The general equation is given as,
Un+1 = (Un)^3+2
here, n = number of the sequential entries like 0,1,2,3... so on.
so we get here as,
Uo = -3 , so we find U1 and U2
U1 = n+1 = 0+1
so,
===> U1 = (-3)^3 +2
===> U1 = -27 + 2 ==> U1 = -25
now, U2
U2 = n+1 = 1+1
so,
U2 = (-25)^3 + 2
U2 = -15625 + 2 ===> U2 = -15623
hence,
U1 = -25 and U2 = -15623

Penny is the manager of a nursery for pre-school children.
She knows that the ratio of the number of adults to the number of children
must be 1:8
Penny has 56 children at the nursery.
(a) Work out the number of adults Penny needs for 56 children.
Answers
Answer: 7
Step-by-step explanation:
We know that the ratio adults: children must be 1:8.
So if there are 58 children the ration is x: 56
56/8 (to find the number of adults) = 7
7:56 = 1:8

Consider the following problem: The box fill weight of Frosted Flakes breakfast cereal follows a normal distribution with a mean of 9.75 ounces and a standard deviation of 0.27 ounces. A sample of 25 boxes filled this morning showed a mean of 9.85 ounces. At the 0.05 significance level, can we conclude that the mean weight is more than 9.75 ounces per box
Answers
Answer:
Yes, we can
Step-by-step explanation:
H0 : μ = 9.75
H1 : μ > 9.75
n = 25 ; xbar = 9.85 ; σ = 0.27
The test statistic:
T = (xbar - μ) ÷ (σ / √n)
T = (9.85 -9.75) ÷ (0.27 ÷ √25)
T = 0.1 ÷ 0.054
T = 1.85
We can obtain the Pvalue from the test statistic using the Pvalue calculator :
Pvalue at t score = 1.85 ; 24 = 0.038
If Pvalue < α ; Reject H0
α = 0.05
Since Pvalue < α ; We reject H0 and conclude that mean weight is more than 9.75 ounces per box

y = -2x + 1.5
Step-by-step explanation:
line that passes through the given points (-1,3.5),(1,-0.5), (3,-4.5)
slope (m) = (-0.5 - 3.5) / (1 - -1) = -4 / 2 = -2
(y - -4.5) / (x - 3) = -2 ... pass (3,-4.5)
y + 4.5 = -2x +6
y = -2x + 1.5
A study examined the effectiveness of an ear-molding technique used to correct ear deformities in newborns without the need for surgery. A plastic mold was placed around the deformed ear shortly after birth for about two weeks. The study reports that 152 of 158 procedures were successful. We would like to estimate with 95% confidence the true proportion of successful ear-molding procedures among all newborns needing ear-deformity correction. We can use
Answers
Answer:
The 95% confidence interval for the true proportion of successful ear-molding procedures among all newborns needing ear-deformity correction is (0.932, 0.992).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The study reports that 152 of 158 procedures were successful.
This means that [tex]n = 158, \pi = \frac{152}{158} = 0.962[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.962 - 1.96\sqrt{\frac{0.962*0.038}{150}} = 0.932[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.962 + 1.96\sqrt{\frac{0.962*0.038}{150}} = 0.992[/tex]
The 95% confidence interval for the true proportion of successful ear-molding procedures among all newborns needing ear-deformity correction is (0.932, 0.992).
The 95% confidence interval of the true proportion of successful ear-molding procedures among all newborns needing ear-deformity correction is; CI = (0.9322, 0.9918)
We want to find confidence interval and the formula is;
CI = p^ ± z√(p^(1 - p^)/n)
We are told that the study reports that 152 of 158 procedures were successful. Thus;
n = 158
p^ = 152/158
p^ = 0.962
Now, we want to find the confidence interval at a 95% confidence level.
The critical z value for 95% confidence level is;
z = 1.96
Thus;
CI = 0.962 ± 1.96√(0.962(1 - 0.962)/158)
CI = 0.962 ± 0.0298
CI = (0.962 - 0.0298), (0.962 + 0.0298)
CI = (0.9322, 0.9918)
