<span>y = 0</span><span> for the </span>x-intercept, so<span>
2х - 5*0 = 60
2x = 60
x = 60/2 = 30
(30, 0)
</span><span>x = 0</span><span> for the </span>y<span>-intercept, so:</span>
2*0 - 5x = 60
-5x = 60
5x = -60
x = -30/5 = -12
(0, -12)
Answer is a) (0, -12)(30, 0)
Answer:
-y² - 4y - 6
Step-by-step explanation:
Step 1: Write expression
5y² - 6y - 11 - 6y² + 2y + 5
Step 2: Combine like terms (y²)
-y² - 6y - 11 + 2y + 5
Step 3: Combine like terms (y)
-y² - 4y - 11 + 5
Step 4: Combine like terms (constants)
-y² - 4y - 6
A) Variance = 10.24
B) Standard Deviation = 3.2
One of the measurements of dispersion is the standard deviation, which is exclusively used for quantitative data. It aids in determining if the data's mean is a suitable measurement to reflect the core value.

∑fd = -136
∑fd² = 552

Standard Deviation = 

√4.35 - √1.15
Standard Deviation = 3.2
(SD)² = (3.2)² = 10.24
Variance = 10.24
