i really need help! can someone help me

Answer:

816

Step-by-step explanation:

Find total number of people asked by adding all the people.

54 + 56 + 52 + 63 = 225

So, 54 out of 225 people have their favorite snack as brownies.

We need to find out how many it is for 3,400. We can do that by cross multiplying.

54      =     x        (did it like this so it's better visually)

225       3400

Multiply both sides by 3,400 and divide to get:

x = 816

Answer:

12

Step-by-step explanation:

Hint:  This should be n^2+2n−2=0.  The coefficients are a = 1, b = 2 and c = -2.

The discriminant is b^2 - 4ac = 4 - 4(1)(-2) = 12

Answer:

Convert   4.5% to a decimal. 6000,0.045, 8 years

Step-by-step explanation:

I used math--way

The value of the account after 8 years with continuous compounding is approximately $8593.76.

To find the value of the account after 8 years with continuous compounding, we can use the formula for continuous compounding:

A=P⋅e rt

Where:

A is the amount of money accumulated after

t years, including interest.

P is the principal amount (the initial amount of money).

r is the annual interest rate (in decimal).

t is the time the money is invested for, in years.

e is the base of the natural logarithm, approximately equal to 2.71828.

Given:

P=$6000

r=4.5%=0.045 (in decimal)

t=8 years

Substituting the values into the formula:

A=6000⋅e 0.045⋅8

Now, let's calculate this:

A=6000⋅e 0.36

A≈6000⋅2.71828 0.36

A≈6000⋅1.432292989

A≈8593.757934

Rounding to two decimal places, the value of the account after 8 years with continuous compounding is approximately $8593.76, which is slightly different from the provided answer of $8532.60. This discrepancy might be due to rounding differences or calculation variations.

Answer:

its B,C,and E

Step-by-step explanation:

Answer:

P(sum is even) = 1/16 + 9/16 = 10/16

= 5/8

P(sum is odd) = 3/8

E(x) = (5/8)(6) + (3/8)(-2) = 3

The mathematical expectation for the number of spaces moved in one turn is 3 spaces forward.

Answer:

it is ∠A corresponds to ∠A'.

∠A'AC' corresponds to ∠B.

CB corresponds to C'A.

and △ABC ~ △A'AC'.

Step-by-step explanation:

i just did it and got it right

All the options are correct.
∠A corresponds to ∠A'.
∠A'AC' corresponds to ∠B. CB corresponds to C'A.
Segment A'A is parallel to segment C'C.
△ABC ~ △A'AC'.

In congruent geometry, the shapes that are so identical. can be superimposed to themselves.

Since
The dilation DO,3 (x, y) → (3x, 3y)
its pre image of △ABC
if its pre image than the two triangle remains identical to all condition hence every condition in the option is true.

Answer:

Order is 6

Step-by-step explanation:

The population of Portland Oregon has recently grown to more than 500,000.

The order of magnitude for the number of people in Portland means the power of 10. It means that we need to write 500,000 in form of 10 to the power. So,

[tex]P=500,000[/tex]

It contains 6 zeroes. It means,

[tex]P=5\times 10^6[/tex]

So, the order of magnitude for the number of people in Portland is 6.

The correct answer is option (C) Standard Deviation.The estimator that consistently has a skewed sampling distribution is the standard deviation, especially when the original data is non-symmetric or skewed.

Among the given options, the estimator that will consistently have a skewed sampling distribution is the standard deviation. When estimating the standard deviation from a sample, the resulting distribution does not always follow a normal pattern, especially if the original data is skewed. The standard deviation is calculated using each data point's deviation from the mean, which can lead to skewed results in non-symmetric distributions.

For instance, in a skewed distribution with extreme values, the mean and subsequently the standard deviation can be disproportionately influenced by those extremities, hence failing to accurately reflect the spread of the majority of the data. Therefore, sometimes measures like the median, which is not as sensitive to outliers, are considered better representations of the central tendency in a skewed data set.

Additionally, the standard deviation is meaningful for symmetrical distributions, while skewed distributions require a consideration of other measures such as the modes, medians, or quartiles. When presented with data, always visualize it using a histogram or a box plot to better understand the distribution.

It's probably A (I can't tell you for certain, because I can't see the image, but the other options seem illogical).

The bar graph presents the number of students who received each letter grade on a written report, enabling a clear comparison of quantities.

The statement about the graph that is true: The bar graph displays the number of students who earned each letter grade on a written report, making it suitable for comparing quantities. For example, the bar that represents the number of students who received an A appears to be shorter than the bar for students who received a C, indicating fewer students got an A.

The average rate of change for a square root function decreases as we look at intervals of fixed lengths over the domain and the endpoints of those intervals increase. This is due to the property of the square root function where it's an increasing function but at a decreasing rate.

The average rate of change of a function measures how the output (y-value) changes in comparison to the input (x-value). For a square root function like f(x) = √x, as we look at intervals of fixed lengths over the domain and as the endpoints of those intervals increase, the average rate of change decreases.

This happens because the slope of the tangent line to the function (which represents the rate of change) gets progressively less steep as x increases. Square root functions are increasing functions but at a decreasing rate. For example, the slope between the points (1,1) and (4,2) on the function f(x) = √x is 1/3, but between (4,2) and (9,3), it's 1/5, indicating a decrease in the rate of change.
