4×2/3 = 8/3 = 2 2/3Stacy is correct
Answer:
[tex]\huge 4 \times \frac{2}{3} = \frac{8}{3} =\boxed{2 \frac{2}{3} }[/tex]
Hence, Stacy is correct.25(x+5\4)^2-16(x7\4)^2 factorize the expression
Since both terms are perfect squares, factor using the difference of squares formula,
a² − b² = (a + b) (a − b) where a = 5(x + 5/4) and b = 4 (x (7/4) ).

An experiment was conducted to see if there is any difference in the amount of weight gained by two groups of pigs fed + Feed # Pigs Mean Weight Gain Standard Deviation Diet A 36 55 3 Diet B 49 53 5.6 1. Construct a 95% confidence interval for the difference of means weight gain using 76 as the degree of freedom. 2. Assume that the variance of the 2 populations are equal, test the hypothesis that pigs fed with Diet A gain more weight than with Diet B at the 0.05 level. 2.
Answer:
Answer:
1. The confidence interval for the difference of means weight gain using 76 as the degree of freedom is -1.664, 5.664
2.The calculated value of t does not lie in the critical region for both d.f 76 and 83 . Therefore we accept our null hypothesis that pigs fed with Diet A gain more weight than with diet B at the 0.05 level
Step-by-step explanation:
# Pigs Mean Weight Gain Standard Deviation
Diet A 36 55 3
Diet B 49 53 5.6
(x`1- x` The 2) ± t∝/2 (v) . Sp √1/n1 + 1/n2
where v= d.f= 76
Here the difference between the sample means is x`1- x`2= 55-53= 2
The pooled estimate for the common variance σ² is
Sp² = 1/n1+n2 -2 [ ∑ (x1i - x1`)² + ∑ (x2j - x`2)²]
= 1/36 +49-2 [ 55²+53²]
Sp = √3025 +2809/83 = 8.38
t (0.025) (76) = 1.992
(x`1- x`2)± t∝/2 (v) . Sp √1/n1 + 1/n2
(2 )± 1.992 (8.38) √ 1/36 + 1/49
(2 )± 3.664
-1.664, 5.664
Par t 2:
The null and alternate hypotheses are
H0 : u1 > u2 against Ha: u1 ≤ u 2
Significance level alpha = 0.05
The critical region t ≥ t (0.05, 76) = 1.665
D.f = n1+n2- 2= 83
The critical region t ≥ t (0.05, 83) = 1.663
t = (x`1- x` ) /. Sp √1/n1 + 1/n2
t= 2/ 8.38 √1/36+ 1/49
t= 2/1.839
t= 1.087
The calculated value of t does not lie in the critical region for both d.f 76 and 83 . Therefore we accept our null hypothesis that pigs fed with Diet A gain more weight than with diet B at the 0.05 level

Which statement does not describe the cosine function?
A. The cycle repeats every 21 radians.
B. Its range includes all real numbers.
C. The cycle starts at y = 1, decreases to y = -1, and then increases
to y = 1.
D. Its reciprocal function is secant.
SUBMIT
The statement (B) " Its range includes all real numbers." is correct because it does not describe the cosine function.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
As we know, the trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
The domain of a cos function is al real numbers and the range of the cos function is [-1, 1]
The cos function is the reciprocal of the secant.
The cycle repeats every 21 radians.
Thus, the statement (B) " Its range includes all real numbers." is correct because it does not describe the cosine function.

Mr. Wells tells his class of 24 that when they have completed the assignment, they may play online math games. At the end of class, 40% of the class is playing online math games. Approximately how many students still need to complete their assignment
Help plz
Answer:
Approximately 14-15
Step-by-step explanation:
This is because 60 percent are not playing games, meaning they haven’t completed their assignment. You then just find 60 percent of 24(the total). That is 14.4 so you round it because you can’t have half of a person, it needs to be a whole number.

The HCF of 104 and X is 52. The HCF of X and 234 is 78. Given that X is a
number between 104 and 234, find X.
Answer:
X = 156
Step-by-step explanation:
52 is a factor of 52, 104, 156, and 208
78 is a factor of 78, 156, and 234.
The commonality here is 156.
Highest common factor (HCF) is the highest factor of two number among all the common factors of the these number.
When finding the factors of two number, some number among these factors are common. The value of the number [tex]x[/tex] is 156.
What is the highest common factor (HCF)?When finding the factors of two number, some number among these factors are common.
Highest common factor (HCF) is the highest factor of two number among all the common factors of the these number.
Given information-
The HCF of 104 and [tex]x[/tex] is 52.
The HCF of [tex]x[/tex] and 234 is 78.
The number [tex]x[/tex] is between 104 and 234.
The factors of 52 (multiples of 52) less than or equal to the number 234 are,
[tex]52,104,156,208[/tex]
The factors of 78 (multiples of 78) less than or equal to the number 234 are,
[tex]78,156,234[/tex]
The common number from both sets is 156.
The number 156 is the value of [tex]x[/tex] which is between the number 104 and 234.
Hence the value of the number [tex]x[/tex] is 156.

A side of the triangle below has been extended to form an exterior angle of 127°. Find
the value of x.
17°
xº
127°
Answer:
x = 53°
Step-by-step explanation:
x + 127° = 180° (sum of angles on a straight line/supplementary angles)
Subtract 127 on both sides
x + 127 - 127 = 180 - 127 (subtraction property of equality)
x = 53°

Answer:
b or B is correct answer out of all
Answer:
I'll try my best to answer this but it could be A. and B.
Step-by-step explanation:
The reasoning for this is because both A and B show correct number lines and the question is asking to select TWO that applyFor A., -2 is the opposite of 2»(-2 is on the left side of the number line, the left side of number lines show negative numbers)
This same rule applys to B. -4 is the opposite of 4.The reason why C. wouldn't be right is because -3 is on the same side where positive numbers would go, on the right side of 0. Meaning C. isn't a correct number line so it can't be the right answer..

Find the measures of center for following. Data Frequency 30 - 34 1 35 - 39 0 40 - 44 3 45 - 49 7 50 - 54 5 55 - 59 10 60 - 64 10 65 - 69 21 70 - 74 12 mode
Answer: the mode is 67.2
Step-by-step explanation:
Given that;
Data Frequency
30 - 34 1
35 - 39 0
40 - 44 3
45 - 49 7
50 - 54 5
55 - 59 10
60 - 64 10
65 - 69 21
70 - 74 12
Mode = ?
we know that mode is the number that has the highest number of appearance of frequency, so in this case, the data group that has the highest frequency (21) is 65 - 69
Lower class boundary of the modal group; L = 65
Frequency of the group before the modal group; Fm-1 = 10
Frequency of the modal group; Fm = 21
Frequency of the group after the modal group; Fm+1 = 12
Group width; G = 4
Now using the formula
Mode = L + [ (Fm - Fm-1) / ( (Fm - Fm-1) + (Fm - Fm+1) ) ] × W
so we substitute
Mode = 65 + [ (21 - 10) / ( (21 - 10) + (21 - 12) ) ] × 4
= 65 + [ 11 / 20] × 4
= 65 + 2.2
= 67.2
Therefore the mode is 67.2
