Step-by-step explanation:
given
f(x) =3x² - x - 4
To obtain roots set f(x) = 0, that is
3x² - x - 4 = 0
To factor consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 3 × - 4 = - 12 and sum = - 1
The factors are + 3 and - 4
Use these factors to split the x- term
3x² + 3x - 4x - 4 = 0 ( factor the first/second and third/fourth terms )
3x(x + 1) - 4(x + 1) = 0 ← factor out (x + 1)
(x + 1)(3x - 4) = 0
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
3x - 4 = 0 ⇒ 3x = 4 ⇒ x =
The roots are x = - 1 and x =
By the list provided that would give option 1
Answer:
A.) JH = 1 in
B.) GH = 3/4 in
C.) m∠F = 62°
D.) m∠J = 118°
Step-by-step explanation:
In a parallelogram, opposite angles are congruent, adjacent angles are supplementary, and opposite sides are congruent.
A.) JH = FG = 1 in
B.) GH = FJ = 3/4 in
C.) m∠F = m∠H = 62°
D.) m∠J = m∠G = 180° -62° = 118°

Answer:
With a skewed distribution and data with outliers.
Step-by-step explanation:
There are three measures of central tendency.
- Mean: It is the average value of data and affected by presence of outliers.
- Median: It is the value that divides the data into two equal parts. It is a position based measure of tendency.
- Mode: It is the most frequent observation in the data.
- For a symmetrical distribution for continuous data, the mean, median, and mode are equal.
- For such case mean is a better measure of central tendency because it includes all of the data in the calculations.
- Median is the best measure of central tendency when the data is not symmetrical because the median is position based.
- Advantage of the median:
The median is not affected by outliers and skewed data as compared to the mean.
Thus, median likely to produce a better measure of central tendency than the mean with a skewed distribution and data with outliers.
Answer:
$262.50
Step-by-step explanation:
7 Months is approximately 30 weeks.
25 x 30 = $750
10% = $75
5% = $37.50
60% = (75x6) = $450
$450 + $37.50 = $487.50
$750 - $487.50 = $262.50
