Answer:
neither (y=(x-.5)^2-6.25)linear (y=4x+6)exponential (y=3^x)Step-by-step explanation:
1. Successive y-values have neither a common difference nor a common ratio. The table is neither linear nor exponential.
__
2. Successive y-values differ by 4. The table is linear.
__
3. Successive y-values have a ratio of 3. The table is exponential.
_____
Additional comment
For evenly-spaced x-values, the y-values will have a common difference for a linear function, and a common ratio for an exponential function.
If the table can be represented by a polynomial function, the level at which differences are constant will tell the degree of the polynomial. First differences are constant for a degree 1 (linear) function. Second differences are constant for a degree 2 (quadratic) function. This is the case in Table 1, where second differences are 2.
2x+2y= 24
x=3y
What is the value of x+y?
Answer:
x = 9
y = 3
Step-by-step explanation:
2x + 2y = 24 is the same as x + y = 12
using substitution, x = 12-y
12 - y = 3y
12 = 4y
y = 3
x = 3(3)
x = 9
The value of x + y for the given system of equations 2x+2y= 24 and x=3y will be 12.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
The equation must be constrained with some constraints.
As per the given system of equations,
2x+2y= 24
x=3y
Take common 2 from 2x+2y= 24 as
2(x + y) = 24
Divide by 2 into both sides
x + y = 12
Hence "The value of x + y for the given system of equations 2x+2y= 24 and x=3y will be 12".

A circle graph titled June. Poreg, 173; Quilren, 184; Dinztop, 148; Quilren 2, 153; Juvanto, 212. If the changes in sales between May and June continue at the same rate, how many total computers will be sold in July? a. 534 b. 721 c. 1,019 d. 1,254
Answer:
The answer is B, 721
Step-by-step explanation:
edge 2021
The total computers will be sold in July will be equal to 98 computers.
How is the percentage of a value calculated?The percentage represents a value divided by 100. In this way, saying 25% of a value is the same as saying 25 out of 100, that is, 25 divided by 100. And to find the exact number of absentees in the event, just multiply the whole by the percentage
So in this case, we have the information that:
May: 223 Dinztop salesJune: 148 Dinztop sales.Using the percentage we have:
[tex]p=\frac{148}{223} = 0.6637[/tex]
This value in percentage that will be:
[tex]0.6637*100\%= 66.37\%[/tex]
Because of the same percent rate, the amoutns sold in June:
[tex]66.37\%*148=98[/tex]

The value of the equation is x = 2
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
x + 5 = 7 be equation (1)
On simplifying the equation , we get
Subtracting 5 on both sides of the equation , we get

Hello your question is poorly written the complete question is attached below
answer :
a) H0 : p1 = p2
Ha : p1 ≠ p2
b) Z = -0.58
c) P-value = 0.561915
d) we will reject the Alternative hypothesis
Step-by-step explanation:
For sample 1 ; n1 = 254 , x1 = 28
For sample 2 ; n2 = 301 , x2 = 38
level of significance ∝ = 0.01
P1 = X1 / n1 = 28 / 254 = 0.1102
P2 = X2 / n2 = 38 / 301 = 0.126
a) Determine the null and alternate hypothesis
H0 : p1 = p2
Ha : p1 ≠ p2
b) Determine Test statistic
we perform a Z-statistic to test the hypothesis
Z = [tex]\frac{p1-p1 }{\sqrt{( p(1-p)*(\frac{1}{n1}+\frac{1}{n2}) ) } }[/tex] -------- ( 1 )
p = ( x1 + x2 ) / ( n1 + n2 )
= ( 28 + 38 ) / ( 254 + 301 ) = 0.1189
Where: p = 0.1189 , p1 = 0.1102 , p2 = 0.126 ( input values into equation 1 )
∴ Z = -0.58
c) Determine P-value
P-value = 0.561915 ( using excel function )
d) conclusion : since p-value > 0.01 ( level of significance ) we do not reject the null hypothesis. therefore it proves that p1 = p2

Answer:
a) 179
b) 21
Step-by-step explanation:
When making a Venn diagram for a problem like this, it often works well to fill in the "both" quantity first. Then that is subtracted from the number for grocery to find "grocery only", and from the number for drug store to find "drug store only." The sum of the numbers inside the circles (88+33+58) is the number who shopped at the grocery or drug store. The number who shopped at neither is the difference between this number and the total number of shoppers (200-179).

Step-by-step explanation:
Foresters want to estimate the average age of trees in a stand. Determining age is cumbersome, because one needs to count the tree rings on a core taken from the tree. In general, though, the older the tree, the larger the diameter, and diameter is easy to measure. The foresters measure the diameter of all 1132 trees and find that the population mean equals 10.3. They then randomly select 20 trees for age measurement
Answer:
hello your question has some missing information attached below is the missing information
answer : mean ratio of estimate = 117.62
standard error ( SE ) = 3.9765
Step-by-step explanation:
Given data : n = 20, μx = 10.3 , N = 1132
∑ age ( yi) = ( 125 + 119 + --------- + 99 ) = 2148
∑ ( Y - rX)^2 = 6116.728
mean of age ( y ) = ∑ y / 20 = 2148 / 20 = 107.4
mean of diameter ( x ) = ∑x /20 = 188.1 / 20 = 9.405
∴ ratio estimate = y /x = 107.4 / 9.41 = 11.4195
i) The mean of ratio estimate
= 11.4195 * μx = 11.4195 * 10.3 = 117.6204
ii) determine the standard error ( SE )
calculate ; [tex]s^{2} _{r}[/tex] = 1 / ( n-1 ) * ∑ (Y - rX)^2 = 1/19 ( 6116.728 ) = 321.933
Var ( μr ) = [ ( N - n ) / N*n ]*[tex]s^{2} _{r}[/tex] = [ ( 1132 - 20 ) / (1132*20) ] * 321.933
= 15.81226
therefore the SE = √15.81226 ≈ 3.9765
