The Graph Below Shows Three Different Normal Distributions Which Statement Must Be True

Answers

Answer 1

Answer:

4th option is correct; Each distribution has a different mean and a different standard deviation

Step-by-step explanation:

For the mean to be same in all three distributions, all graphs must be centered around the same number, so mean is not same.

The width of each graph shows how much data deviate from the mean. Since the width is different in all three distributions, standard deviation is different in all three distributions

Which measure of central tendency is least appropriate for describing the given data set?

6, 6, 6, 7, 8, 8, 29

mode
median
mean

Answers

Answer: Third option is correct.

Step-by-step explanation:

Since we have given that

6, 6, 6, 7, 8, 8, 29

We will calculate the measures of central tendency:

1) Mode - the most occurring element in the data set.

So, Mode = 6

2) Median - the middle value of organised data set

So, Median = 7

3) Mean - the average of all data set

So, Mean = [tex]\dfrac{6+6+6+7+8+8+29}{7}=\dfrac{70}{7}=10[/tex]

So, we can see that Mode and Median are giving the closest value to each other, whereas Mean is giving the farthest value as compared to rest.

Hence, Mean is the least appropriate for describing the given data set.

Thus, Third option is correct.

what is the absolute value of 1.7​

Answers

Answer:

|1.7| = 1.7

Step-by-step explanation:

Definition of absolute value:

|a| = a if a ≥ 0

|a| = -a if a < 0

Examples:

|2| = 2

|-2| = -(-2) = 2

|0.45| = 0.45

|-0.45| = -(-0.45) = 0.45

|1000| = 1000

|-1000| = 1000

Therefore

|1.7| = 1.7

What is a1 for the geometric sequence for which a8= -3584 and a3 = 112 ?

Answers

Answer:

The first term is 28.

Step-by-step explanation:

Given: 8th term of Geometric sequence , [tex]a_8=-3584[/tex]

and 3rd term of Geometric Sequence, [tex]a_3=112[/tex]

We have to find First term of given geometric Sequence.

Let a be the first term of geometric sequence.

We know that,

[tex]a_n=ar^{n-1}[/tex]

So,

[tex]\frac{a_8}{a_3}=\frac{ar^{8-1}}{ar^{3-1}}=\frac{-3584}{112}[/tex]

[tex]\frac{r^{7}}{r^{2}}=-32[/tex]

[tex]r^5=-32[/tex]

[tex]r=-2[/tex]

So, [tex]a_3=112[/tex]

[tex]a\times(-2)^{2}=112[/tex]

[tex]a=\frac{112}{4}=28[/tex]

Therefore, The first term is 28.

What is the rate of increase for the function f(x)= 1/3 (^3 √24)^2x

Answers

Answer

You need to simplify the function first until the exponent turns into a plain x. Step 1 Leave 1/3 alone that is the a value, initial value. You are looking for the base

Step 2 Deal with the parenthesis. Factor 24 and you will get 2 and the cube of 3. 

Step 3 Separate the exponent (2) (x)

Step 4 Now square each term inside the parenthesis

2 squared and cube of 3 square  the 2^2 will be 4, the other expression means  cube of 3 times cube of 3 and that's cube of 9

Step 5 Your base should be (4 cube of 9)

f'(x) = C, indicating a constant rate of increase.

The function given is f(x) = (1/3) * ((³√24)²) * x.

To find the rate of increase (or the derivative of this function), we need to rewrite the function in a simpler form. Firstly, simplify the constant:

(1/3) * ((³√24)²) * x can be simplified as a single constant C.

Let's break it down:

³√24 = 24¹/³, so (³√24)² = (24¹/³)² = 24²/³.

Next, we multiply this by 1/3:

C = (1/3) * 24²/³

Now the function becomes:

f(x) = C * x

This is a linear function where C is a constant coefficient. Therefore, the rate of increase (or the derivative) of f(x) with respect to x is just the constant C.

We then find the derivative:

f'(x) = C

As there are no x terms left, the rate of increase is constant and equal to C, which is (1/3)*24²/³.

A rectangular prism has a length of 5 1/8 feet, a width of 7 1/2 feet, and a height of 2 feet. What is the volume of the prism? Enter your answer in the box. ft³

Answers

For this case we have that by definition, the volume of a rectangular prism is given by:

[tex]V = A_ {b} * h[/tex]

Where:

[tex]A_ {b}:[/tex] It is the area of the base

h: It's the height

According to the data we have:

[tex]length = 5 \frac {1} {8} = \frac {8 * 5 + 1} {8} = \frac {41} {8}[/tex]

[tex]width = 7 \frac {1} {2} = \frac {2 * 7 + 1} {2} = \frac {15} {2}[/tex]

The number of bacteria in a petri dish doubles
each hour. There were initially 300 bacteria in the
dish. When the scientist checked again there were
4,800 bacteria. How much time passed?

Answers

Answer:

4 hours

Step-by-step explanation:

The exponential growth equation is given by

y = a (b)^(x)

where a is the initial value, b is the growth rate and x is the time from the initial value

We know the initial value is 300 and the growth rate is 2

y = 300 (2)^(x)

We want to know the time when we have 4800 bacteria

4800=300 *2^(x)

Divide each side by 300

4800/300 = 300/300 * 2^(x)

16 = 2^(x)

Rewrite 16 as a power of 2

2^4 = 2^(x)

x=4

It will take 4 hours

Jade can buy a maximum of 6 magazines or 2 pies with her $24 weekly budget. The slope of her budget constraint is -2, representing the trade-off between pies and magazines. The opportunity cost of purchasing a pie is 3 magazines.

Jade has a weekly budget of $24, which she allocates between magazines and pies. Let's address the questions one by one:

Magazines: If the price of a magazine is $4 each, Jade can buy 6 magazines in a week since $24 divided by $4 equals 6.Pies: If the price of a pie is $12, Jade can purchase 2 pies in a week, as $24 divided by $12 equals 2.Budget constraint: On a graph with pies on the horizontal axis and magazines on the vertical axis, Jade's budget constraint would be a straight line starting at 6 magazines (if she buys 0 pies) and ending at 2 pies (if she buys 0 magazines). The slope of this budget constraint is -2 (the price of a pie divided by the price of a magazine).Opportunity cost: The opportunity cost of purchasing one pie is the number of magazines she has to give up, which is 3 magazines ($12/$4).

At 10:00 AM a truck started traveling from point A with a speed of 40mph. 3 hours and 10 minutes later a car started to drive from point A in the same direction with an average speed of 60mph. At what time will the car catch up with the truck?

Answers

Answer:

12:07 pm

Step-by-step explanation:

The question is on relative speed

Calculate the distance covered by truck after 3hours and 10 minutes

Given; speed of truck= 40mph

Time the truck took to travel before the car started to drive from point A= 3h 10 minutes

Change hours to minutes= (60×3) + 10 = 190 minutes

Formulae for speed, S=d/t where S is speed of truck, d is distance covered and t is time

if S=d/t then distance d=S×t

d= 40×190/60 =380/3 =126.67 miles

Finding the time the car catch up with the truck

t=d/S where d=126.67 miles and speed of car = 60mph

t= 126.67/60 = 2.11 hours

Change hours to minutes

1 hr=60minutes

2.11 hrs= 2.11×60=126.67 minutes⇒2hrs and 6.67 minutes

t⇒2 hrs 7minutes

Add to the departure  time

10.00 + 2: 07 = 12:07 pm

Please help! Select the correct ordered pairs in the table.

Answers

Answer:

(-4, -12) (1, -2) (2, -18)

Step-by-step explanation:

We have a grade 3 polymial function.

We know that the function has a minimum at the point

(-3, -18).

If this is the minimum of the function then this means that when  [tex]x <-3[/tex]  the function is decreasing and when  [tex]x> -3[/tex]  the function is growing.

Look in the table for ordered pairs with values of x less than -3.

The only point is (-4, -12).

Then the function has a maximum in  ([tex]\frac{1}{3}[/tex], [tex]\frac{14}{27}[/tex])

This means that when  [tex]x> \frac{1}{3}[/tex]  the function is decreasing and when  [tex]x< \frac{1}{3}[/tex]  the function is growing.

Search the table for ordered pairs with values of x greater than [tex]\frac{1}{3}[/tex]

We have

Finally the ordered pairs in which the function decreases are:

(-4, -12) (1, -2) (2, -18)

1Kg of grapes cost 5.80 Meagan buys 700 grames of grapes how much does she pay

Answers

Meagan pay 4.60

Step-by-step explanation:

1kg------5.80

700g----X

700x5.80=4.60/1=4.60

Final answer:

To find the cost of 700 grams of grapes, divide the cost of 1 kilogram by 1000 to get the price per gram, then multiply by 700. Meagan pays $4.06 for 700 grams of grapes.

Explanation:

To calculate how much Meagan pays for 700 grams of grapes when 1 kilogram (1000 grams) of grapes costs $5.80, we first find out the cost per gram. Then we multiply the cost per gram by the amount of grams Meagan is buying.

The cost per gram is: $5.80 / 1000 grams = $0.0058 per gram.

So for 700 grams, Meagan pays: $0.0058 per gram × 700 grams = $4.06.

Therefore, the cost of 700 grams of grapes is $4.06.

pLEASE HELP! If z varies inversely as w, and z=5 when w=8, find z when w=10

Answers

z=4. If z varies inversely as w, and z=5 when w=8, then when w=10 the value of z is 4.

This exercise is an example of  reverse proportionality, Two magnitudes a and b are inversely proportional when there is a constant k such that

a⋅b=k, where constant k is called the proportionality constant.

Then if z varies inversely as w, and z=5 when w=8

z.w=k -------> 5.8=k -------> k=40

So, let's find z when w = 10. With k = 40

z.w=K, clear z from the equation

z=k/w -------> z=40/10 -----> z=4

Final answer:

To find z when w = 10 in an inverse variation equation, we can use the equation z = k/w. By substituting the given values and solving for the constant of variation, we find that when w = 10, z = 4.

Explanation:

To find the value of z when w is 10, we need to use the inverse variation equation. Inverse variation is represented by the equation z = k/w, where k is the constant of variation.

Given that z = 5 when w = 8, we can substitute these values into the equation to find k. 5 = k/8. Solving for k, we get k = 40.

Now, we can substitute the value of k and w = 10 into the equation z = k/w. z = 40/10 = 4. Therefore, when w = 10, z = 4.
