Answer:
(- 1, 5 )
Step-by-step explanation:
Using the method of substitution.
Given the 2 equations
3x + 2y = 7 → (1)
x - 4y = - 21 → (2)
Rearrange (2) expressing x in terms of y by adding 4y to both sides.
x = 4y - 21 → (3)
Substitute x = 4y - 21 into (1)
3(4y - 21) + 2y = 7 ← distribute and simplify left side
12y - 63 + 2y = 7
14y - 63 = 7 ( add 63 to both sides )
14y = 70 ( divide both sides by 14 )
y = 5
Substitute y = 5 into (3)
x = (4 × 5) - 21 = 20 - 21 = - 1
Solution is (- 1, 5 )
Answer:
$1,823.2
Step-by-step explanation:
Simple interest is calculated using the formula
I = P X R X T
where I is the interest amount
P is the principal amount: 45,580.
R is the interest rate which is 4 %, or 0.04%
T is time, One year.
I = $45,580 x 0.04 x 1
I = $1,823.2 x 1
I = $1,823.2
Answer:
Option D is correct.
Bimodal (Having two modes)
Step-by-step explanation:
- Symmetric distribution is a situation in which the values of variables occur at regular frequencies, and the mean, median and mode occur at the same point.
- In a negatively skewed distribution, the mean is usually less than the median because the few low scores tend to shift the mean to the left.
- In a positively skewed distribution, the mode is always less than the mean and median.
- A bimodal distribution is a continuous probability distribution with two different modes, that is, two different values with the highest and equal frequencies.

Answer: it might be 8
Step-by-step explanation: Write a distance formula: x^2 - x^1
substituted -3.8, 4.2 into x^2 - x^1 and u will get 4.2 + 3.8 and u will calculate and it gets 8
I hope its right
