A normal distribution of data has a mean of 15 and a standard deviation of 4. How many standard deviations from the
mean is 25?
Answer:
25 is 2.5 standard deviations from the mean.
Step-by-step explanation:
Normal probability distribution
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean.
In this question:
Mean of 15 and a standard deviation of 4, so [tex]\mu = 15, \sigma = 4[/tex]
How many standard deviations from the mean is 25?
We have to find Z when [tex]X = 25[/tex]. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{25 - 15}{4}[/tex]
[tex]Z = 2.5[/tex]
So 25 is 2.5 standard deviations from the mean.

2.5

The average price for gasoline per gallon is $3.562 if last year the average price for gasoline per gallon was $2.810 what is the approximate percent of change
Answer: It increased by 78.89%
Step-by-step explanation:
2.810 / 3.562
=0.7889
78.89%
The approximate percent of change is 26.76% increase.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, The average price for gasoline per gallon is $3.562.
last year the average price for gasoline per gallon was $2.810.
∴ The net amount change is $(3.562 - 2.810) = $0.752.
Now to obtain percentage change we'll divide the net amount change by the original amount and multiply it by 100% which is,
= (0.752/2.810)×100%.
= 26.76% increase.

If the circumference of a circle is 4π cm, what is its area?
Find x & y so that quadrilateral is a parallelogram. (Look at image)
Answer:
x = - 6 y = 13
Step-by-step explanation:
we know when the diagonals bisect it divides into two equal parts so
-4x - 2 = -3x + 4
-4x + 3x = 4 + 2
- x = 6
x = - 6
Now
2y + 8 = 3y - 5
3y - 2y = 8 + 5
y = 13

Answer:
203 2/3
Step-by-step explanation:
Add all the wholes (55+55+46+46, that gets you 202), then, convert 2/3 to sixths (4/6). Then, add the fractions (4/6+4/6+1/6+1/6, that gets you 10/6, or 1 4/6). Now, our answer is 203 4/6, which can be simplified to 203 2/3.

What times what equals 6 but adds to -1
Answer: Nothing
Step-by-step explanation: There aren't any numbers that multiply to equal 6 but add to be -1.
There aren't any numbers that multiply to equal 6 but add to be -1 but we can say -6 and positive 1.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.A mathematical equation is a statement with two equal sides and an equal sign in between. example, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
For that , we need to try solving it first using the method of substitution in which we express one variable in other variable's form and then it can substitute this value in other equation to get linear equation in one variable.
We need to find the number that equals 6 but adds to -1.
We can see that there aren't any numbers that multiply to equal 6 but add to be -1.
So, we conclude that number could be -6 and positive 1.

Which congruence criteria can be used directly from the information about triangles HIJ and MNO to prove IJ¯¯¯¯¯¯≅MN¯¯¯¯¯¯¯¯¯¯ by CPCTC? HI¯¯¯¯¯¯¯≅NO¯¯¯¯¯¯¯¯, ∠I≅∠N, ∠H≅∠O (1 point) ASA congruence AAS congruence SAS congruence HL congruence
Answer: [tex]\overline{IJ}\cong \overline{MN}[/tex]
Step-by-step explanation:
Given: In triangle HIJ and triangle MNO we have
[tex]\overline{HI}\cong \overline{NO}, \angle{I}\cong \angle{N} ,\angle{H}\cong \angle{O}[/tex]
here, HI and NN are the included side between ∠I & ∠H and ∠N and ∠O.
So , by ASA congruence rule,
ΔHIJ ≅ ΔMNO
So by CPCTC (corresponding parts of the congruent triangles are congruent)
[tex]\overline{IJ}\cong \overline{MN}[/tex]
It was Sarah's job to fill her neighbor's bird feeders with sunflower seeds while they were on vacation.
She was given 12 cups of seeds to fill the 3 bird feeders. She filled the bird feeders for a whole week.
How many cups of seeds did Sarah put in each bird feeder each day?
Answer with a explanation
Answer:
The number of cups of seeds that Sarah put in each bird feeder each day is:
= 4/7 or 0.57 cups.
Step-by-step explanation:
a) Data and Calculations:
Number of cups of seeds = 12 cups
Number of bird feeders = 3
Therefore, each bird feeder will get 12/3 = 4 cups per week
In a week, there are 7 days.
This implies that each bird feeder will get 4/7 cups
This is equivalent to 0.57 cups for each bird feeder per day.
b) Sarah will be putting 4/7 cups of seeds in each bird feeder. When 4/7 is multiplied by 3 *7, we get a total of 12 cups, which represent the total number of cups of seed given initially to Sarah.
Answer:
The number of cups of seeds that Sarah put in each bird feeder each day is: = 4/7 or 0.57 cups.
