You can convert each as a percentage or convert them all out of 5.

4/20 simplified is 1/5.

1/5 in percent is 20%

So you have 20%, 25%, and 20%

In decimal, you have:

.20, .25, .20

Determine whether the given value is a solution of the equation.<br> 7w = 73; w = 10
kipiarov [429]

Step-by-step explanation:

When w=10, 7w=7×10=70

But the given value of 7w is 73.

So, the given value is not a solution of the equation.

How do you find velocity of a dt graph
givi [52]
Answer: to find velocity, simply put (d2-d1) over (t2-t1) or d/t.

Explanation: To find velocity, divide the change in distance by the change in time. On a graph, pick two points and find the slope of one portion of the line.
Why the slope?
Well this is like your normal x vs. y graph. X being the time and y being your distance.
To find the slope for this, it uses the same formula: (Y2-y1) / (x2-x1)

Hope this helps!!!
BTW, this is physics.

The mean length of long-distance telephone calls placed with a particular phone company was known to be 7.8 min under an old rat
yarga [219]

Answer:

H0: μ = 7.8

Ha: μ > 7.8

Step-by-step explanation:

The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.

For the case above;

Let μ represent the true mean length of long-distance calls after the rate reduction

The null hypothesis is that true mean length of long-distance calls after the rate reduction is the same and equal to 7.8 minutes

H0: μ = 7.8

The alternative hypothesis is that the true mean length of long-distance calls after the rate reduction have increased that is greater than 7.8 minutes

Ha: μ > 7.8

The area of the kite is 20ft squared. What is the value of y? Explain.
mylen [45]

Solution

Note: Area of Kite

From the question we have

\begin{gathered} Area=\frac{1}{2}\times10\times2y \\  \\ 20=10y \\  \\ y=2 \end{gathered}

Therefore, y = 2
