The solution is Option B.
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
x = 7 - 5
x = 2
Therefore , the value of x is 2
Hence , the equation is x = 2

A shopping center includes a grocery store and a drug store. One afternoon, a total of 200 people visited the shopping center, and 121 shopped at the grocery store, 91 shopped at the drug store, and 33 shopped at both businesses. a) How many people shopped at the grocery store or the drug store? b) How many people shopped at neither the grocery store nor the drug store?
Answers
9514 1404 393
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).

Solve the equation
x=11
4 angles are 360 degrees, we know 2 angles.
107+107= 214
360-214= 146
146 is the two angles added up, divide them by 2 to find each side

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

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
Answers
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

Answer:
area = 220.5 ft²
Step-by-step explanation:
2(Length) + 2(10.5) = 63 feet
2L + 21 = 63
subtract 21 from each side of the equation:
2L = 42
divide both sides by 2:
L = 21 feet
area = L x W = 21 x 10.5 = 220.5 ft²
Answer:
A = 220.5 ft
Step-by-step explanation:
[tex]2(Length) + 2(10.5) = 63 feet\\[/tex]
[tex]2L + 21 = 63\\[/tex]
[tex]63 - 21[/tex]
[tex]2L = 42[/tex]
[tex]42/2[/tex]
L = 21 feet
[tex]A=l * w[/tex]
[tex]21 x 10.5 = 220.5 ft^{2}[/tex]

wrap this box.
Answers
Answer: $46.08
Step-by-step explanation:
Find the surface Area of the box
the bases are 12*12= 144 times 2 bases 144*2= 288
The area of each side is 12*18=216 times 4 sides 216*4=864
add the totals together to find the total surface area 288+864=1152
total surface area is 1152 inches. Multiply by the cost per square inch
1152*.04= 46.08
