A competitive cliff diver jumps into
water 81 feet below. The distance d that the diver falls
in t seconds is given by the equation d = 16t^2. How
long does it take the diver to hit the water?
Answers
Answer:
2.25 seconds
Step-by-step explanation
[tex]d=16t^{2}[/tex]
[tex]d=81 feet\\t=?[/tex]
Because you know what distance equals you can plug it into the equation
[tex]81=16t^{2}[/tex]
From there you can solve by dividing the 16 over and then square rooting.
[tex]\frac{81}{16}=t^{2}[/tex]
[tex]5.0625=t^{2}[/tex]
You take the square-root to get rid of [tex]t^{2}[/tex]
[tex]\sqrt{5.0625} =\sqrt{t}^{2}[/tex]
[tex]t=2.25[/tex]

(3 tan 45°)(4 sin 60°)-(2 cos 30°)(3 sin 30°)
Answers
Answer:
[tex]9\,\sin(60^\circ)[/tex], which is equal to [tex]\displaystyle \frac{9\sqrt{3}}{2}[/tex].
Step-by-step explanation:
An angle of [tex]45^\circ[/tex] corresponds to an isosceles right triangle: the length of the two legs (adjacent and opposite) would be equal. Accordingly:
[tex]\displaystyle \tan(45^\circ) = \frac{\text{Opposite Leg}}{\text{Adjacent Leg}} = 1[/tex].
Let [tex]A[/tex] denote the measure of an angle. Double-angle identity for sine:
[tex]2\, \sin(A) \cdot \cos(A) = \sin(2\, A)[/tex].
By this identity:
[tex]\begin{aligned}& (2\, \cos(30^\circ)) \cdot (3\, \sin(30^\circ)) \\ &= 3\, (2\, \cos(30^\circ) \cdot \sin(30^\circ)) \\ &= 3\, \sin(2 \times 30^\circ) \\ &= 3\, \sin(60^\circ)\end{aligned}[/tex].
([tex]A = 30^\circ[/tex] in this instance.)
Hence:
[tex]\begin{aligned}&(3\, \tan(45^\circ)) \cdot (4\, \sin(60^\circ)) - (2\, \cos(30^\circ)) \cdot (3\, \sin(30^\circ)) \\ &= 12\, \sin(60^\circ) - 3\, \sin(60^\circ) \\ &= 9\, \sin(60^\circ)\end{aligned}[/tex].
[tex]\displaystyle \sin(60^\circ) = \frac{\sqrt{3}}{2}[/tex]. Therefore, [tex]\displaystyle 9\, \sin(60^\circ) = \frac{9 \sqrt{3}}{2}[/tex].
According to the U.S. Census Bureau, 11% of children in the United States lived with at least one grandparent in 2009 (USA TODAY, June 30, 2011). Suppose that in a recent sample of 1550 children, 214 were found to be living with at least one grandparent. At a 2% significance level, can you conclude that the proportion of all children in the United States who currently live with at least one grandparent is higher than 11%
Answers
Answer:
The pvalue of the test is 0.0001 < 0.02, which means that we reject the null hypothesis and accept the alternate hypohteis that the proportion of all children in the United States who currently live with at least one grandparent is higher than 11%.
Step-by-step explanation:
Proportion of all children in the United States who currently live with at least one grandparent is higher than 11%
This means that the null hypothesis is:
[tex]H_0: p = 0.11[/tex]
And the alternate hypothesis is:
[tex]H_a: p > 0.11[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
0.11 is tested at the null hypothesis:
This means that [tex]\mu = 0.11, \sigma = \sqrt{0.11*0.89}[/tex]
Suppose that in a recent sample of 1550 children, 214 were found to be living with at least one grandparent.
This means that:
[tex]n = 1550, X = \frac{214}{1550} = 0.1381[/tex]
Value of the test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.1381 - 0.11}{\frac{\sqrt{0.11*0.89}}{\sqrt{1550}}}[/tex]
[tex]z = 3.54[/tex]
Pvalue of the test and decision:
This is the probability of finding a sample proportion above 0.1381, which is 1 subtracted by the pvalue of Z = 3.54.
[tex]z = 3.54[/tex] has a pvalue of 0.9999
1 - 0.9999 = 0.0001
The pvalue of the test is 0.0001 < 0.02, which means that we reject the null hypothesis and accept the alternate hypohteis that the proportion of all children in the United States who currently live with at least one grandparent is higher than 11%.

If f(x) is an exponential function where f(- 2.5) = 9 and f(2.5) = 45 , then find the value of f(3.5) , to the nearest hundredth
Answers
The value of g(3.5) is 41.49 to the nearest hundredth
Exponential functionThe standard exponential function is given as g(x) = ab^x
If g(-2.5) = 9 and g(2.5) = 45, hence;
9 = ab^-2.5 .............. 1
45 = ab^2.5 .............2
Divide both equations:
9/45 = b^{-2.5-2.5}
1.5 = b^-5
1.5= 1/b^5
b^5 = 0.6666
b = 0.922
Also since 45 = ab^2.5 .
45 = a(0.922)^2.5
45 = 0.81625a
a = 55.13
g(3.5) = 55.13(0.922)^3.5
g(3.5) = 41.49
Hence the value of g(3.5) is 41.49 to the nearest hundredth

Step-by-step explanation:
Proportion of Americans over 33 who smoke.
Number who smoke divided by the size of the sample.
In this question:
Sample of 1267.
913 don't smoke, so 1267 - 913 = 354 smoke. Then

I will use excel function to resolve this question
Determine the 99% confidence of interval for the difference in mean number of steps by all people
∝ = 0.01
critical value ( t ) = 2.861 ( = TINV ( 0.01, 19 )
Given that :
S1 = 1580
S2 = 2350
n1 = 20
n2 = 20
Difference in mean = x1 - x2 = 1596
Margin of Error = t * [tex]\sqrt{\frac{S^2_{1} }{n_{1} } +\frac{s^2_{2} }{n_{2} } }[/tex]

The midpoint of AB is M(1,-2). If the coordinates of A are (-3, -8), what are the coordinates of B?
Answers
9514 1404 393
Answer:
B(5, 4)
Step-by-step explanation:
The midpoint formula is ...
M = (A +B)/2
Solving for B gives ...
B = 2M -A
B = 2(1, -2) -(-3, -8) = (2+3, -4+8) = (5, 4)
The coordinates of B are (5, 4).
Write the equation of the line in SLOPE- INTERCEPT form:
1. (4, 2); slope 3
2. (3, -1); slope 4
3. (-4,-2), (4,0)
Answers
Answer:
Step-by-step explanation:
1) slope = m = 3
(4 , 2) ; x₁ = 4 ; y₁ = 2
y - y₁ = m(x - x₁)
y - 2 = 3(x - 4)
y - 2 = 3x - 4*3
y - 2 = 3x - 12
y = 3x - 12 + 2
y = 3x - 10 {Slope -intercept form: y = mx + b}
3) (-4 , -2) , (4 , 0)
We have to find the slope
[tex]Slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\= \frac{0-[-2]}{4-[-4]}\\\\=\frac{0+2}{4+4}\\\\=\frac{2}{8}\\\\=\frac{1}{4}\\[/tex]
m = 1/4 ; (4 , 0)
y - y₁ = m(x - x₁)
[tex]y - 0 = \frac{1}{2}(x - 4)\\\\y =\frac{1}{2}x - 4 *\frac{1}{2}\\\\y =\frac{1}{2}x - 2[/tex]

To investigate the relationship between the selling price of a house, y , in dollars, and the size of the house x, in square feet, a local builder collected data on a random sample of 120 houses from a certain region. Assume that the conditions for inference for the slope of a regression line are met. The resulting 95 percent confidence interval for the population slope of the regression line relating price and size is given by (62,99). The local builder claims that the selling price of houses from the region increases by $104 for every extra square foot of space in the house. Which of the following best describes the conclusion that can be reached about this claim based on the confidence interval?
a. The claim is supported by the interval, since the interval does not contain the value 0.
b. The claim is supported by the interval, since all values in the interval are positive.
Ñ. The claim is supported by the interval, since the interval does not contain the value 104.
d. The claim is not supported by the interval, since the interval does not contain the value 0.
e. The claim is not supported by the interval, E since the interval does not contain the value 104.
Answers
Answer:
E) The claim is not supported by the interval, since the interval does not contain the value 104.
Step-by-step explanation:
A claim that the selling price increases by $104 for each square foot increase in space is not supported by the interval. The interval represents plausible values for the slope of the regression line, and the interval does not include the value 104.
