Answer:
the student may have made the mistake because the student was paying more attention to how many blocks he was filling in rather than how much he was filling in.
to solve the problem correctly you would just switch the decimals
0.8 > 0.08
0.8 should have 80 blocks filled
0.08 should have 8 blocks filled

Answer:
X= 67.25
Step-by-step explanation:
4x-35=234
Add 35 to both sides
4x= 269
Divide both sides by 4
X= 67.25
Answer:
x = 67,25
Step-by-step explanation:
Here it is given that,
x is an unknown to know. Since we are intelligent students, we will bring the unknowns to the left limb, and the numbers known in the right limb.[tex]\:[/tex]
We can write this matematically as,
[tex]\rightarrow 4x - 35 =234[/tex]
Move the constant to the right,
[tex]\rightarrow 4x =234 + 35[/tex]
Add the numbers,
[tex]\rightarrow 4x =269[/tex]
Divide both sides of the equation by 4,
[tex]\rightarrow x =\frac{269}{4}[/tex]
We determine the value of x,
[tex]\rightarrow \underline {x=67,25}[/tex]

Question 3
Write the rational number as a decimal.
Answers
Answer: -2.2
Step-by-step explanation:
-10 is the most possible that can be divided by 5, resulting in -2.
The leftover 1 is divided by 5, resulting in .2.
The decimal ends up being -2.2.
Answer:
-2.2 or -1.2
Step-by-step explanation:
When you want to write a decimal as a fraction, you simply divide the numerator with the denominator. So when you divide -11 by five that would be a -2.2. Or if it is -1 1/5 the answer would be -1.2. I cant really tell what that number is.
A textbook company states that the average time a student needs to take a quiz from its book is 30 minutes with a standard deviation of 3 minutes. A teacher using the book is not sure that this is correct for her classes and wants to check. She collects data on 10 random students and finds that the average time to take the quiz was only 25 minutes. As a result, the teacher performs a two-tailed hypothesis test with a significance level of 5%. Which conclusion is valid based on the results of the test
Answers
Answer:
We conclude that her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company states.
Step-by-step explanation:
We are given;
Population mean; μ = 30 minutes
Population standard deviation; σ = 3 minutes
Sample size; n = 10
Sample mean; x¯ = 25
Significance level = 5% = 0.05
Let's define the hypotheses;
Null hypothesis; H0: μ = 30
Alternative hypothesis: Ha: μ ≠ 30
Let's find the test statistic;
z = (x¯ - μ)/(σ/√n)
z = (25 - 30)/(3/√10)
z = -5.27
From online p-value from z-score calculator attached using, z = -5.27, significance level = 0.05, two tailed hypothesis, we have;
p < 0.00001
This is less than the significance level, and so we will reject the null hypothesis and conclude that Her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company stated.
Answer:
A. Her students, on average, do not take 30 minutes on the quiz, contrary to what the textbook company stated.

A. (5, 7) and (-4,-2)
B. (1, 3) and (1, -10)
Answers
Answer:
Step-by-step explanation:
to find the slope of a line that passes for two given points we can use this formula (y2-y1)/(x2-x1). x and y inidcate the coordinates of the two points.
A (-2-7)/(-4-5) = (-9)/-9 = 1 (m is positive)
B (-10-3)/(1-1)) = the denominator is equal to zero, so the division is impossibile. This mean that m is undefined and the line is parallel to y axis
A small airplane is approaching a stationary crowd at 100 meters per second. The engine of the plane is emitting a sound of 485 Hz. What is the apparent frequency as it approaches the crowd?
Answers
Answer:
695.87 Hz
Step-by-step explanation:
Using the equation for Doppler shift, the frequency of the apparent sound is f' = f(v ± v')/(v ± v") where f = frequency of sound emitted by the plane's engine = 485 Hz, v = speed of sound in air = 330 m/s, v' = speed of crowd(detector) = 0 m/s (since the crowd are stationary) and v" = speed of plane(source) = 100 m/s
So, f' = f(v ± v')/(v ± v")
f' = f(v ± 0)/(v ± v")
f' = fv/(v ± v")
Since the source moves towards the detector, we use a minus a minus sign in the denominator to get a shift upwards in frequency since a shift upwards means the objects are moving closer to each other.
So,
f' = fv/(v - v")
Substituting the values of the variables into the equation, we have
f' = 485 Hz × 330 m/s/(330 m/s - 100 m/s)
f' = 160050 Hzm/s ÷ 230 m/s
f' = 695.87 Hz

Calculate distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
(1) with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (6, 8)
d = [tex]\sqrt{6-0)^2+(8-0)^2}[/tex]
= √(6² + 8²)
= √ (36 + 64)
= √ 100
= 10 → B
(2)
Using (x₁, y₁ ) = (- 5, 3) and (x₂, y₂ ) = (3, 15)
d = √ (3 + 5)² + (15 - 3)²
= √ 8² + 12²
= √ 64 + 144
= √ 208
