Lexie started her homework at 4:30 P.M. She finished at 5:05 P.M. How many seconds did it take her to finish her homework?
Answer:
2100 seconds
Step-by-step explanation:
4:30 P.M. → 5:05 P.M. there are 35 minutes in between.
1 minute = 60 seconds
35 minutes × 60 seconds = 2100 seconds
The perimeter of a square piece of gold is 28 millimeters. How long is each side?
Answer:
7 millimeters
Step-by-step explanation:
Perimeter is the distance around an object.
The object is a square so all sides are equal. This means that we can do 28mm / 4 and get our answer of 7 millimeters.
(3,10) (5,-3) (7,4) (3, 8) is this a function
Answer:
no
Step-by-step explanation:
This is not a function
To be a function each x can only go to one y
x=3 goes to both y=10 and y=8
Not a function
This is the last one can somebody figure this out please?
Answer:
x = 8.4
Step-by-step explanation:
take 64 degree as reference angle
using cos rule
cos 64 = adjacent / hypotenuse
0.438 = 3.7 / x
x = 3.7 / 0.438
x = 8.44
x = 8.4

find the equation of the line show
Answer:
Equation : y = 2x + 3
Step-by-step explanation:
By considering any two coordinates from the line.
For example: I choose (0, 3) and (2, 7)
slope :
[tex]slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{7-3}{2-0} = \frac{4}{2} = 2[/tex]
Equation :
[tex](y - y_1) = m (x - x_1)\\\\(y - 7) = 2 (x - 2)\\\\y - 7 = 2x - 4\\\\y = 2x - 4 + 7 \\\\y = 2x + 3[/tex]
Grandma Gertrude’s Chocolates, a family owned business, has an opportunity to supply its product for distribution through a large coffee house chain. However, the coffee house chain has certain specifications regarding cacao content as it wishes to advertise the health benefits (antioxidants) of the chocolate products it sells. In order to determine the mean % cacao in its dark chocolate products, quality inspectors sample 30 pieces. They find a sample mean of 4% with a standard deviation of 2%. What is the margin of error at 90% confidence?
a. 1.49%
b. 1.24%
c. 0.62%
d. 0.75%
e. 1.36%
Answer:
c. 0.62%
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 30 - 1 = 29
90% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 29degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 1.6991
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}}[/tex]
Sample of 30, standard deviation of 2%.
Then
[tex]M = T\frac{s}{\sqrt{n}} = 1.6991\frac{2}{\sqrt{30}} = 0.62[/tex]
0.62%, so option c.
The numbers 24, 22, 34, 28, 29, 24, 25 29, a and b have a median of 27 and a mode of 29. Given that a
Answer: Median is 26,5 and modes are 24 and 29
Step-by-step explanation: In increasing order numbers are
22, 24 24, 25 , 28, 29 , 29 , 34. Because amount of number is even
median is (25 + 28) / 2 = 26,5 and modes are 24 and 29 because both
numbers exist twice
2 7/9 divided by 5/6 in fraction.
The fraction after the division is A = 46 / 15
What is a Fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given data ,
Let the first fraction be p = 2 7/9
Let the second fraction be q = 5/6
Now , A = p/q
On simplifying the equation , we get
A = 2 7/9 / 5/6
A = ( 25/9 ) / ( 5/6 )
A = ( 25/9 ) x ( 6/5 )
On simplifying , we get
A = 138/45
A = 46 / 15
Hence , the fraction is A = 46/15

A. A reflection across the y-axis, followed by a reflection across the x-axis.
B. A dilation of 2 followed by a dilation of 1.5
C. A translation right 2 followed by a translation up 2
D. A counterclockwise rotation of 360
Answer:
B
Step-by-step explanation:
a counter clockwiswe rotation of 360
A counterclockwise rotation of 360° maps an image onto itself.
What is a coordinate transformation?Suppose the initial coordinates are (x₁,x₂). We do 4 kinds of operations on the coordinates which include:
the translation which means to move the coordinate up and downdilation which means to expand or contract the length of the coordinate from the originrotation which means to rotate the coordinate about the origin counterclockwise or clockwise. The reflection which means to reflect the coordinate about the x-axis or y-axis.After doing these operations the final position of the coordinates is called the transformation of the initial coordinate.
How to solve it?On a counterclockwise rotation of 360 degree the coordinate comes back to the original position.

The random variable X is normally distributed with mean of 80 and variance of 36. The 67th percentile of the distribution is
Answer:
82.64
Step-by-step explanation:
Mean = 80 ; σ² = 36 ; σ = √36 = 6
Using the relation :
P(Z < x) = (x - mean) / standard deviation
P(Z < x) = 0.67
Z = invNorm(0.67) = 0.44
Hence,
0.44 = (x - 80) / 6
Cross multiply :
6 * 0.44 = x - 80
2.64 = x - 80
2.64 + 80 = x
82.64 = x
Hence, X = 82.64
