If u r getting it for 14% off, then u r paying 86%

so the reduced price can be represented by 0.86x

or
x - 0.14x

Answer: The reduced price can be represented by 86%.

Step-by-step explanation:

Let the original price of computer be 'x'.

Rate of price reduction = 14%

Amount of reduction would be

\dfrac{14}{100}\times x\\\\=0.14x

So, Reduced price of a computer would be

x-0.14x\\\\=0.86x

Hence, the reduced price can be represented by 86%.

Suppose the population standard deviation is σ = 5 , an SRS of n = 100 is obtained, and the confidence level is chosen to be 98%
beks73 [17]

Answer:

1.165.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.98}{2} = 0.01

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.01 = 0.99, so z = 2.33

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

In this problem, we have that:

\sigma = 5, n = 100. So

M = z*\frac{\sigma}{\sqrt{n}}

M = 2.33*\frac{5}{\sqrt{100}} = 1.165

So the correct answer is:

1.165.

Answer:

90⁰

Step-by-step explanation:

y=cosx

y'= -sinx

eqñ of tangent is y=-x

slope of tangent =-1

we know...

slope of tangent = y' or derivative of y

-sin x = -1

sin x= 1

x = 90⁰

Anestetic [448]
First we distribute \frac{1}{5} into n and -\frac{1}{7}.

\frac{1}{5} * n =  \frac{1}{5} n
\frac{1}{5}  *  -\frac{1}{7}  = - \frac{1}{35}

That makes the left side of the equation 

\frac{1}{5} n -  \frac{1}{35} =  \frac{1}{6} n

Now we subtract \frac{1}{5}n from \frac{1}{6} n, which makes \frac{1}{30}

Now the equation is 

-\frac{1}{35} =  -\frac{1}{30n}

Our goal is to isolate n, so we both sides by 30

30* -\frac{1}{35} = - \frac{1}{30}n * 30 

That will make the equation 

- \frac{30}{35} = -n

We multiply -1 on both sides of the equation:

\frac{30}{35} = n

Finally we simplify \frac{30}{35}, which makes \frac{6}{7}

So the answer is n =  \frac{6}{7}

Question 10 of 15
AysviL [449]

Answer:

If Angelo can Mow his lawn in 2/3 of an hour or 40 minutes, it means that after 1/2 or 30 minutes 75% of the lawn will be mowed, this is because if he can mow the lawn in 40 and we want to know how much he can mow in 30 minutes this gives us the fraction 30/40 which is also equal to 3/4 or 75%. meaning that the correct picture is the one that shows that 3/4 of the lawn is mowed
