanation is given below.
Step-by-step explanation:
According to the question,
The parameter for the exponential distribution,
μ = 6
x = 9
Now,
⇒ [tex]P(X < 9) = 1 - exp ( \frac{-x}{\mu} )[/tex]
On substituting the given values in the above equation, we get
⇒ [tex]= 1 - exp (\frac{-9}{6} )[/tex]
⇒ [tex]=1-exp(-1.5)[/tex]
⇒ [tex]=1-0.2231[/tex]
⇒ [tex]=0.7769[/tex]
Find the value of x and the measure of the missing angle labeled A:
Answer:
below with explaination
Step-by-step explanation:
angle A + angle B + angle C = 180
x+x+37+x+67=180
3x+104=180
3x=180-104
3x=76
x=76÷3
x=25.3
angle A = 62.3

Lisa wants to measure the height of a tree. She sights the top of the tree, using a mirror that is lying flat on the ground. The mirror is 38 ft from the tree, and
Lisa is standing 6.2 ft from the mirror, as shown in the figure. Her eyes are 6 ft above the ground. How tall is the tree? Round your answer to the nearest foot.
(The figure is not drawn to scale.)
Answer:
37
Step-by-step explanation:
38 times 6 divided by 6.2
228/6.2 = 36.774....
Round to meter is 37

You are given data on number of radio ads and sales for a local department store. You had observations for 20 months. The correlation between ads and sales is 0.40. Does this indicate a positive and significant relationship between ads and sales at the 5% level of significance
Answer:
"No" would be the appropriate response. A further explanation is provided below.
Step-by-step explanation:
According to the question,
Number of observations,
n = 20
Significance level,
d = 5%
i.e.,
= 0.05
Calculated correlation,
= 0.40
Critical correlation value will be:
= 0.444
According to the question, we can see that the calculated correlation i.e., "0.40" is far less than the critical correlation value i.e., "0.444". The null hypothesis has always been not rejected. Thus it doesn't indicate the significant relationship.So the above it the right response.

B. the function has more than one x-intercept
O c. the function has exactly one x-intercept
D. the function has no x-intercepts
The function has exactly one x-intercept.
Option C is the correct answer.
What is a function?
A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
Based on the table of values provided, we can see that as x increases, y also increases.
This means that the function is increasing function.
Furthermore,
Since the y-values are negative for small x-values and positive for large
x-values, there must be at least one x-intercept where the function changes sign.
So,
We can conclude that the function that generated the table of values has exactly one x-intercept.
Thus,
The function has exactly one x-intercept.

Jessica's school bus stop is 60 yards from her house. For a normal school week, how many feet will Jessica walk to and from the bus stop.
Answer:
1,800 feet
Step-by-step explanation:
Assuming that the normal school week is 5 days, she will walk for 5 days to and from. Each day she will walk 120 yards to and from the stop. Multiply that number by 5 and you get your answer of 600 yards. The answer is wanted in feet, so you have to consider yards to feet conversions. 1 yard is three feet. Therefore, you multiply 600 by 3 and you get your answer in feet.
