The value of a and the value of b is 6 and 5.
We can solve this problem by few steps, If we change the representation of power by replacing all powers according to √x or [tex] {x}^{1/2} [/tex]. We know that, [tex] {x}^{m/n × n/b } = {x}^{m/b} [/tex]
So, using this we can write, [tex] {4x}^{1/2 \times 6} + {x}^{1/2 \times 10/2} = {4 \sqrt{x} }^{6} + { \sqrt{x} }^{5} [/tex]..............(1)
Now if we compare the value of ( 1 ) with
[tex] {4 \sqrt{x} }^{a} + { \sqrt{x} }^{b} [/tex], we can easily find out the value of a and b and it is, a = 6 and b = 5
Thus, the value of a and b is 6 and 5.

The length of the rectangle is 30 cm.
Work out the width of the rectangle.
Optional working
Answer: width =

cm
The width of rectangle is 20 cm
As is seen in the picture, there are 6 squares at the length of rectangle and 4 squares at the width of rectangle. Also, as per the known fact, each side of square is same. So, we will find the side of square to calculate width of rectangle.
Length of rectangle = 6 × side of square
Side of square = 30 ÷ 6
Side of square = 5 cm
Width of rectangle = 4 × side of square
Width of rectangle = 4 × 5
Width of rectangle = 20 cm
Hence, the width of rectangle is 20 cm.

Solve the following system of equations.
5 a-b=17
3 a+2 b=5
Answer:
a = 3 , b = - 2
Step-by-step explanation:
5a + b = 17 → (1)
3a + 2b = 5 → (2)
multiplying (1) by 2 and adding to (2) will eliminate b
10a + 2b = 34 → (3)
add (2) and (3) term by term to eliminate b
13a + 0 = 39
13a = 39 ( divide both sides by 13 )
a = 3
substitute a = 3 into either of the 2 equations and solve for b
substituting into (1)
5(3) + b = 17
15 - b = 17 ( subtract 15 from both sides )
- b = 2 ( multiply both sides by - 1 )
b = - 2
then solution is a = 3 , b = - 2

The possible triples are: (3, 3, 3), (4, 2, 4) as seen by counting theorem.
What is counting theorem?The basic counting principle is a method for keeping track of all the potential outcomes in a situation. According to this statement, there are n m n times m n methods to carry out both of these acts if there are n ways to execute one activity and m ways to perform another action after that.Now, by the counting principle,
Give the pickets numbers like 1, 2, and so on. If Picket 4 is painted, Ulysses must also paint the remaining Pickets. Let's say Harold paints picket number 4. If Harold and Ulysses both paint picket 7, Ulysses is unable to paint picket 5, so Tanya does. The picket is painted by Ulysses, and (h, t, u) = (3, 3, 3). However, let's say Tanya paints picket 4. Harold paints picket 5 since Ulysses is unable to do so or then there won't be anything left to paint. Ulysses paints picket 7 as a result, and (h, t, u) = (4, 2, 4).Hence, the possible triples are: (3, 3, 3), (4, 2, 4).

The equation can be written as 2.75x + 3.10 = 27.85
The number of miles in the taxi ride is 9
How to calculate the number of miles in the taxi ride ?The taxi company was charged a pick-up fee of $3.10
It also charges $2.75 per mile
The total fare is $27.85
The equation can be written as
2.75x + 3.10 = 27.85
Collect the like terms to get the value of x
2.75x= 27.85 - 3.10
2.75x = 24.75
divide both sides by the coefficient of x which is 2.75
2.75x/2.75= 24.75/2.75
x= 9

We wish to test the hypothesis that the mean weight of a population of fish is 140g. With sigma=15 g and alpha= 0.05, and a sample of 36 fish, find a) the mean values which would lead to a rejection of the hypothesis and Use a two-tailed test.
Using the z-distribution, it is found that mean weights less than 135.1g and more than 144.9 would lead to a rejection of the hypothesis.
What is the critical value of the test?We have a two-tailed test, with a significance value of α = 0.05, hence, using a z-distribution calculator, the critical value is given by:
|z| = 1.96 -> z < -1.96 or z > 1.96.
What is the test statistic?The test statistic is given as follows:
[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 of the population.n is the sample size.For this problem, the parameters are given as follows:
[tex]\mu = 140, \sigma = 15, n = 36[/tex]
The lower bound of acception is found as X when z = -1.96, hence:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
-1.96 = (X - 140)/(15/6)
-1.96 = (X - 140)/(2.5)
X - 140 = -1.96 x 2.5
X = 135.1.
The upper bound of acception is found as X when z = 1.96, hence:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
1.96 = (X - 140)/(15/6)
1.96 = (X - 140)/(2.5)
X - 140 = 1.96 x 2.5
X = 144.9.
Hence:
Mean weights less than 135.1g and more than 144.9 would lead to a rejection of the hypothesis.

Find the partial sum sn of the geometric sequence that satisfies the given conditions. a3 = 36, a6 = 288, n = 5
The value of the partial sum of geometric sequence with terms a3 = 36 and a6 = 288 is given by 297. This is obtained by using the concept of partial sum of a geometric progression.
What is geometric progression?
Geometric progression is defined as a series of numbers having a fixed ratio between each term and its preceding term. It is also known as a geometric sequence or G.P., and is exemplified as a1, a2, a3, ….., an
Here, the first term is denoted by a1 and its common ratio is shown by r, which is calculated using the formula a2 by a1. The partial sum of a G.P. is given by a1 ( rn - 1 ) / ( r - 1 ), when r > 1 and a1 ( 1 - rn ) / ( 1 - r ), when r < 1
Calculation of the partial sum of the geometric sequence that satisfies the given conditions. a3 = 36, a6 = 288, n = 5
Given:
Value of a3 = 36
Value of a6 = 288
n = 5
a3 = ar2 — 1
a6 = ar5
Now, a6 / a3 = ar5 / ar2 = 288 / 36
r3 = 8
Taking cube root both sides, we get,
r = 2
Putting the value of r in equation 1,
a3 = a(2)2
36 = 4a
a = 9
As r > 1, using the formula for Sn as a(rn - 1) / (r - 1)
Sn = 9(2n - 1) / (2 - 1)
Sn = 9(2n - 1)
Using n = 5, we have,
Sn = 9[(2)5 - 1]
Sn = 9(32 - 1)
Sn = 9 × 33
Sn = 297
Hence, the value of the partial sum of a G.P. is 297

the degree of correlation among independent variables in a regression model is called . a. multicollinearity b. the coefficient of determination c. interaction d. the sum of squared errors (sse)
Multicollinearity refers to the degree of correlation among independent variables in a regression model.
What is Multicollinearity?In a multiple regression model, one predictor variable can be predicted linearly from the others using a high degree of accuracy when there is a phenomenon known as multicollinearity (also known as collinearity). In this case, minor adjustments to the model or the data may cause the multiple regression's coefficient estimates to fluctuate unpredictably. Multicollinearity only impacts calculations pertaining to specific predictors; it has no impact on the predictive capability or reliability of the model as a whole, at least within the sample data set. In other words, a multivariate regression model with collinear predictors can show how well the complete set of predictors predicts the outcome variable, but it could not provide accurate information about any particular predictor or which predictors are redundant in relation to others.
