Answer: It’s C again lol
Step-by-step explanation:
Use the quadratic formula to solve for x. 5x² + 4x=4 Round your answer to the nearest hundredth. If there is more than one solution, separate them with commas.
1/2(x+2)+7=3x+(-32)
explained pls
Answer:
x is equal to 16
Step-by-step explanation:
Combine multiplied terms into a single fraction
Multiply by 1
Subtract 7 from both sides of the equation
Simplify it
Subtract 3 from both sides of the equation
Simplify
Multiply all terms by the same value to eliminate fraction denominators
Simplify
Subtract 2 from both sides of the equation
Simplify
Divide both sides of the equation by the same term
Simplify!
That's it!

Step-by-step explanation:
there are eight pints in a gallon, and since theres two gallons, that mean theres 16 pints. 16 divided by 14.24 is 1.12
what is the equation to the point slope form?
Answer:
The point slope form of a line is
y-y1 = m(x-x1) where m is the slope and ( x1,y1) is a point on the line
Step-by-step explanation:
The standard form for a line is
Ax + By +C =0
The slope intercept form for a line is
y = mx+b where m is the slope and b is the y intercept
The point slope form of a line is
y-y1 = m(x-x1) where m is the slope and ( x1,y1) is a point on the line
According to the 2018 general social survey (gss), 60% of all u. s. households have at least one pet. a veterinarian in ann arbor decided to conduct a survey to assess if over 60% of all ann arbor households have at least one pet. a 10% significance level was selected to be used. the random sample of 280 ann arbor households, resulted in 182 stating they currently have at least one pet. these results are turned over to you to perform the appropriate test. 1) state the appropriate hypotheses to be tested with a complete definition of the parameter of interest. (the significance level has been selected to be 10%). 2) check the necessary assumption(s) (you may assume that the selected sample is a random sample). 3) perform the appropriate test (include all supporting computations for the test statistic and p-value) 4) give your decision and provide a conclusion in context. your answer needs to be organized well and use labels for your steps 1, 2, 3, and 4. question 8 answer no answer entered.
Step-by-step explanation:
1. the claim here is that over 60 percents of the households living in ann harbor have pets.
null hypothesis;
h0: p≤0.60
alternative:
h1: p>0.60
2.
n is the size of the sample = 280
n(p) = 280 x 0.60 = 168 greater than 10
n(1-p) = 280(1-0.6) = 280 x 0.4 = 112 greater than 10
we use the normal dist since each of the above are greater than 10
3. n = 280
x = 182
x/n = 182/280
= 0.65
we get the test statistic z
z = [tex]\frac{0.65-0.6}{\sqrt{0.6*(1-0.6)/280} }[/tex]
= [tex]\frac{0.05}{\sqrt{0.000857} }[/tex]
=[tex]\frac{0.05}{0.02927}[/tex]
≈ [tex]1.71[/tex]
we get the p value = 1-p(z<1.71)
= 1-.9562
this gives 0.0438
4. we can see that 0.0438 < 0.10
so we conclude that over 60% of these households have at least one pet since we rejected h0.

Jose deposits S300 into an account that pays simple interest at a rate of 6% per year. How much interest will he be paid in the first 3 years?
Answer:
$54
Step-by-step explanation:
300 times 0.06 times 3
0.06 times 3 = 0.18
300 times 0.18 = 54
The simple interest is $54
Answer:
$54
Step-by-step explanation:
A = P(1 + rt)
300(1 + (0.06 × 3)) = 354

Given:
A composed figure of a rectangle, semicircle and another semicircle removed.
To find:
The area of the given figure.
Solution:
From the given figure it is clear that the diameter of semicircle and removed semicircle are same, i.e. 8 cm.
Since the diameter of semicircle are equal, therefore their area is also equal.
The area of the given figure is:
A = Area of the rectangle - Area of removed semi circle + Area of semicircle
A = Area of the rectangle - Area of semicircle + Area of semicircle
A = Area of the rectangle
We know that, the area of a rectangle is
[tex]A=length\times width[/tex]
The length of the rectangle is 14 units and width is 8 units. So, the area of composed figure is
[tex]A=14\times 8[/tex]
[tex]A=112[/tex]
Therefore, the area of the combined figure is 112 sq. units.
