How do we find the quadratic equation in standard form with the given roots of -1/3, 5?

I think this is the answer. Because it doesn’t mention a leading coefficient but it’s a quadratic function so it would be
1(x-1/3)(x-5) and that should be your answer. The simplified version is down below

1.0649 to the nearest thousandths is 1.065

You could get this by finding where the thousandths place is, which is the third number.
Now, look at the number to the right. 
If it's 5 or higher, round up. 
If it's 4 or lower, round down.

Since it is 9, we round up.
The 4 turns into a 5.

So, 1.065

Hope I helped!

Does anybody have any tips for calculating slopes in Algebra 1???
I am Lyosha [343]

Answer:

The equations are really hard, so if you can find a slope interpreter or something that might be helpful.

I find it easier to just count the up and across.

The base of a right circular cylinder has a diameter of 5.00 inches. Sally measured the circumference of the base cylinder and r
LUCKY_DIMON [66]

Answer:

The percent of error in her measurement is 1.3%

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=\pi D

where

D is the diameter

we have

D=5\ in

assume

\pi=3.14

substitute

C=(3.14)(5)=15.7\ in ----> This value represent the 100% (theoretical value)

Find the difference between the theoretical value and the measured value

15.7-15.5=0.2\ in

Find the percentage by proportion

15.7/100=0.2/x\\ x=100*0.2/15.7\\ x=1.3\%

Last year, 50% of MNM. Inc. employees were female. It is believed that there has been a reduction in the percentage of females i
Serhud [2]

Answer:

We conclude that there has been a significant reduction in the proportion of females.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 400

p = 50% = 0.5

Alpha, α = 0.05

Number of women, x = 118

First, we design the null and the alternate hypothesis  

H_{0}: p = 0.50\\H_A: p < 0.50

This is a one-tailed test.  

Formula:

\hat{p} = \dfrac{x}{n} = \dfrac{118}{400} = 0.45

z = \dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}

Putting the values, we get,

z = \displaystyle\frac{0.45-0.50}{\sqrt{\frac{0.50(1-0.50)}{400}}} = -2

Now, we calculate the critical value.

Now, z_{critical} \text{ at 0.05 level of significance } = -1.645

Since the calculated z-statistic is less than the critical value, we fail to accept the null hypothesis and reject it. We accept the alternate hypothesis.

Thus, there has been a significant reduction in the proportion of females.
