Answer:
65.5
Step-by-step explanation:
Using the relation :
Xbar ± Margin of error
Margin of Error = Zcritical * s/√n
The Zcritical value at 95% = 1.96
Hence,
Margin of Error = 1.96 * 2.5/√60
Margin of Error = 1.96 * 0.3227486
Margin of Error = 0.6326
Lower boundary = 65.5 - 0.6326 = 64.867
Upper boundary = 65.5 + 0.6326 = 66.133
(64.867 + 66.133) / 2

g + 19 = 38
Explain how to get the answer pls!
In order to find out what g is equal too,u must subtract 19 from both sides of the equation to get
g +19-19=38-19
the nineteens cancel out getting
g=38 -19
g=19
A rectangle has coordinates (2, 6) (9, 6) (9, 10) and (2, 10) on a grid with 1 cm squares. What is the area of the shaded rectangle?
Answer:
Area of Rectangle = 28 cm²
Step-by-step explanation:
Given - A rectangle has coordinates (2, 6) (9, 6) (9, 10) and (2, 10) on a grid with 1 cm squares.
To find - What is the area of the shaded rectangle?
Solution -
The graph of the rectangle is as follows :
From the diagram, e can see that
Length of Rectangle = 7 units (cm)
Breadth of Rectangle = 4 units (cm)
We know that,
Area of Rectangle = Length × Breadth
= 7 × 4
= 28 cm²
⇒Area of Rectangle = 28 cm²

Will mark brainliest please help :(
Answer:
-38
Step-by-step explanation:
-38 - 7 = -45
-45 divided by 9 = -5
Answer: y = -38
The value of y is -38
Step-by-step explanation:
First, you want to multiply all terms by the same value to eliminate fraction denominators:
-5 = (y-7) / (9)
9(-5) = 9 * (y - 7) / (9)
Then you will cancel multiplied terms that are in the denominator:
9(-5) = 9 * (y - 7) / (9)
9(-5) = y - 7
Then multiply the numbers:
9(-5) = y - 7
-45 = y - 7
Solve and simplify:
y = -38
Solution:
y = -38

Mark spent a total of $16.35 to buy a total of 11 bags of carrots and bags of tomatoes. Each bag of carrots costs $1.05, and each bag of tomatoes costs $1.65. How many bags of carrots and how many bags of tomatoes did he buy? Enter your answers in the boxes below. (Use x for carrots and y for tomatoes.)
Answer:
x= 12
Step-by-step explanation:
The solution is, he bought 3 bags of carrots and 8 bags of tomatoes.
What is equation?An equation can be stated as a mathematical statement that is made up of two expressions connected by an equal sign. In its normal form in algebra, it can be said as of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
Mark spent a total of $16.35 to buy a total of 11 bags of carrots and bags of tomatoes.
Each bag of carrots costs $1.05, and each bag of tomatoes costs $1.65.
let, he bought x bags of carrots and y bags of tomatoes.
now, we get,
x+y = 11 ....(1)
1.05x + 1.65y = 16.35 ....(2)
solving this, we get,
x= 3
y= 8
Hence, The solution is, he bought 3 bags of carrots and 8 bags of tomatoes.

What is the range of the function shown in the graph below?
Answer:
y= -3/2X + 2
Step-by-step explanation:
we get the gradient by picking any two points from the graph( it a linear graph)
using the point:
(x,y)= (-2,5) , (4,-4)
using M= (y2-y1)/x2-x1)
we get our gradient to be -9/6 which is
-3/2
using the equation of a straight line graph which is
y-y1=m(x-x1) and the point (4,-4)
we get
y-(-4)=-3/2(x-4)
----> y+4= -3/2x + 6
make y subject of the formula to take the form
y=mx+c
we get :
y=-3/2x + 2

1. For AEFG shown below, construct the median from E to side FG. Leave all construction marks.
can somebody please describe where i put the construction marks? it’d be really helpful.
Answer:
Step-by-step explanation:
A median bisects the side it intersects with, so the first step is to bisect FG.
Set the compass slightly larger than half of FG.
Put the point on F and draw a half circle that intersects FG and faces G.
Put the point on G and draw a half circle that intersects FG and faces F.
Draw a line through the intersections of the two half circles, and the intersection of that line with FG is FG's midpoint.
Connect the midpoint with E, and the connecting line is the median.

what is the rate of change for y=5.6x+7
Answer:
5.6
Step-by-step explanation:
The equation is put in y = mx + b
where m = slope ( rate of change ) and b = y intercept
5.6 = m and 7 = b
Hence the rate of change for y = 5.6x + 7 is 5.6
