Answer:
x = 12
Step-by-step explanation:
10x = 120 original equation
10x/10 = 120/10 divide both sides by 10
x = 12 simplify
Check work:
10(12) = 120
120 = 120 (true)
Answer:
1877 computer users
Step-by-step explanation:
We have that for 95% of confident, the value of z has a value of 1.96 (attached table about it), they also mention the margin of error (E) that is 10 and finally the standard deviation (sd) that has a value of 221.
We apply the following formula:
n = [z * sd / E] ^ 2
replacing:
n = [1.96 * 221/10] ^ 2
n = 1876.27
that is, the minimum sample size is 1877
Answer:
Linear Decreasing
Step-by-step explanation:
Exponential graphs are curved, but this line is straight, so it's linear. It's decreasing since the graph moves from left to right, and as you can see, the line starts from the left tall but gradually goes lower as it goes towards the right.
Answer: Yes
Step-by-step explanation:
Answer:
No I dont agree with Mai. As both the slug and snail are moving with constant speed.
Step-by-step explanation:
Given that:
A slug travels 3 centimeters in 3 seconds.
Speed of slug = distance/ time = 3/3 = 1 cms^-1
A slug travels 3 centimeters in 3 seconds.
Speed of snail = distance/ time = 6/6 = 1 cms^-1
Hence both have constant speeds only the time span for snail is increased which gives more distance it doesn't means that it had covered more distance.
i hope it will help you!
