Answer:
1100
Step-by-step explanation:
price = 1500
discount= 15%
15% of 1500 = (15/100)*1500= 15*15= 225
so selling price = 1275
profit is selling price - cost price
1275 - CP = 175
CP = 1275-175= 1100

Four expressions are shown:
A. 10x + 6
B. 12x + 4
C. 2(5x + 3)
D. 2(6x + 2)
Which two expressions are equivalent to 2(5x + 2 + x)? (1 point)
A and C
B and D
A and D
B and C
Answer:
B and D
Step-by-step explanation:
Simplify the given expression as shown below:
2(5x+2+x)= 2(6x+2) = D
Also
2(6x+2) = (2×6x) + (2×2)= 12x + 4 = B
Hence Both B and D are equivalent to 2(5x+2+x)
Students majoring in psychology surveyed 200 of their fellow students about their dreams. The results of the survey are shown in the Venn diagram. Let B be the event that the participant dreams in black and white and let C be the event that the participant dreams in color.
What is the probability that a randomly selected participant dreams in black and white or color?
Answer:
0.13
Step-by-step explanation:
4/200=0.02 12/200=0.06 10/200=0.05
0/02+0.06+0.05=0.13
The probability that a randomly selected participant dreams in black and white or color is 0.13.
What is probability ?"Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Math to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen. This is the basic probability theory, which is also used in the probability distribution, where you will learn the possibility of outcomes for a random experiment. "
Probability of all black = 4/200=0.02
Probability of all white = 12/200=0.06
Probability of all other color = 10/200=0.05
So, probability that a randomly selected participant dreams in black and white or color =0.02+0.06+0.05=0.13
Hence, the probability that a randomly selected participant dreams in black and white or color = 0.13

0% of the students on a field trip love the museum. If there are 0 students on the field trip, how many love the museum?
Answer:
0 students love the museum
Step-by-step explanation:
since the percentage of students that love the museum is zero, no matter how many students went, the number of people who like the museum will always be 0
now if 100 students went and 32% loved the field trip, then you would take 32% of the amount of students who went, to find the exact number of students who liked the field trip
32% of 100 is 32, so in my example, 32 people loved the museum

Annika was having fun playing poker. She needed the next two cards dealt to be diamonds so she could make a flush (five cards of the same suit). There are 15 cards left in the deck, and five are diamonds. What is the probability that the two cards dealt to Annika (without replacement) will both be diamonds?
a. 13%
b. 29%
c. 33%
d. 10%
Answer:
d. 10%
Step-by-step explanation:
1. Information to know
15 cards left in the deck, and 5 are diamond, to find the probability of the next 2 cards being diamond, one has to find the probability of the 1st card as a diamond, and then multiply it by the probability of the 2nd card being a diamond.
Remember, probability is;
[tex]\frac{favorable-outcomes}{total-outcomes}[/tex]
2. Find probability 1
favorable out comes; diamond = 5
total outcomes; total cards = 15
probability is; [tex]\frac{5}{15}[/tex]
Simplified; [tex]\frac{1}{3}[/tex]
3. Finding probability 2
If the last card drawn was a diamond then the new numbers will be
favorable outcomes; 4
total outcomes; 14
Probability is; [tex]\frac{4}{14}[/tex]
Simplified; [tex]\frac{2}{7}[/tex]
4. Total probability
Now, one has to multiply the first probability by the second probability to find the probability of the event;
[tex]\frac{1}{3} * \frac{2}{7}[/tex]
= [tex]\frac{2}{21}[/tex]
= 0.095238

A steel cable consists of eight high-strength steel strands. The strength of each strand can be modeled by a lognormal random variable with a mean value of 50 kips and a coefficient of variation of 10%. What is the probability that the weakest strand will have a strength less than 40 kips?
Answer:
P(X< 40) = 0.014367
Step-by-step explanation:
From the given information:
Suppose X denotes the strength of each steel strand & X follows the lognormal distribution with a mean value [tex]\mu_x[/tex] = 50 kips & coefficient of variation CV = 10%
Using the formula for the coefficient of variation CV
[tex]cv = \dfrac{\sigma_x}{\mu_x}[/tex]
[tex]0.10 = \dfrac{\sigma_x}{50}[/tex]
[tex]\sigma_x = 50 (0.10)[/tex]
[tex]\sigma_x = 5[/tex]
By applying the mean and mean & variance from the lognormal distribution, we have:
[tex]\dfrac{\sigma_x^2}{\mu_x}= \dfrac{\{exp(2 \mu + \sigma^2)\} (exp(\sigma^2))-1}{exp( \mu + \dfrac{\sigma^2}{2} \}}[/tex]
[tex]\dfrac{5^2}{50}= \dfrac{\{exp(2( \mu + \dfrac{\sigma^2}{2})) \} (exp(\sigma^2))-1}{exp( \mu + \dfrac{\sigma^2}{2} \}}[/tex]
[tex]\dfrac{5^2}{50}= exp \{ 2 ( \mu + \dfrac{\sigma^2}{2}) - ( \mu + \dfrac{\sigma^2}{2}) \} \{ ( exp ( \sigma^2))-1 \}[/tex]
[tex]\dfrac{5^2}{50}=exp \{(\mu + \dfrac{\sigma^2}{2}) \} {(exp (\sigma^2))-1 \}[/tex]
[tex]\dfrac{5^2}{50}=50 \{ (exp (\sigma^2 )) -1 \}[/tex]
[tex]\dfrac{25}{50 \times 50 }= ( exp (\sigma^2 )) -1[/tex]
[tex]exp( \sigma^2) = \dfrac{25}{50 \times 50}+ 1[/tex]
[tex]exp( \sigma^2) = (\dfrac{25+2500}{2500 })[/tex]
[tex]exp( \sigma^2) =1.01[/tex]
[tex]\sigma^2 = In (1.01)[/tex]
[tex]\mathbf {\sigma^2 = 0.00995}[/tex]
However, the next process is to replace the value of [tex]\sigma^2[/tex] into the logman distributions mean.
[tex]\mu_x = exp ( \mu + \dfrac{\sigma^2}{2})[/tex]
[tex]50 = exp ( \mu + \dfrac{\sigma^2}{2})[/tex]
[tex]50 = exp ( \mu + \dfrac{0.00995}{2})[/tex]
[tex]In(50) = ( \mu + \dfrac{0.00995}{2})[/tex]
3.912023 = μ +0.004975
μ = 3.907048
Now, we know our mean to be 3.907048 and the variance to be 0.00995.
Therefore, the probability that the weakest strand will have a strength of fewer than 40 kips can be computed as follows:
P(X< 40) = P(In(x) < In(40))
[tex]P(X<40) = P(\dfrac{In(x) - \mu}{\sigma} < \dfrac{In(40) - \mu}{\sigma})[/tex]
since;
[tex]\sigma^2 = 0.00995 \\ \\ \sigma = \sqrt{0.00995} \\ \\ \sigma = 0.0998[/tex]
[tex]P(X<40) = P(Z < \dfrac{In(40) - 3.907048}{0.0998})[/tex]
P(X< 40) = P(Z < -2.18712)
Using the Excel formula =(=NORMDIST (-2.18712)
P(X< 40) = 0.014367

Researchers want to test the effects of a new weight loss program. They believe that gender is a significant factor. The participants are divided by gender. Then, within each group, participants are randomly assigned to either the treatment or control group. Which of the following would be the most effective to test the effects of the new weight loss program?
a) Alongitudinal observational study
b) A matched-pair design experiment
c) A randomized block design experiment
d) A completely randomized design experiment
Answer:
C: A randomized block design experiment
Step-by-step explanation:
We are told the participants are divided by gender into groups which we can call blocks. Then, within each group, they are randomly assigned to either the treatment or control group. This means they are assigned treatments within each block.
A randomized block design is defined as an experimental design whereby the experimental units are divided into groups which we call blocks. After that treatments will be randomly assigned to the experimental units within each of the blocks.
Thus, this corresponds with our question and we can say it's a randomized block design experiment.

Elena walked 12 miles. Then she walked 0.25 that distance. How far did she walk all together? Select all that apply. A: 12+0.25∙12 B: 12(1+0.25) C: 12∙1.25 D: 12∙0.25 E: 12+0.25
Answer:
Step-by-step explanation:
If Elena walk 12 miles, and then 0.25 that distance
0.25=1/4
12*1/4=3 miles is 1/4 of the distance
she walked in total 12+3=15 miles
choice A =12+12*1/4
Elena walked a total 12(1+0.25) distance.
What is a distance?The distance is the total movement of an object without any regard to direction.
First Elena walked 12 miles.
Then walked 0.25 or (1/4)th of 12 miles
i.e. 12 * (1/4) = 3
The total distance Elena walked is
12+3 = 15 miles or
12 + (1/4)*12 = 12(1+0.25)
Hence, 12(1+0.25) is the total distance walked by Elena.
