Assume the birth of a boy or a girl is equally likely. The probability that a single child is born a girl is one-half. What is the probability that the next child born to the same familiy will also be a girl?.
There is a 1/4 probability that the family's next child will be a girl.
What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
So, the probability that the next child born will also be a girl:
We know that:
There is a 50% chance that a female will be the only kid born.
That is: 1/2
The likelihood that the family's subsequent kid will be a girl is:
1/2 * 1/2 = 1/4
Therefore, there is a 1/4 probability that the family's next child will be a girl.

Ernesto guesses there are 69 marbles in a jar, but there are actually 60.
What is the percent error in Ernesto's guess?
Answer:
15%
Step-by-step explanation:
Since the problem is to find how much 69 is as a percent if 60 is 100%, we can use a rule of three, simple, direct proportion to do it:
60 = 100%
68 = x
x = 69x100/60
x = 115
That means 69 is 115% of 60, which means that the error is of:
115 - 100 = 15%

Exhibit 6-3 The weight of football players is normally distributed with a mean of 200 pounds and a standard deviation of 25 pounds. Refer to Exhibit 6-3. What is the minimum weight of the middle 95% of the players? a. 196 b. 151 c. 249 d. None of the answers is correct.
Option B, The center 95% of players had an average weight of 151 pounds.
Football players' weights have a mean of 200 pounds as well as a standard deviation of 25 pounds, which corresponds to a normal distribution.
So, let x represent a football player's weight.
X ≅ N(200, (25)²)
The minimal weight of the center 95% of the members is
P(X > 95) = P((95 - 200) ÷ 25) < (X - µ) ÷ σ)
P(X > 95) = P(-4.2 < z)
P(X > 95) = - P(z < -4.2)
P(X > 95) = 0.1512
The needed percentage is 0.1512 × 100 = 151.2 percent.

6. If mLABE = 2n +7 and mZEBF = 4n-13, find mZABE.
Answer: 18°
Step-by-step explanation:
The question doesn’t state where F is in relation to A, B or E, so we have to guess. Here are two guesses.
If ABF is a straight line then ∠ABE+∠EBF=180, so 2n+7+4n-13=180, 6n-6=180.
Divide each side by 6: n-1=30 so n=31 and m∠ABE=2n+7=2×31+7=62+7=69°.
If BF bisects ∠ABE, then ∠ABE=2×∠EBF, so 2n+7=2(4n-13)=8n-26. So 6n=33 and, dividing both sides by 3: 2n=11. Therefore m∠ABE=2n+7=11+7=18°.

let p = pennies and n = nickels
p + n = 31 coins
p = 31 - n

According to the perpendicular bisector theorem, the statement that is true is: B. BI = BK.
What is the Perpendicular Bisector Theorem?The perpendicular bisector theorem states that if a line segment bisects another line segment perpendicularly, therefore, any point on the perpendicular would be the same distance from the endpoints of each of the line segment that was bisected.
In the diagram above, we are told that line segment AB is a perpendicular bisector of line segment IK. This means that, according to the perpendicular bisector theorem, any point on line segment AB, would be equidistant to the endpoints of line segment IK.
This implies that:
The length of BI is the same as the length of BK. Thus, the correct answer is: B. BI = BK.

a child is 40 inches tall, which places her at the 90th percentile of all children of similar age. the heights for children of this age form an approximately normal distribution with a mean of 38 inches. based on this information, what is the standard deviation of the heights of all children of this age?
Since the mean height of all children this age is 38 inches, the z-score is 1.282, and the child's height is 40 inches, the standard deviation of all children's heights will be 1561.
What is standard deviation?The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a larger range, a low standard deviation suggests that the values tend to be near to the established mean. The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation indicates that the data are grouped around the mean, whereas a high standard deviation shows that the data are more dispersed.
Here,
The z-score which separates the top 10% of a normally distributed
population is 1.282.
Since z = (x-u)/sigma
1.282 = (40-38)/sigma
sigma = 2/1.282
sigma = 1/0.641 = 1561
The standard deviation of the heights of all children of this age will be 1561 as mean is 38 inch and z-score is 1.282 as well as the height of child is 40 inch.

You have $8.80 in Pennie’s and nickels you have twice as many nickels as pennies write a system of linear equations that model the situation how many coins do you have
Answer:
Step-by-step explanation:
Let p be the number of pennies and n be the number of nickels. As you have $8.80 in total (given that pennies are worth $0.01 and nickels are worth $0.05)
0.01p + 0.05n = 8.80
You also know that there are twice as many nickels than pennies (or alternatively, there are 2 nickels for every penny).
n = 2p
You can substitute this value of n into the first equation
0.01p + 0.05n = 8.80
0.01p + 0.05(2p) = 8.80
0.01p + 0.10p = 8.80 (multiplying out the brackets)
0.11p = 8.80 (collecting the p's)
p = 80
Putting this back into the second equation
n = 2p
n = 2(80) = 160
So there are 160 nickels and 80 pennies.
You can put this back into the first equation to check it.
0.01p + 0.05n = 8.80
0.01(80) + 0.05(160) = 0.80 + 8 =8.80
