This is the floor of isaac's kitchen. Isaac needs to determine the area of the floor so he can order new tile. Enter the area, in square feet, of Isaac’s kitchen floor.
Answers
Answer:
134
Step-by-step explanation:
first, separate the floor into 3 different rectagles to calculate the area and then add them together.
area of rec=L*B
rec 1: 9.5*7=66.5
rec 2: (10.5-4.5)*(14.5-5-7)=15
rec 3:5*10.5=52.5
Then:
66.5+52.5+15=134

Answers
Answer:
[tex] \displaystyle y = - x + 2[/tex]
[tex]y = - x +1[/tex]
Step-by-step explanation:
we are given a vertex of a square i.e (1,1)
and the equations of the two parallel sides
notice that, the given vertex coordinates satisfy one of the parallel side i.e y=x which means that (1,1) points lie on one of Parallel sides
remember that,
every angles of a square is 90°
therefore,
we need to figure out the remaining Perpendicular line of the given Parallel sides so
let's figure out the perpendicular line of y=x line
recall that,
Parallel lines have the same slope thus
[tex] \displaystyle m_{ \rm perpedicular} = - 1[/tex]
since we are given a vertex the equation of the perpendicular line should be
[tex] \displaystyle y - 1 = - 1(x - 1)[/tex]
distribute:
[tex] \displaystyle y - 1 = - x + 1[/tex]
add 1 to both sides:
[tex] \displaystyle y = - x + 2[/tex]
to figure out the second perpendicular line we can consider the coordinates (0.5,0.5) of y=x equation
so the slope of the perpendicular line is -1
and the equation:
[tex]y - 0.5 = - 1(x - 0.5)[/tex]
distribute:
[tex]y - 0.5 = - x +0 .5[/tex]
add 0.5 to both sides:
[tex]y = - x +1[/tex]
and we are done!

3,500 grams
PLEASE ANSWER PLEASE
Answers
Given:
The package weighed 350,000 centigrams.
To find:
The conversions that are equivalent to 350,000 centigrams
Solution:
We know that,
1 centigrams (cg) = 0.000001 kilograms (kg)
1 cg = 0.1 decigrams (dg)
1 cg = 0.001 dekagrams (dag)
1 cg = 0.01 grams (g)
Using these conversions, we get
350,000 centigrams = 3.5 kilograms
350,000 centigrams = 35,000 decigrams
350,000 centigrams = 350 dekagrams
350,000 centigrams = 3,500 grams

Step-by-step explanation:
Given
[tex]Range = 60[/tex]
[tex]Min = 5[/tex]
[tex]Max = 65[/tex]
[tex]\bar x = 42.31[/tex]
[tex]\sigma^2 =100.00[/tex]
[tex]\sigma = 10.00[/tex]
[tex]\sum = 1227[/tex]
[tex]n=40[/tex]
Required
The t statistic
This is calculated using:
[tex]t = \frac{\bar x - \mu}{\sigma/\sqrt n}[/tex]
Where
[tex]\mu \to[/tex] Population mean
[tex]\mu = \frac{\sum }{n}[/tex]
[tex]\sum = 1227[/tex] and [tex]n=40[/tex]
[tex]\mu = \frac{1227}{40}[/tex]
[tex]\mu = 30.675[/tex]
So, we have:
[tex]t = \frac{\bar x - \mu}{\sigma/\sqrt n}[/tex]
[tex]t = \frac{42.31 - 30.675}{10/\sqrt{40}}[/tex]
[tex]t = \frac{42.31 - 30.675}{10/6.325}[/tex]

We know that the length of time required for a student to complete a particular aptitude test has a normal distribution with a mean of 41.0 minutes and a variance of 3.4 minutes. What is the probability, rounded to four decimal places, that a given student will complete the test in more than 35 minutes but less than 43 minutes?
Answers
Answer:
0.6832 = 68.32% probability that a given student will complete the test in more than 35 minutes but less than 43 minutes
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score 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. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 41.0 minutes and a variance of 3.4 minutes.
This means that [tex]\mu = 41, \sigma = 3.4[/tex]
What is the probability, rounded to four decimal places, that a given student will complete the test in more than 35 minutes but less than 43 minutes?
This is the p-value of Z when X = 43 subtracted by the p-value of Z when X = 35.
X = 43
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{43 - 41}{3.4}[/tex]
[tex]Z = 0.59[/tex]
[tex]Z = 0.59[/tex] has a p-value of 0.7224
X = 35
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{35 - 41}{3.4}[/tex]
[tex]Z = -1.76[/tex]
[tex]Z = -1.76[/tex] has a p-value of 0.0392
0.7224 - 0.0392 = 0.6832
0.6832 = 68.32% probability that a given student will complete the test in more than 35 minutes but less than 43 minutes

In order to determine the average commute of college students, a researcher gathers data from a group of 50 students at the local college. This sample yieldied a mean of 14 and a standard deviation of 1.9.
Required:
Construct a 90% confidence interval for the population mean from the provided data.
Answers
Answer:
13.5579875<x<14.44201244
Step-by-step explanation:
The formula for calculating the confidence interval is expressed as:
CI = x+/- z × s/\sqrt{n}
x us the mean = 14
Z is the 90% CI = 1.645
S is the standard deviation = 1.9
n is the sample size = 50
Substitute.
CI = 14+/-1.645×1.9/7.07106.
CI = 14+/-1.645×0.26870057
CI = (14-0.44201244, 14+0.44201244)
CI = 13.5579875, 14.44201244
Hence the required interval is 13.5579875<x<14.44201244

Answer:

Step-by-step explanation:
Midpoint formula
The midpoint of the line segment is given by M ( 4 , 3 )
What is the midpoint of two points?The midpoint of a line segment is a point that lies halfway between 2 points. The midpoint is the same distance from each endpoint.
Measure the distance between the two end points, and divide by 2.
Let A ( x₁ , y₁ ) be the first point
Let B ( x₂ , y₂ ) be the second point
The midpoint between A and B is M ( a , b ) where
a = ( x₁ + x₂ )/2
b = ( y₁ + y₂ ) / 2
Given data ,
Let the first point be A ( -2 , 3 )
Let the second point be B ( 10 , 3 )
Now , let the midpoint of A and B be M ( a , b ) where
a = ( x₁ + x₂ )/2
b = ( y₁ + y₂ ) / 2
On simplifying , we get
a = ( 10 - 2 ) / 2
b = ( 3 + 3 ) / 2
On further simplification , we get
a = 4
b = 3
Hence , the midpoint is M ( 4 , 3 )
