Given the value of the standard deviation of  population, if the critical value is 0.65, the Margin of error will be 0.65.

Margin of error simply shows how many percentage points a results will differ from the real population value.

It can be expressed as;

Margin of error = Critical value × Standard deviation

Given that;

Margin of error = Critical value × Standard deviation

Lets take critical value to be 0.05

Hence,

Margin of error = 0.05 × 13

Margin of error = 0.65

Therefore, given the value of the standard deviation of  population, if the critical value is 0.65, the Margin of error will be 0.65.

Answer:

Step-by-step explanation:

AB=6 cm

BX=1/2 AB=1/2 ×6=3 cm

BC=8 cm

BY=1/2×BC=1/2×8=4 cm

perpendicular bisector of a chord always passes through the center.

so quadrilateral OXBY is a rectangle.

Perimeter=2(BX+BY)=2(3+4)=2×7=14 cm.

Given :

To find :-

Solution :-

Taking the given equation ,

The cost of pen and colored pencils per piece is =10.85

The new total length of both Betty and Beth is =227.2cm

Total number of pens Randy needs to buy = 5

Total number of colored pencils Randy needs to buy= 3

The both items are bought at the same prize = a

The cost of five pens is = 5× a = 5a

The cost of colored pencils is = 3 × a= 5a

The money needed to spend on the items= 86.78

To find the cost of each item which is a ,

5a + 3a = 86.78

(5+3) a= 86.78

8a = 86.78

therefore a = 86.78/8

= 10.85

Therefore the prize of each item is = 10.85. That is option B

Betty's height = 119.2 cm

Beth's height = 105.6cm ( which remained the same)

But Betty's height after 6 months = (6× 0.4) + 119.2

= 2.4 + 119.2

= 121.6 cm

Therefore, the total new height= 121.6 + 105.6

= 227.2cm

That is option A.

Answer:

y = 3x + 3

Step-by-step explanation

Values on the y-axis are increasing by 3, while values on the x axis are increasing by 1, so the slope is 3/1 or just 3

To find b, you the slope, 3, from the 6. You also subtract 1 from 1 in the x-collum. You do this to find the y-intercept, or when x=0.

Answer:

turning point: (1, 4)

Roots: (-1, 0), (3, 0)

Step-by-step explanation:

The turning point is the vertex of the parabola, which occurs at point (1, 4).   The roots are the areas where the graph crosses the x-axis, referred to as the x-intercepts. The graph crosses the x-axis at points (-1, 0) and (3, 0).

Answer: Explanation below.

Step-by-step explanation:  A good question, since working with inequalities  and using the same operations as with "=" equations is a bit uncomfortable.  I don't have a mathematical proof for this operation, but approach it with a "Why not?" attitude.  If 9>6 and 130 > 30, why wouldn't 139>36?  There is nothing in the add operation that should upset the basic inequality.  I suggest https://www.storyofmathematics.com/inequalities-math for more information.

Answer:

8

Step-by-step explanation:

f(x) = 2x

f(0) = 2 * 0 = 0

f(1) = 2 * 1 = 2

f(2) = 2 * 2 = 4

f(3) = 2 * 3 = 6

f(4) = 2 * 4 = 8

The complete table of the linear function f(x) = 2x for x = 0 to 4 is:

x     0   1    2   3  4  

f(x)  0   2   4   6   8

The function is given as:

f(x) = 2x

When x = 0, we have:

f(0) =2(0) = 1

When x = 1, we have:

f(1) =2(1) = 2

When x = 2, we have:

f(2) =2(2) = 4

When x = 3, we have:

f(3) =2(3) = 6

When x = 4, we have:

f(4) =2(4) = 8

So, the complete table is:

x     0   1    2   3  4  

f(x)  0   2   4   6   8

There are not any angles shown, and the triangle is not a right triangle, so it is SSS

Answer:fevagria un 30% de dinero

Step-by-step explanation:

Step-by-step explanation:

Evaluate:

-[-1⅘ ÷ 0.3(1.2)] - 5/6

⇛-[- 20/5 ÷ 0.3(1.2)]-5/6

⇛- [-20/5 ÷ 0.36] - 5/6

⇛-[-20/5 ÷ 36/100] - 5/6

Here I have changed in expression decimal point into fraction by putting 100 in Denominator.

⇛-[-20/5 × 100/36] - 5/6

⇛-[(-20 × 100)/(5×36)] - 5/6

⇛-[-2000/180]-5/6

Remember (-) × (-) = +.

⇛2000/180 - 5/6

Now, LCM of the denominator 6 and 180 is 180.

⇛(2000 - 150)/180

⇛1850/180

Now, reduce the fraction by extracting and cancaling out by 2.

⇛825/80

Again reduce the fraction by extracting and cancaling out by 5.

⇛165/16 Ans.
