Hello there! :)
Answer:
y = -4x.
Step-by-step explanation:
Begin by finding the slope of the line using the slope formula:
Plug in two points on the graph. We can use the points (-1, 4) and (0, 0):
Simplify:
m = -4.
Therefore, the equation of this line in slope-intercept form (y = mx + b) is:
y = -4x.
Answer:
Your answer would be number 4, "A and D"
Step-by-step explanation:
I already know that if you multiply a number by less than 1 it will give a product less than the original number so that makes B and C not the correct answer leaving a and d
I hope this helps :D
Answer:
The sample size required is 910.
Step-by-step explanation:
The confidence interval for population proportion is:
The margin of error is:
Given:
The critical value of <em>z</em> for 90% confidence level is:
*Use a standard normal table.
Compute the sample size required as follows:
Thus, the sample size required is 910.
Answer:
B
Step-by-step explanation:
X must not be equal to -6, -1, 1 or 3
Answer:
b. Every 24 minutes
Step-by-step explanation:
A neon sign blinks every 6 minutes, and another sign blinks every 8 minutes.
The first step is to:
Find and list multiples of each time each neon sign blinks.
This means, we find the Multiples of 6 and 8
Multiples of 6:
6, 12, 18, 24, 30, 36
Multiples of 8:
8, 16, 24, 32, 40
The first and common multiple of 6 and 8.
Therefore, the Least common multiple [LCM(6, 8) ] = 24
Hence, they often blink at the same time every 24 minutes.
Therefore, option b.Every 24 minutes is correct.
