High blood pressure has been identified as a risk factor for heart attacks and strokes. The National Health and Nutrition Examination Survey reported that the proportion of U.S. adults with high blood pressure is 0.3. A sample of 38 U.S. adults is chosen. (a) Is it appropriate to use the normal approximation to find the probability that more than 40% of the people in the sample have high blood pressure? If so, find the probability. If not, explain why not. (b) A new sample of 80 adults is drawn. Find the probability that more than 40% of the people in this sample have high blood pressure. (c) Find the probability that the proportion of individuals in the sample of 80 who have high blood pressure is between 0.23 and 0.32.

Answer:

Area of circle = 28.28 unit²

Radius of circle from center point = 3 units

Diameter of given circle = 6 units

Circumference of circle = 18.85 unit

Step-by-step explanation:

Given:

Circle in third quadrant

Radius of circle from center point = 3 units

Diameter of a circle = 2 x Radius of circle

Diameter of given circle = 2 x Radius of circle from center point

Diameter of given circle = 2 x 3 units

Diameter of given circle = 6 units

Circumference of circle = 2πr

Circumference of circle = 2(22/7)(3)

Circumference of circle = 18.85 unit

Area of circle = πr²

Area of circle = (22/7)(3)²

Area of circle = 28.28 unit²

Answer:

C. 0.6

Step-by-step explanation:

If the probability of him passing is 0.4 then thats a 40% chance. But they're asking the probability of him failing so 100%-40%= 60%

60% = 0.6 in this scenario.

There is a 0.6 chance he will fail.

Answer:

Step-by-step explanation:

The eight in 6,084 is in the tenths place. Separately, it would be 80. The 8 in 9,821 is in the hundredths place. This one is worth 800. So the 8 in 9,821 is greater than the 8 in 6,084.

Answer:

yes

because it has length, side and base

Answer:

No

Step-by-step explanation:

If it is a right angled triangle, then it will satisfy the pythagoras theorem, which is as follows:

Perpendicular² + Base² = Hypotenuse²

{hypotenuse is the longest side in a right-angled triangle}

LHS : Perpendicular² + Base²

(15)² + (10)² = 225 + 100 = 325

RHS : Hypotenuse²

(17)² = 289

LHS ≠ RHS

Does not satisfy pythagoras theorem

So the triangle is not right angled

Answer:

y = 2x - 10

Step-by-step explanation:

y2 - y1/ x2 - x1

0 - 2 / 5 - 6

= 2

y = 2x + b

2 = 2(6) +b

2 = 12 + b

-10 = b

The equation is y = 2x - 10

Answer:

50 Degrees

Step-by-step explanation:

Since they already have 40 degrees for you, and a little square means a right angle (90 Degrees), then 40 + 90 is 130. The interior angles of a triangle always add up to 180, so 180 - 130 is 50. The answer is therefore 50 degrees.

Answer:

$20

Step-by-step explanation:

Kenny's gameplay: 1 month

Angie's gameplay: 3 months

1+3= 4

Kenny bought 1 software pack

Angie bought 2 software packs

1+2= 3

Each software package= $30

So 30×3= 90

Total cost= $170

170-90= 80

80÷4= $20

Answer:

C. six

Step-by-step explanation:

A hexagonal prism has 18 edges and a hexagonal pyramid has 12 edges, therefore the difference between the number of edges of the two solids is six (6) because 18-12 is 6.

The word "difference" infers that we need to subtract numbers in order to find how many are left.

Answer:

1 Answer. The chance of anding on A for one spin is 90+45360=38. So the probability of that happening twice in a row is 38×38=964.

Step-by-step explanation:

Answer: The two numbers are 10 and 12.

Step-by-step explanation:

Let the two consecutive numbers are x and x +2.

As per given, we have

[tex](x+2)+3x=42\\\\\Rightarrow\ 4x+2=42\\\\\Rightarrow\ 4x=40\\\\\Rightarrow\ x=10[/tex]

Smaller number = 10

Larger number = 10+2=12

Therefore, The two numbers are 10 and 12.

Answer:

I think that the answer might be 9.30 for the first one and the second one I think is 670.

Step-by-step explanation:

To find the area, you have to multiply the height and width for the two figures.

3.2 × 2.9 = 9.28

12 × 10 × 5.6 = 672

I think you round those to the nearest tenth. 9.28 would be 9.30 and 672 would be 670. I hope this answers your question.

Answer:

Quadrilateral MATH is a rectangle

Step-by-step explanation:

Prove quadrilateral MATH, M (-4,-1) A(-3,2). T(3, 0), H(2, -3) is a rectangle

A rectangle is a quadrilateral whose opposite sides have the same lengths and are parallel.

We solve the above question using the formula below to find the length of its sides

= √(x2 - x1)² + (y2 - y1)² when we are given vertices(x1, y1) and (x2, y2)

For side MA

M (-4,-1) A(-3,2)

√(-3 - (-4))² + (2 - (-1))²

= √1² + 3²

= √1 + 9

= √10 units

For side AT

A(-3,2). T(3, 0)

√(3 - (-3))² + (0 - 2)²

= √6² + -2²

= √36 + 4

= √ 40 units

For side TH

T(3, 0), H(2, -3)

√(2 - 3)² + (-3 - 0)²

√-1² + -3²

= √1 + 9

= √10 units

For side MH

M (-4,-1) H(2, -3)

√(2 - (-4))² + (-3 - (-1))²

= √6² + 2²

= √36 + 4

= √40 units

From the above calculation, we can see that

Side MA = Side TH = √10 units

Side AT = Side MH = √40 units

Opposite sides are parallel to each other, hence quadrilateral MATH is a rectangle
