Answer:
A = 154°
B = 26°
C = 154°
Step-by-step explanation:
✔️A = 180° - 26° (angels on a straight line)
A = 154°
✔️<B and 26° are vertical angles. Therefore,
B = 26° (based in the vertical angles theorem, vertical angles are congruent to each other)
✔️C = A (based in the vertical angles theorem, vertical angles are congruent to each other)
Substitute

arcAE = 126°
Step-by-step explanation:
Note that arcAD is a diameter therefore arcAD = 180°. And arcAD = arcAE + arcED
Also note that the inscribed angleEAD intercepts the arcED and according to the inscribed angle theorem,
angleEAD = (1/2)arcED
or
arcED = 2×angleEAD = 2×(27°) = 54°
This means that the arcAE is
arcAE = arcAD - arcED
= 180° - 54°
= 126°
[tex]\\ \sf\longmapsto arc \overset{\sim}{ED}=2(<A)=2(27)=54°[/tex]
Now
[tex]\\ \sf\longmapsto arc\overset{\sim}{AE}+arc\overset{\sim}{ED}=180[/tex]
[tex]\\ \sf\longmapsto arcc\overset{\sim}{AE}=180-54=126°[/tex]

Cooper invested $3,100 in an account paying an interest rate of 2%
compounded quarterly. Robert invested $3,100 in an account paying an
interest rate of 3 % compounded continuously.After 12 years, how much
more money would Robert have in his account than Cooper, to the nearest
dollar?
Answer:
Rounded to the nearest dollar, Robert will have $ 505 more than Cooper on his account.
Step-by-step explanation:
Given that Cooper invested $ 3,100 in an account paying an interest rate of 2% compounded quarterly, while Robert invested $ 3,100 in an account paying an interest rate of 3% compounded continuously, to determine, after 12 years, how much more money would Robert have in his account than Cooper to the nearest dollar, the following calculation must be made:
Compound interest formula: Initial x (1 + interest / composition) ^ composition x years
Continuous compound interest formula: Initial x exp ^ (interest x years)
Cooper:
3,100 x (1 + 0.02 / 4) ^ 12x4 = X
3,100 x (1 + 0.005) ^ 48 = X
3,100 x 1,005 ^ 48 = X
3,100 x 1,270 = X
3,938.51 = X
Robert:
3,100 x 2.71828182845904 ^ (3x12) = X
4,443.32 = X
4,443.32 - 3,938.51 = X
504.51 = X
Therefore, rounded to the nearest dollar, Robert will have $ 505 more than Cooper on his account.

A paper store spent 1/4 of all the money they earned in December to buy new inventory. It used 1/2 of the rest of the money to pay bills. Then, they still had $3,000 left over. How much money did the store earn in December?
Answer:
$8,000
Step-by-step explanation:
Let the store earned $x in December.
Therefore,
Money spent to buy new inventory [tex] =\frac{1}{4} x[/tex]
Remaining money [tex] = x - \frac{1}{4} x =\frac{3}{4} x[/tex]
Money used to pay bills [tex] =\frac{1}{2} \times \frac{3}{4} x=\frac{3}{8} x[/tex]
Money still left over = $3,000
Total money earned in December [tex]= \frac{1}{4} x+ \frac{3}{8} x+3,000[/tex]
[tex]\therefore x= \frac{1}{4} x+ \frac{3}{8} x+3,000[/tex]
[tex]\therefore x= \frac{2}{8} x+ \frac{3}{8} x+3,000[/tex]
[tex]\therefore x= \frac{5}{8} x+ 3,000[/tex]
[tex]\therefore x- \frac{5}{8} x=3,000[/tex]
[tex]\therefore \frac{8x-5x}{8} =3,000[/tex]
[tex]\therefore \frac{3x}{8} =3,000[/tex]
[tex]\therefore x =3,000\times \frac {8}{3}[/tex]
[tex]\therefore x =1,000\times 8[/tex]
[tex]\therefore x =\$8,000[/tex]
Thus, total money earned in December is $8,000.

Answer:
95% confidence interval for the proportion of days that IBM stock increases.
(0.45814 , 0.58146)
Step-by-step explanation:
Step:1
Given that a stock market analyst notices that in a certain year, the price of IBM stock increased on 131 out of 252 trading days.
Given that the sample proportion
[tex]p^{-} = \frac{131}{252} = 0.5198[/tex]
Level of significance = 0.05
Z₀.₀₅ = 1.96
Step:2
95% confidence interval for the proportion of days that IBM stock increases.
[tex](p^{-} - Z_{0.05} \frac{\sqrt{p(1-p)} }{\sqrt{n} } , p^{-} + Z_{0.05} \frac{\sqrt{p(1-p)} }{\sqrt{n} } )[/tex]
[tex](0.5198 - 1.96(\sqrt{\frac{0.5198(1-0.5198)}{252} } , 0.5198 +1.96(\sqrt{\frac{0.5198(1-0.5198)}{252} })[/tex]
(0.5198 - 0.06166 , 0.5198+0.06166)

Step-by-step explanation:
A psychologist would like to examine the effect of fatigue on mental alertness. An attention test is prepared which requires subjects to sit in front of a blank TV screen and press a response button each time a dot appears on the screen. A total of 110 dots are presented during a 90-minute period, and the reach subject. Two groups of subjects are selected. The first group (n 5) is tested after they have been kept awake for 24 hours. The second group (n-10) is tested in the morning after a full night's sleep. The data for these two samples are as follows:
Awake 24 hours rested
x=35 X=24
ss=120 ss =360
On the basis of these data, can psychologist conclude that fatigue significantly increases errors on an attention task? Test with α-05 and report effect size.
Answer:
The calculated value of t= 0.1908 does not lie in the critical region t= 1.77 Therefore we accept our null hypothesis that fatigue does not significantly increase errors on an attention task at 0.05 significance level
Step-by-step explanation:
We formulate null and alternate hypotheses are
H0 : u1 < u2 against Ha: u1 ≥ u 2
Where u1 is the group tested after they were awake for 24 hours.
The Significance level alpha is chosen to be ∝ = 0.05
The critical region t ≥ t (0.05, 13) = 1.77
Degrees of freedom is calculated df = υ= n1+n2- 2= 5+10-2= 13
Here the difference between the sample means is x`1- x`2= 35-24= 11
The pooled estimate for the common variance σ² is
Sp² = 1/n1+n2 -2 [ ∑ (x1i - x1`)² + ∑ (x2j - x`2)²]
= 1/13 [ 120²+360²]
Sp = 105.25
The test statistic is
t = (x`1- x` ) /. Sp √1/n1 + 1/n2
t= 11/ 105.25 √1/5+ 1/10
t= 11/57.65
t= 0.1908
The calculated value of t= 0.1908 does not lie in the critical region t= 1.77 Therefore we accept our null hypothesis that fatigue does not significantly increase errors on an attention task at 0.05 significance level

The mean for a data set is 60. The Z-score for
data point a is 0. The z-score for data point b
is -0.4. Which are the possible values for data
point a and b?
A. a = 0 and b = 61.2
B. a = 0 and b = 58.8
C. a = 60 and b = 61.2
D. a = 60 and b = 58.8
Answer:
D. a = 60 and b = 58.8
Step-by-step explanation:
Z-score:
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Z-score for data point a is 0.
This means that a is the mean, that is, a = 60.
The z-score for data point b is -0.4.
This means that b must be a value below the mean, that is, a value below 60.
The option that satisfies a = 60 and b < 60 is option D, which is the answer.
