How many solutions does the system have? y=−2x+1y=−2x2+1?

Flura [38]

Set the equations to equal each other:
-2x²+1=-2x+1

Solve for x:

-2x²+1=-2x+1
-2x²+2x+1=-2x+2x+1
-2x+2x+1-1=1-1
-2x²+2x=0
2x (-x+1)=0

2x=0 and -x+1=0
2/2x=0/2 -x+x+1=0+x
x=0 1=x

There are two solutions, x=0,1

You're given the conversion formula of 1 yard = 3 feet and 1 foot = 12 inches so let's use that.

For red you're given three yards so because 1 yard = 3 feet, then you have
3 feet + 3 feet + 3 feet = 9 feet ( or 3ft * 3)
Now, to get inches, you multiply 9 by 12 to get 108 inches.
Since each bow requires 6 inches of ribbon you divide 108 by 6.
- Number of red bows: 18
- Inches of ribbon: 108

Yellow
Given: 54 inches
to convert to feet, you divide by 12 : 54/12 = 4.5 and to find yards you divide by 3: 4.5/3 = 1.5
to find the number of bows you divide 54 by 6: 9 bows
-Number of yellow bows: 9
-Yards of yellow ribbon: 1.5

Blue
Given: 24 bows
Because there's 6 inches for every bow 24*6 = 144 inches of ribbon
Convert to yards: 144/12 = 12 feet / 3 ft = 4 yards
-Inches of blue ribbon:144
-Yards of blue ribbon: 4

A simple random sample of 25,000 individuals are surveyed in order to determine the prevalence of individuals that contracted th

Neko [114]

Answer:

The prevalence of flu for the past year, as indicated from the survey participants, was of 17%.

Step-by-step explanation:

Given the survey, the prevalence of the flu, as a percentage, is given by:

Number of individuals diagnosed with flu, multiplied by 100, and divided by the size of the sample.

In this question, we have that:

Sample of 25,000, and 4,250 of those had been diagnosed with the flu at some point in the past year. So, the prevalence of the flu is given by:

$\frac{4250*100}{25000} = 17$

The prevalence of flu for the past year, as indicated from the survey participants, was of 17%.

I will give you 50 point please help and get. it right

6)The experimental probability is 39%.(39/100(100)).

7) The theoretical probability is theoretical. This is when something should happen without taking external forces into account. Experimental probability is taking the external forces into account which is why the probability is not as clean cut.

The theoretical probability should be 33%.
The experimental probability is actually 39%.
