The population standard deviation for the heights of dogs, in inches, in a city is 7.5 inches. If we want to be 90% confident that the sample mean is within 2 inches of the true population mean, what is the minimum sample size that can be taken

Answer:

From smallest to largest 1/4, 1/3,1/2

Step-by-step explanation:

As the data suggests: 1/4 would be the smallest, 1/3 is in the middle, and 1/2 is the largest sum.

1/4 = 0.25

1/3 ≈ 0.33

1/2 = 0.5

The fractions in order of size, smallest to largest, 1/4, 1/3, 1/2

Used the concept of ascending order that states,

Ascending order is a method of arranging numbers from smallest value to largest value. The order goes from left to right.

The numbers arranged in order from least to the greatest number is called Ascending order.

Given that,

The fraction is,

1/4, 1/2, 1/3

Now evaluate the fractions as

1/4 = 0.25

1/2 = 0.5

1/3 = 0.33

After arranging the number into ascending order, we get;

0.25, 0.33, 0.5

Or, 1/4, 1/3, 1/2

Therefore, the fractions in order of size, smallest to largest is,

1/4, 1/3, 1/2

The slope for this graph will be 2

Answer:

2

Step-by-step explanation:

you use the rise over run formula. as you can see, the line hits certain points. You count how many points it is above and over, and that is 2 over 1. Remember, lines always go from left to right, so if it goes diagonal downward, it's a negative slope.

No.

When you divide by a positive value you do not flip the inequality, only when dividing by a negative value.

2x < -6

To solve for c you divide both sides by 2, which is a positive value so the inequality stays the same:

X < -6/2

X < -3

Answer:

20% 153.6 11111111111111111111111111111111

The amount of meters left is  0.144 meters

First and foremost, it should be noted that: 1 yard = 0.9144 meter

Therefore, 10 yards to meters will be:

= 0.9144 × 10

= 9.144 meters

Since Allison uses 9 meters, the amount of thread that is left on the

spool will be:

= 9.144 meters - 9 meters

= 0.144 meters

Answer:

x = 15/2 (15 over 2)

y = 8

Step-by-step explanation:

there 3 different way to do this (substitution, Elimination and Matrix)

ill be showing substitution ( you use the answer of one of the variables and substitute it for the other questions variable)

4 + y = 12

y = 12 -4

y = 8

y = -2x - 7

8 = 2x - 7  

8 + 7 = 2x

15 = 2x

x = 15/2

Answer: fourth option (3² × 5)

Step-by-step explanation: The prime factorization of 135 is (3² × 5) because:

3 x 3 x 3 = 27

27 x 5 = 135

The answer to the question is (3² × 5).

Answer:

3^3 × 5 [Fourth option, bottom one]

Step-by-step explanation:

First, 3^2 × 5^2 cannot be correct because although 3, and 5 are prime numbers 3^2 × 5^2 ≠ 135 as 3^2 × 5^2 = 225.

Second, 3 × 5 × 9 can't be right because although 3 × 5 × 9 = 135, 9 is not a prime number.

Third, 3 × 5^3 is not correct because although 3 and 5 are prime numbers, 3 × 5^3 ≠ 135 as 3 × 5^3 = 375.

The last question must be correct because it is the only remaining choice answer. Plus 3 and 5 are both prime numbers, and 3^3 × 5 = 135, 3^3 × 5 = 3 × 3 × 3 × 5 = 27 × 5 = 135.

Step-by-step explanation:

Let X represents the test results for a class that follow a normal distribution .

Given: Mean [tex]\mu=78[/tex], Standard deviation  [tex]\sigma=36[/tex]

Then, the probability that it is greater than 84 will be

[tex]P(X>84)=P(\dfrac{X-\mu}{\sigma}>\dfrac{84-78}{36})\\\\=P(Z>0.167)\ \ \ [Z=\dfrac{X-\mu}{\sigma}]\\\\=1-P(Z<0.167)\\\\=1-0.5663=0.4337\ [\text{By p-value table}][/tex]

Hence, the required probability = 0.4337

Answer:

y = -7x - 13

Step-by-step explanation:

When graphing a great website to use is desmos graphing calculator. In it I put in the equation you gave me and the point (-1,-6). When making a parallel equation it should have the same slope as the original problem, so -7. I then set up the equation for y = -7x, since that is what the know and put in numbers to the y-intercept till it matched up with the dot. Making the equation y = -7x - 13

Answer:

So there are two answers.

Step-by-step explanation:

One answer is vertical strech which streches it vertically and that equation would be f(x)= -4x^2+3 (this is also reflected across the x-axis)

The other answer is if you want a vertical compression and that equation would be f(x)= -1/4x^2+3 (also reflected across the x-axis)

Answer:

328

Step-by-step explanation:

For these questions we need to use BODMAS method

B - Brackets

O - Power

D - Division

M - Multiplication

A - Addition

S - Subtraction

First we need to see if there are any brackets

(4 + 3) = 7

After that we need to find if there is any power

- No power

After that we need to find if there is either multiplication or division

23 x 2 = 46

46 x (4 + 3) = 46 x 7 = 322

Now we need to simplify so , we don't get confused

23 x 2 x (4 + 3) x 20 = 322

322 + 6 = 328

We have simplified the answer as much as we can

Answer = 328
