What are m and b in the linear equation, using the common meanings of m and b?



1 + 4x + 6 - x = y

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.

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.

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.

"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

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.

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

Triangle EFG and EHG are two right triangles.

[tex]m\angle HEG=35^\circ[/tex]

[tex]m\angle FGE=30^\circ[/tex]

To find:

The values of x and y.

Solution:

In triangle EFG,

[tex]m\angle EFG+m\angle FGE+m\angle FEG=180^\circ[/tex]        [Angle sum property]

[tex]90^\circ+30^\circ+(x+35)^\circ=180^\circ[/tex]

[tex](x+155)^\circ=180^\circ[/tex]

[tex]x+155=180[/tex]

[tex]x=180-155[/tex]

[tex]x=25[/tex]

In triangle EHG,

[tex]m\angle EHG+m\angle HEG+m\angle EGH=180^\circ[/tex]        [Angle sum property]

[tex]90^\circ+35^\circ+(y+30)^\circ=180^\circ[/tex]

[tex](y+155)^\circ=180^\circ[/tex]

[tex]y+155=180[/tex]

[tex]y=180-155[/tex]

[tex]y=25[/tex]

Therefore, the value of x is 25 and the value of y is also 25.

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

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

148

(-9 +61) - (5-101)

(-9 +61) = 52

(5-101) = -96

So, 52 - ( - 96 )

=> 52 + 96

=> 148

Hope it helps!

Answer:

1/5 that's what I think to

Answer: (2,30), (5,66)

Step-by-step explanation: I truly don’t know if this is correct, but at the beginning, the crystal was already 6 mm. She then realized it increased 12 mm every hour, so if one hour passed, it would be 12+6= 18. Okay, so now that we know that, we multiple the hours by 12 and then add the 6.

12x2= 24

24+ 6= 30,

12x5= 60

60+6= 66
