Debbie estimated that a caterpillar was 4.5 cm long. Later, she found its actual length to be 4.8 cm. Find the percent error.
Answer:
Percent error = 6.25%
Step-by-step explanation:
Percentage error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
[tex] Percent \; error = \frac {experimental \;value - theoretical \; value}{ theoretical \;value} *100[/tex]
Given the following data;
Experimental value = 4.5cm
Theoretical value = 4.8cm
Substituting into the equation, we have;
[tex] Percent \; error = \frac {4.8 - 4.5 }{ 4.8} *100[/tex]
[tex] Percent \; error = \frac {0.3}{4.8} *100[/tex]
[tex] Percent \; error = 0.0625 *100[/tex]
Percent error = 6.25%

Which values are solutions of the inequality 5
Choose ALL that apply.
A8 B9 C13 D15 E20
Answer:
y<13
answer A and B because they both less than 13
Step-by-step explanation:
5 greater than y-8 ( if this is the inequality)
5>y-8
5+8>y
y<13
Answer:
Wait wait wait I don't think any of these are the answer because subtracting a negative means adding a positive so none of these work.
Step-by-step explanation:
Inequality: 5 > y - (-8)
(Using Solution A: )
5 > 8 - (-8)
5 > 8 + 8
5 > 16
(Using Solution B: )
5 > 9 - (-8)
5 > 9 + 8
5 > 17
(Using Solution C: )
5 > 13 - (-8)
5 > 13 + 8
5 > 21
(Using Solution D: )
5 > 15 - (-8)
5 > 15 + 8
5 > 23
(Using Solution E: )
5 > 20 - (-8)
5 > 20 + 8
5 > 28

Given f(x)= 7x-5. Find the value of f(8)
Answer: 52
Explanation:
You need to replace the x-values with 8 to solve this. So, the equation would look like this. f(8)= 7 x 8 - 5
7 times 8 is 56. 56 minus four is 52 which is your answer.
If you needed to graph this then it would look like this... (8, 52)
The 8 is in the input because it is the x-value (we replace x with 8) and 52 is output/range/y-value because it is the answer.
Suppose the average lifetime of a certain type of car battery is known to be 60 months. Consider conducting a two-sided test on it based on a sample of size 25 from a normal distribution with a population standard deviation of 4 months.a) If the true average lifetime is 62 months and ďˇ =0.01, what is the probability of a type II error
Answer:
0.53187998
Step-by-step explanation:
We are given;
Population mean; μ = 60
Sample size; n = 25
Population standard deviation; σ = 4
Significance level; α = 0.01
Let's define the hypothesis;
Null hypothesis;H0: μ = 60
Alternative hypothesis;Ha: μ ≠ 60
Z-score for a significance level of 0.01 from tables is z = 2.575
Since it's a 2 sided test, then;
Z-score at lower limit = -2.575
Z-score at upper limit = 2.575
We know that z-score formula is;
z = (x¯ - μ)/(σ/√n)
At lower limit;
-2.575 = (x¯ - 60)/(4/√25)
-2.575 × 0.8 = x¯ - 60
-2.06 = x¯ - 60
x¯ = 60 - 2.06
x¯ = 57.94
At upper-limit;
2.575 = (x¯ - 60)/(4/√25)
2.575 × 0.8 = x¯ - 60
2.06 = x¯ - 60
x¯ = 60 + 2.06
x¯ = 62.06
the probability of a type II error is expressed as:
β = P(57.94 < x¯ < 62.06)
If the true average lifetime is 62 months, then;
β = P((57.94 - 62)/(4/√25)) < z < (62.06 - 62)/(4/√25)
β = P(-5.08 < z < 0.08)
β = P(Z < 0.08) - P(Z < -5.08)
From z-distribution table attached, we have; P(Z < 0.08) = 0.53188
Also, from z-distribution calculator online, we have;
P(Z < -5.08) = 0.0000000189
Thus;
β = 0.53188 - 0.0000000189
β ≈ 0.53187998

assignment name: transformations
Answer:
K(1,0), L(2, 3), M(-1, 4), N(-2,1)
Step-by-step explanation:
Because the points are being flipped over the x-axis the y values remain the same, but the x values are multiplied by -1. Multiplying the values by -1 will switch a negative value positive and a positive value negative. This will correctly flip the points to the opposite side of the graph.

Explain the steps to solve for g in the equation −1/3g+5=2 .
Answer:
g = 9. I hope that I help my buddy out :)
Answer:
g=9
Step-by-step explanation:
Step 1: Subtract 5 from both sides.
-1/3g=5-5=2-5
-1/3g=-3

Tell whether the equation 5x + y = 0
represents a direct variation. If so, identify the
constant of variation.
Answer:
The equation 5x + y = 0 represents a direct variation
The constant of variation is k=-5
Step-by-step explanation:
We need to tell if the equation 5x+y=0 represents a direction variation or not.
The equation for direct variation is: [tex]\mathbf{y=kx}[/tex]
where k is constant of variation.
In the given equation:
[tex]5x+y=0\\y=-5x[/tex]
Comparing it with general equation for direct variation [tex]\mathbf{y=kx}[/tex] we get [tex]y=-5x[/tex] so equation represents direct variation.
Value of k is -5
So, the constant of variation is k=-5
