If you receive 25\% off an item costing $22.00, how much money do you save?
Answer:
5.50
Step-by-step explanation:
They save 5.50
Answer:
$5.50
Step-by-step explanation:
Hello! This is an easy one. If we are trying to find how much she is saving all we would need to do is multiply.
$22.00 * 25% = $5.50
If we are trying to find out the total with the discount all we would need to do is subtract.
22 - 5.5 = $16.50
Hope this helps!!

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]
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.

Answer:
the answer is B!
Step-by-step explanation:
because :
Jerry has = 150$
he "*DEPOSITED*" = 50$
(When the word deposit comes, it basically means we need to ADD)
therefore, 150 +50x = 500
(7 weeks) so,
150 + 50 * 7 = 500
see! my answer is correct !

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.

Answer:
{Segments, Geometric mean}
{PS and QS, RS}
{PS and PQ, PR}
{PQ and QS, QR}
Step-by-step explanation:
The three geometric mean relationships are derived from the similarity of the triangles the similarity proportions can be written 3 ways, each giving rise to one of the geometric mean relations.
short leg : long leg = SP/RS = RS/SQ ⇒ RS² = SP·SQ
short leg : hypotenuse = RP/PQ = PS/RP ⇒ RP² = PS·PQ
long leg : hypotenuse = RQ/QP = QS/RQ ⇒ RQ² = QS·QP
I find it easier to remember when I think of it as the segment from R is equal to the geometric mean of the two segments the other end is connected to.
__
segments PS and QS, gm RS
segments PS and PQ, gm PR
segments PQ and QS, gm QR

Answer:

Step-by-step explanation:
To determine whether the pipe welds in a nuclear power plant meet specifications, a random sample of welds is selected, and tests are conducted on each weld in the sample. Weld strength is measured as the force required to break the weld. Suppose the specifications state that mean strength of welds should exceed 100 lb/in2; the inspection team decides to test
H0:μ=100 versus Ha:μ>100.
Explain why it might be preferable to use this Ha rather than μ<100.
A. We want to determine if there is significant evidence that the mean strength of welds differs from 100 lb/in2. The current hypotheses correctly place the burden of proof on those who wish to assert that the specification is not satisfied.
B. We want to determine if there is significant evidence that the mean strength of welds is less than 100 lb/in2. The current hypotheses correctly place the burden of proof on those who wish to assert that the specification is not satisfied.
C. We want to determine if there is significant evidence that the mean strength of welds exceeds 100 lb/in2. The current hypotheses correctly place the burden of proof on those who wish to assert that the specification is satisfied.
D. We want to determine if there is significant evidence that the mean strength of welds equals 100 lb/in2. The current hypotheses correctly place the burden of proof on those who wish to assert that the specification is satisfied.
Answer:
C. We want to determine if there is significant evidence that the mean strength of welds exceeds 100 lb/in2. The current hypotheses correctly place the burden of proof on those who wish to assert that the specification is satisfied.
Step-by-step explanation:
Given
[tex]\mu = 100[/tex]
[tex]H_0:\mu = 100\\\\H_a:\mu > 100[/tex]
Required
State why it is preferred to [tex]Ha: \mu < 100[/tex]
From the question, we understand that the initial test is the force required to break the weld.
This represents the null hypothesis
Because the required force can not be less than the strength of the weld (it must match the force keeping the weld), the null hypothesis is represented as:
[tex]H_0:\mu = 100[/tex]
Reading the question further;
The specification requires that the mean strength should exceed 100
In inequalities, exceeds means greater than, and it is represented with >
So, the null hypothesis is rightly represented as:
[tex]H_a:\mu > 100[/tex]
Hence: (c) is true

10 POINTS PLS ANSWER
Answer:
Step-by-step explanation:
FGE is a straight line, and striaght lines measure 180 by definition. Therefore, x, angle BGA, and 55 all add together to equal 180. But notice that x and 55 are both marked with a single swish, meaning they are the same measure. So:
180 - 55 - 55 = x, so
x = 70
