Please help ASAP: X-1/2=3/4
Answer:
x = 5/4 OR 1 1/4
Answer:
x = 5/4 or 1 1/4
Step-by-step explanation:
X-1/2=3/4
Add 1/2 to each side
X-1/2+1/2=3/4+1/2
x = 3/4 +1/2
Get a common denominator
x = 3/4 + 2/4
x = 5/4
x = 1 1/4

units digit in (126^2)
Answer:
The unit digit of (126²) is 6
Answer:
That would be 6.
Step-by-step explanation:
Here it is.
The measures of the angles of a triangle are shown in the figure below. Solve for x.
Answer: 27°
Step-by-step explanation: Here, we're asked to find the missing angle measure in the triangle shown which is represented by the variable x.
To find the value of x, remember that the sum of the
measures of the angles in a triangle is 180°
So we can setup the equation 63 + 90 + x = 180.
Remember that a box indicates a 90° angle.
Now to solve for x, let's first simplify on the left side of the equation.
63 + 90 is 153 so we have 153 + x = 180.
Now to get x by itself, we subtract 153 from both sides of the equation.
On the left side of the equation, 153 - 153 cancels out and we have x
and on the right side of the equation, 180 - 153 is 27.
This means that the missing angle in the triangle is 27°.

A group of researchers was interested in the effect of music on the behavior of dogs. Specifcally, they wanted to
measure the effect of classical music on sleepiness as an indication of dogs' mental relaxation. They conducted
the following study on a group of 400 Jack Russell Terriers.
Every day for 4 months, the researchers would play Beethoven's Moonlight Sonata for 1 hour occurring
randomly between 9 a.m. and 12 p.m. During the entire 3 hours observers would record the times in which
each dog was sleeping. By the end of the 4 months, the researchers calculated and compared the percentage of
time each dog spent sleeping during each of two conditions: while the music was playing and while it wasn't
Is the study appropriate for the statistical questions it's supposed to answer?
Answer:
Step-by-step explanation:
The first part of the question would be: B) Experiment
The second part would be: C) No, because the sample the study used isn't representative of all dogs.
The independent variable is a variable that represents a quantity being manipulated in an experiment, the control group will be the group that did not hear the music, and the experimental group the group that heard the song.
What is Independent variable?An independent variable is a variable that represents a quantity being manipulated in an experiment.
xxx is often the variable used to represent the independent variable in an equation.
Dependent variables
A dependent variable represents a quantity whose value depends on how the independent variable is manipulated.
yyy is often the variable used to represent the dependent variable in an equation.
Confounding variable
It is a variable that influences both the dependent variable and the independent variable, causing a spurious association. The confounding variable is a causal concept and as such cannot be described in terms of correlations or associations.
With this information, we can conclude that, The control group are people who have not heard the music, the experimental group are those who heard the music, and the hypothesis is that music can change people's heart rate.

Instead I’d using the values 1,2,3,4,5,6 on dice, suppose a pair of dice have the following 1,2,2,3,3,4 on one die and 1,3,4,5,6.8 on the other.find the probability of rolling a sum of 12
Answer:1/24
Step-by-step explanation:
Since the first die has 4 distinct numbers, and second has 6 distinct numbers, so total number of combinations possible = 4 × 6 = 24
Now, the number of chances where we get the rolling sum as 12 is only one. (
Therefore, the probability of getting sum 12 is 1/24

Answer:
129 degrees
Step-by-step explanation:
One circle is 360 degrees, so add up all the degrees, including x:
35 + 55 + 141 + x = 360
231 + x = 360
x = 360 - 231
x = 129 degrees

What is the solution of this linear equation system? y = 3x-2 y-2 = x
Answer:
(2,4)
Step-by-step explanation:
Replace all occurrences of y with 3 x − 2 in each equation.
3x - 4 = x
y= 3x -2
Solve for x in the first equation.
x = 2
y = 3x - 2
Replace all occurrences of x with 2 in the equation.
y = 4
x= 2
The solution to the system is the complete set of ordered pairs that are valid solutions.

Ming traveled to the town hall and back. The trip there took two hours and the trip back took three hours. She averaged 10 mph faster on the trip there than on the return trip. Find Ming's average speed on the outbound trip.
Answer:30mph
Step-by-step explanation:
We know that the ratio must be 2:3. We know that 30 is 10 more than 20, which also fits into the ratio, so 30mph is the answer.

£2,300 is invested for 4 years at 5% per year simple interest work out the total interest
Answer:
£460
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 2300 × 0.05 × 4 = 460
I = £ 460.00
The simple interest accumulated
on a principal of £ 2,300.00
at a rate of 5% per year
for 4 years is £ 460.00.
