Suppose a normal distribution has a mean of 98 and a standard deviation of
6. What is P(x292)?
O A. 0.16
B. 0.475
C. 0.84
D. 0.975
The z-score of the value P ( x < 92 ) is given by z = -1 with standard deviation of 6 is P ( x < 92 ) = 0.16
What is a z-score?The relationship between a value and the mean of a set of values is expressed numerically by a Z-score. The Z-score is computed using the standard deviations from the mean. A Z-score of zero indicates that the data point's score and the mean score are identical.
The Z-score is calculated using the formula:
z = (x - μ)/σ
where z: standard score
x: observed value
μ: mean of the sample
σ: standard deviation of the sample
Given data ,
Let the distribution be a normal distribution where
The mean of the data is μ = 98
The standard deviation is σ = 6
Now , the Z-score is determined by z = (x - μ)/σ
On simplifying , we get
when x = 92
P ( x < 92 ) is
z = ( 92 - 96 ) / 6
z = -1
So , the p value of P ( x < 92 ) is 0.1587
On rounding to the nearest value , we get
P ( x < 92 ) = 0.16
Hence , the z-score is solved

there is a bag filled with 6 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 that are different in colour?
Answer:
60/121
Step-by-step explanation:
There are two outcomes that are included in the event "2 different in color" -- either Red followed by Blue (RB) or Blue followed by Red (BR).
Probability of RB is [tex]\frac{5}{11}\times \frac{6}{11}=\frac{30}{121}[/tex] The denominator 11 does not change in the second fraction because you put the first marble back; still 11 marbles in the bag.
Probability of BR is [tex]\frac{6}{11} \times \frac{5}{11}=\frac{30}{121}[/tex]
Probability of RB or BR: add the probabilities to get 60/121.

Adrian took out a simple interest loan for $2000. The rate on this loan is 7% and he will pay it back in 5 years. How much money will Adrian owe at the end of 5 years including interest?
Answer:
i think its 700
Step-by-step explanation:
7%of 2000 is 140 and 140 x 5 is 700
Answer: $700 interest
Note that the formula for simple interest is I=Prt
1. Identify the Principal amount (P), rate (r), and time (t)
Principal amount=$2,000
Rate: 7% (0.07)
Time: 5 years
2. Plug the numbers into the formula; always make sure that the rate is in decimal form and the time is in years.

Help would be appreciated for this question!!!
Answer:
A
Step-by-step explanation:
Recall that sin = opposite over hypotenuse
For ∠A we are already given its opposite side length ( 2 ) however the hypotenuse has not been identified.
The triangle shown is a right triangle ( indicated by the little square on the bottom left ) which means that we can find a missing side length, more specifically the hypotenuse, using the Pythagorean theorem
[tex]a^2+b^2=c^2[/tex] where a and b = legs and c = hypotenuse
we are given that the legs = 2 and 4 and need to find the hypotenuse
That being said we plug in what we are given and solve for c
[tex]2^2+4^2=c^2\\2^2=4\\4^2=16\\16+4=20\\20=c^2[/tex]
In order to get the exact value of c we must get rid of the exponent.
To do so we can take the square root of both sides
[tex]\sqrt{20} =\sqrt{20} \\\sqrt{c^2} =c\\c=\sqrt{20}[/tex]
hence, the hypotenuse = √20
Now lets look back at the question
Find sin∠A to the nearest hundredth.
well remember sin = opposite over hypotenuse
The opposite of sin∠A is 2 and the hypotenuse is √20
Hence, sin∠A = [tex]\frac{2}{\sqrt{20} }[/tex] which is equivalent to .447213595
Our last step is to round to the nearest hundredth
We get the sin∠A = .45

Sabrina borrowed $350000 with a 0.5% interest rate from Bank of America to buy a new condo in orange beach how did it take Sabrina to pay if the loan if she ended up pay &26250 interest plz help me
Answer:
t = 2466.67 years (about 2466 years 8 months)
Step-by-step explanation:
Given: Total P+I (A) = $350000, Principal (P) = $26250, Rate (R) = 0.5%
To find: How long did it take Sabrina to pay if the loan if she ended up pay $26250 interest?
Formula: [tex]t = (1/r)(A/P - 1)[/tex]
Solution: To calculate your interest rate, you need to know the interest formula I/Pt = r to get your rate
First, converting R percent to r a decimal
r = R/100 = [tex]\frac{0.5 percent}{100}[/tex] = 0.005 per year,
then, solving our equation
t = (1/0.005)((350000/26250) - 1) = 2466.67
t = 2466.67 years
Therefore, it will take Sabrina 2466.67 years (about 2466 years 8 months) to pay off the loan.

1/10 of the M&M's in a bag are red and 1/5
are blue. What fraction of all the m&ms
are red and blue?
Answer:
3/10 of all the M & M's are red and blue.
Step-by-step explanation:
Given that 1/10 of the M & M's in a bag are red and 1/5 are blue, to determine what fraction of all the M & M's are red and blue, the following calculation must be performed:
1/10 = 0.10
1/5 = 2/10 = 0.20
1/10 + 2/10 = X
3/10 = X
Therefore, 3/10 of all the M & M's are red and blue.
