A company manufactures batteries in batches of 26 and there is a 3% rate of defects. Find the standard deviation for the number of defects per batch.
Answer:
The standard deviation for the number of defects per batch is 0.87.
Step-by-step explanation:
Let X denote the number of defective batteries per batch.
A company manufactures batteries in batches of n = 26.
It is provided that the rate of defects is, p = 0.03.
Each battery is defective independently of the others.
The random variable X follows a binomial distribution.
The standard deviation of a binomial distribution is:
[tex]\sigma=\sqrt{np(1-p)}[/tex]
Compute the standard deviation for the number of defects per batch as follows:
[tex]\sigma=\sqrt{np(1-p)}[/tex]
[tex]=\sqrt{26\times 0.03\times (1-0.03)}\\\\=0.86982757\\\\\approx 0.87[/tex]
Thus, the standard deviation for the number of defects per batch is 0.87.

How will increasing the level of confidence without changing the sample size affect the width of a confidence interval for a population mean?
Answer:
The width of the confidence interval is going to be wider
Step-by-step explanation:
When we Increase the level of confidence without changing the sample size the width of the confidence interval is going to be affected in the following way;
The margin of error (M.E) is going to be larger or be increased. This increase is due to the fact that the critical value is going to increase. Then the increased margin of error would cause the width of the confidence interval to become wider.

A chef at a restaurant uses 17 pounds of butter each day. About how many grams does the chef use each day?
answer
7711.07
Step-by-step explanation:
The chef uses 7,711.03 grams each day at a restaurant.
How to convert Pounds to Grams?The methodology to convert Pounds to Grams is relatively simple. To convert Pounds to Grams, you must multiply the unit by 453.59.
For example, if you have to convert 5 Pounds to Grams, you need to multiply 5 by 453.59.
A chef at a restaurant uses 17 pounds of butter each day.
We have to determine the number of grams the chef uses each day.
Since 1 pound (lb) is equal to 453.59 grams (g).
So 17 pounds = 453.59 × 17 = 7,711.03 grams
Thus, the chef uses 7,711.03 grams each day.

Step-by-step explanation:
The point-slope form of the equation of a line that passes through points (8, 4) and (0, 2) is y - 4 = (x – 8). What
is the slope-intercept form of the equation for this line?
O y = 1 x - 12
O y = -x-4
O y=+*+2
O y=x+6
Answer: y = x/4 + 2
Y equals one fourth x plus two.
Step-by-step explanation:
There seems to be a typo on answer choice c.
Slope intercept form is y= mx + b
m is the slope. b is the y-intercept.
The y-intercept is given here in the coordinate (0,2) It is +2
Slope is rise/run.
Rise: Difference in given y-values is 4-2 = 2.
Run: Difference in x-values is 8-0=8.
So the slope is 2/8 = 1/4
The equation is y = 1/4 x + 2

A line passes through the points (8, 1) and (6, 7). What is the slope?
Answer:
-3
Step-by-step explanation:
7-1=6
6-8=-2
A line connects the points (8, 1) and (6, 7). The angle is -3.
What is meant by slope?The slope or slope of a line is a number in mathematics that describes both the direction and slope of a line. Gradients are frequently represented by the letter m.There is no clear reason why the letter m is used for gradients, but it was first used in English by O'Brien (1844), who wrote the equation for a straight line as "y = mx + b."He is also depicted in Tod Hunter's (1888) work, where he wrote "y = mx + c."The slope is calculated by dividing the difference between two (arbitrary) points on a line by the ratio of vertical and horizontal change.Therefore,
Slope (m) = ΔY/ΔX
= 3/-1
= -3
The slope = -3
θ = arctan(ΔY/ΔX) + 180°
=1 08.43494882292°
ΔX = 6 – 8 = -2
ΔY = 7 – 1 = 6
Distance (d) = √ΔX2 + ΔY2 = √40 = 6.3245553203368
Equation of the line:
y = -3x + 25
When x = 0, y = 25
When y = 0, x = 8.3333333333333
Hence, A line connects the points (8, 1) and (6, 7). The angle is -3.
