The actual weight of a 2-pound sacks of salted peanuts is found to be normally distributed with a mean equal to 2.04 pounds and a standard deviation of 0.25 pounds. Given the information, the probability of a sack weighing more than 2.40 pounds is 0.4251. True or False.
Answer:
False
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Mean equal to 2.04 pounds and a standard deviation of 0.25 pounds.
This means that [tex]\mu = 2.04, \sigma = 0.25[/tex]
The probability of a sack weighing more than 2.40 pounds is 0.4251. True or False.
We have to find 1 subtracted by the vpalue of Z when X = 2.4. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{2.4 - 2.04}{0.25}[/tex]
[tex]Z = 1.44[/tex]
[tex]Z = 1.44[/tex] has a pvalue of 0.9251
1 - 0.9251 = 0.0749
The probability is 0.0749, which means that the answer is False.

sprinter started his race slowly and then increased his speed by 14.8 miles per hour to reach a top speed of 23 miles per hour. What was the sprinter's speed before he increased his speed?
Answer:
8.2
Step-by-step explanation: i think its 8.2
i dont know tho
The sprinter's speed before he increased his speed is 8.2 miles per hour.
What is Speed?
Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.
Here, Change in Speed = 14.8 miles per hour
Top speed = 23 miles per hour
Actual old Speed = Top Speed - increased speed
= 23 - 14.8
= 8.2 miles per hour
Thus, the sprinter's speed before he increased his speed is 8.2 miles per hour.

Answer:
cone: 138.16 in²
pyramid: 352 m²
Step-by-step explanation:
Use the appropriate formula from your list of area and volume formulas.
Area of a Cone
A = πr(r +h) . . . . . where r is the radius and h is the slant height
The radius is half the diameter, so is 4 inches.
A = π(4 in)(4 in + 7 in) = 44π in² ≈ 138.16 in²
__
Lateral Area of a Square Pyramid
A = 2sh . . . . . where s is the side length of the base and h is the slant height
A = 2(8 m)(22 m) = 352 m²

L (3x+y = 8
1x - 4y = -6
m{$*=*=230
NS 4x – 3y = 2
12% -8y = -12
Answer:
B. L and N
Step-by-step explanation:
Let's solve each system
✔️System L:
3x + y = 8 => Eqn. 1
x - 4y = -6 => Eqn. 2
x = -6 + 4y
Substitute x = (-6 + 4y) in eqn. 1
3(-6 + 4y) + y = 8
-18 + 12y + y = 8
-18 + 13y = 8
13y = 8 + 18
13y = 26
y = 26/13
y = 2
Substitute y = 2 into Eqn. 2
x - 4y = -6
x - 4(2) = -6
x - 8 = -6
x = -6 + 8
x = 2
Solution to system L = (2, 2)
✔️System M:
4x - 3y = 2 => Eqn. 1
5x - 4y = -30 => Eqn. 2
Multiply eqn 1 by 5, and eqn. 2 by 4
20x - 15y = 10
20x - 16y = -120
Subtract
y = 130
Substitute y = 130 into eqn. 1
4x - 3(130) = 2
4x - 390 = 2
4x = 2 + 390
4x = 392
x = 392/4 = 98
Solution to system M = (98, 130)
✔️System N:
4x - 3y = 2 =>Eqn. 1
2x - 8y = -12 => Eqn. 2
Multiply Eqn. 1 by 2, and eqn. 2 by 4
8x - 6y = 4
8x - 32y = -48
Subtract
26y = 52
y = 52/26
y = 2
Substitute y = 2 into eqn. 1
4x - 3(2) = 2
4x - 6 = 2
4x = 2 + 6
4x = 8
x = 8/4
x = 2
Solution to system N = (2, 2)

D. 4v3 units
Answer: i think the answer is B or C sorry
Step-by-step explanation:
have a nice day
The length of the radius of circle A is 24 units. The correct answer would be an option (A).
What is an arc?The arc is a portion of the circumference of a circle. The circumference of a circle is the distance or perimeter around a circle.
As per the question, we have
Arc length BC = 20π units and θ = 150°
The formula for calculating the arc states that:
Arc length = 2πr (θ/360)
Where r = the radius of the circle,
π = pi = 3.14
θ = the angle (in degrees) subtended by an arc at the center of the circle.
Substitute the known values, and we get
20π = 2πr (150/360)
10 = r (5/12)
r = 120/5
r = 24
Thus, the length of the radius of circle A is 24 units.

A game of chance involves rolling a 16-sided die once. If a number from 1 to 3 comes up, you win 4 dollars. If the number 4 or 5 comes up, you win 7 dollars. If any other number comes up, you lose. If it costs 5 dollars to play, what is your expected net winnings
Answer:
-$1.8
or loss of $1.8
Step-by-step explanation:
Given the following parameters, we have
The probability of winning $4 is 3/16
The probability of winning $7 is 2/16
The probability of losing $5 is 11/16
E(X) = (4 * 3/16) + (7 * 2/16) + (-5 * 11/16)
= 12/16 + 14/16 - 55/16
= -29/16
= -1.8
Hence, your expected net "winnings" would be -$1.8. That's an expected loss of $1.8.
