64x^6

Step-by-step explanation:

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

Step-by-step explanation:

To find the Laplace inverse of the above problem, we have to first solve the problem as a partial fraction, hence:

[tex]\frac{5s}{s^2+3s-4}=\frac{5s}{s^2+4s-s-4} \\\\=\frac{5s}{s(s+4)-1(s+4)}\\\\=\frac{5s}{(s-1)(s+4)}=\frac{A}{s-1}+\frac{B}{s+4}\\\\= \frac{A(s+4)+B(s-1)}{(s-1)(s+4)}\\\\Hence:\\\\\frac{A(s+4)+B(s-1)}{(s-1)(s+4)}=\frac{5s}{(s-1)(s+4)}\\\\A(s+4)+B(s-1)=5s\\\\to\ find \ A,put\ s=1:\\\\A(1+4)+B(1-1)=5(1)\\\\5A=5\\\\A=1\\\\to\ find \ B,put\ s=-4:\\\\A(-4+4)+B(-4-1)=5(-4)\\\\-5B=-20\\\\B=4\\\\Hence:\\\\\frac{5s}{s^2+3s-4}=\frac{1}{s-1}+ \frac{4}{s+4}\\\\[/tex]

[tex]L^{-1} [\frac{5s}{s^2+3s-4}]=L^{-1}[\frac{1}{s-1} ]+L^{-1}[\frac{4}{s+4} ]\\\\But\ L^{-1}[\frac{1}{s-a} ]=e^{at}\\\\Hence:\\\\L^{-1} [\frac{5s}{s^2+3s-4}]=L^{-1}[\frac{1}{s-1} ]+L^{-1}[\frac{4}{s+4} ]=e^{t}+4e^{-4t}\\\\=e^{t}+4e^{-4t}[/tex]

The statement (B) " Its range includes all real numbers." is correct because it does not describe the cosine 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.

Answer:

The equation of the perpendicular line to y=-4*x-5 is [tex]y=\frac{1}{4}*x+\frac{7}{2}[/tex]

Step-by-step explanation:

Perpendicular lines are two or more lines that intersect at an angle of 90 degrees. Being  y = m * x + b the equation of a line, two lines, with a slope other than zero, are orthogonal or perpenducillary if and only if the product of their slopes is -1. In other words, if two lines are perpendicular, they have their slopes reversed and sign changed.

In this case, with y = -4x-5 the slope will be -4. So the slope of the perpendicular line will be [tex]\frac{1}{4}[/tex]. Then the equation of the perpendicular line will be:

[tex]y=\frac{1}{4}* x+b[/tex]

To find the value of b, you know the value of the point (-2,3). So x = -2 and y = 3. Replacing in the equation of the perpendicular line, you have:

[tex]3=\frac{1}{4}* (-2)+b[/tex]

Solving, you get:

[tex]3=-\frac{1}{2}+b[/tex]

[tex]3+\frac{1}{2}=b[/tex]

[tex]\frac{7}{2}=b[/tex]

The equation of the perpendicular line to y=-4*x-5 is [tex]y=\frac{1}{4}*x+\frac{7}{2}[/tex]

Answer:

The number of applications received is approximately 30,000 and the success rate is approximately 32%.

Step-by-step explanation:

The application curve is red in colour, on 2001 trace it the right hand side, the number of applications received is approximately 30,000.

The percentage of grants funded is equal to the success rate which is the curve green in colour. On 2001 trace the curve to the left hand side, the success rate is approximately 32%.

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:

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.

Answer:

$3700

Step-by-step explanation:

Given that:

Initial amount = $1400

Amount deposited per week = 50

Amount after 47 weeks =?

Using the Arithmetic Progression relation :

Tn = A + (n - 1)d

Weekly deposit = d = 50

A = initial / first deposit = 1400

n = number of deposits

T47 = 1400 + (47 - 1)50

T47 = 1400 + (46)*50

T47 = 1400 + 2300

T47 = 3700

Answer:

$3750

Step-by-step explanation:

T47 = 3750

Answer: T= 3.54

Step-by-step explanation:

Step 1

Given that

The time period, T, s doirectly proportional  to the square root of the length, d, of the pendulum, we have that

T  ∝  [tex]\sqrt{d}[/tex]

Introducing the constant of proportionality, we have that

T= K[tex]\sqrt{d}[/tex].

Step 2

When d=6, T=5, K =?

T= K[tex]\sqrt{d}[/tex].

5 = k[tex]\sqrt{6}[/tex]

5=  k x 2.44949

k =5/2.44949

k =2.041

Therefore, when d = 3 , T= ?

T= K[tex]\sqrt{d}[/tex]

T= 2.041 x [tex]\sqrt{3}[/tex]

T= 3.53511≈ 3.54

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:

»(-2 is on the left side of the number line, the left side of number lines show negative numbers)

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..

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.

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.
