a , [tex]5\frac{9}{14}[/tex]
b,[tex]7\frac{1}{2}[/tex]
Answer:
A) 5 9/14
B) 7 1/2
Step-by-step explanation:
Question A asks what is 4 1/7 + 1 1/2
First turn the problem into improper fraction for it to be easier to calculate.
29/7 + 3/2
Now we have to find the denominator(bottom number)
We have 7 and 2 as our denominators. So we need to find out the lcm(least common factor)
For 7 and 2 the lcm is 14
So far we have:
29/7 + 3/2 = ?/14 + ?/14 = ?
Now we need to find the numerator(The top number). That fills in the ? over the two 14's.
To find the numerator we need to mutiply.
29/7 + 3/2 = ?/14 + ?/14 = ?
7 × ? = 14 the answer is 2 so then we multiply the top also with 2. So 29 × 2 = 58.
29/7 + 3/2 = 58/14 + ?/14 = ?
Now we have figured out one of the ?
We do the same thing for the other one
2 × ? = 14 answer is 7 so we also multiply the top with 7. 3 × 7 = 21.
29/7 + 3/2 = 58/14 + 21/14 = ?
Now we have to solve this:
58/14 + 21/14 = ?
The denominator is 14 because both of them are 14.
The top we need to add together so 58+21= 79
Now our answer is:
79/14
If we simplify it(by turning into improper fraction):
5 9/14
B) question is 4 1/2 ÷ 3/5
First we turn it into inproper fraction
9/2 ÷ 3/5
Since it is divsion we have to flip the second fraction which is 3/5 into 5/3, and turn the ÷ symbol into ×
9/2 × 5/3
Now we multiply across
9×5 = 45
2×3 = 6
answer: 45/6
Now if we simplify:
7 1/2

A very simple question for trigonometry! So lets say I want to use a formula for example csc = 1/sin a. Would that still apply if instead of sin a it is - sin a? If not, can I still use this formula is sin a is negative? Thanks!
Answers
Answer:
Step-by-step explanation:
csc = 1/sin a would be OK if you'd insert the argument 'a:'
csc a = 1/sin a is an identity (a relationship that is always true).
If you write csc a = 1 / (-sin a) you are creating a conditional equation which may be true for some values of a but not for all.

please hurry write a vector equation of a line that passes through p(-4,12) and is parallel to q=(14,-8)
Answers
The line containing the vector q can be obtained by scaling q by an arbitrary scalar t. To make this line pass through the point p, translate this line by a vector p pointing from the origin to p.
So the line we want has equation
r(t) = qt + p = (14, -8)t + (-4, 12) = (14t - 4, 12-8t)
where t is any real number.
The Vector Equation which passes through point p(-4, 12) and parallel to q(14, -8) is r(t) = (14t-4, 12-8t).
What is a vector equation?A vector equation is an equation involving a linear combination of vectors with possibly unknown coefficients.
Here, the line containing the vector q can be obtained by scaling q by an arbitrary scalar t. To make this line pass through the point p, translate this line by a vector p pointing from the origin to p.
r(t) = q*t + p
r(t) = (14, -8)t + (-4, 12)
r(t) = (14t - 4, 12-8t)
where t is any real number
Thus, the Vector Equation which passes through point p(-4, 12) and parallel to q(14, -8) is r(t) = (14t-4, 12-8t).

Answers
Answer:
Reflecting over y = -1 line:
A'(8, -10)
B'(10, -8)
C'(2, -4)
Reflecting over y = -7 line:
A''(8, -4)
B'(10, -6)
C''(2, -10)
Step-by-step explanation:
Reflect the given preimage over y=−1 followed
by y=−7. Find the new coordinates. What one transformation is this double reflection the same as? (Note: when you are reflecting over a y= line, the x-values of the preimage will remain the same and you will be changing the y-values)
The coordinates of the preimage are:
A(8,8)
B(10,6)
C(2,2)
Answer: Reflecting over y = -1:
If a point is reflected over a y line, the x values remain the same while the y values change.
For point A(8, 8): The y distance between the y = - 1 line and point A is 9 units. (8- (-1)). If point A is reflected, the y value would be 9 units below the y = -1 line, i.e the new y coordinate would be at -10 (-1-9)
The new coordinate is at A'(8, -10)
For point B(10, 6): The y distance between the y = - 1 line and point B is 7 units. (6- (-1)). If point B is reflected, the y value would be 7 units below the y = -1 line, i.e the new y coordinate would be at -8 (-1-7)
The new coordinate is at B'(10, -8)
For point C(2, 2): The y distance between the y = - 1 line and point C is 3 units. (2- (-1)). If point C is reflected, the y value would be 3 units below the y = -1 line, i.e the new y coordinate would be at -4 (-1-3)
The new coordinate is at C'(2, -4)
Reflecting over y = -7 line:
For point A'(8, -10): The y distance between the y = - 7 line and point A' is 3 units. (-7- (-10)). If point A' is reflected, the y value would be 3 units above the y = -7 line, i.e the new y coordinate would be at -4 (-7+3)
The new coordinate is at A''(8, -4)
For point B'(10, -8): The y distance between the y = - 7 line and point B' is 1 units. (-7- (-8)). If point B' is reflected, the y value would be 1 units above the y = -7 line, i.e the new y coordinate would be at -6 (-7 + 1)
The new coordinate is at B'(10, -6)
For point C'(2, -4): The y distance between the y = - 7 line and point C' is 3 units. (-4- (-7)). If point C' is reflected, the y value would be 3 units below the y = -7 line, i.e the new y coordinate would be at -10 (-7-3)
The new coordinate is at C''(2, -10)
We can also see that h= −7−(−1)=−6. We know that two reflections is the same as a translation of 2h units down. So 2(−6) is a translation of −12 units down.

Step-by-step explanation:
5. A biologist is measuring the lengths of frogs in a certain location. The lengths
of the frogs have a mean of 7.4 centimeters and a standard deviation of 0.8
centimeters. What is the probability that a randomly selected frog will measure
between 5.8 cm and 8.2 cm?
Using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean
σ is the population standard deviation.
z1 = (x-μ)/σ
x is the raw score = 5.8cm
μ is the population mean = 7.4cm
σ is the population standard deviation. = 0.8cm
= 5.8 - 7.4/0.8
= -2
Using a z score table to find the probability of -2
P(z = -2) = 0.02275
z2 = (x-μ)/σ,
x is the raw score = 8.2cm
μ is the population mean = 7.4cm
σ is the population standard deviation. = 0.8cm
z = 8.2 - 7.4/0.8
z = 1
Using the Z-Table to find the probability
P(z = 1) = 0.84134
Hence, the probability that a randomly selected frog will measure between 5.8 cm and 8.2 cm is calculated as:
0.84134 - 0.02275 = 0.81859
6. Using the data from question #5, what is the probability that a randomly
selected frog will measure less than 6.6 cm?
Your answer
Using z score formula
z = (x-μ)/σ, where
x is the raw score = 6.6cm
μ is the population mean = 7.4cm
σ is the population standard deviation. = 0.8cm
z1 = (x-μ)/σ
= 6.6 - 7.4/0.8
= -1
Using the Z-Table to find the probability a randomly selected frog will measure less than 6.6 cm
P(x<6.6) = 0.15866
7. Using the data from #5, if 100 frogs are measured, how many of them would you predict to measure longer than 8.2 cm?
z = (x-μ)/σ,
x is the raw score = 8.2cm
μ is the population mean = 7.4cm
σ is the population standard deviation. = 0.8cm
z = 8.2 - 7.4/0.8
z = 1
Using the Z-Table to find the probability
P(x<8.2) = 0.84134
To find the probability of frogs that would be longer than 8.2cm
P(x>8.2) = 1 - P(x<8.2) = 0.15866
To calculate the number would be predicted to measure longer than 8.2 cm is :
0.15866 × 100 = 15.866% is longer than 8.2cm
Therefore,
15.866% × 100 frogs = 15.866 frogs.
