In the accompanying diagram of ABC ca is extended to D, m∠ABC = 70 and m∠BCA =50 Find m∠DAB
Answer:
120 degrees
Step-by-step explanation:
Find the diagram attached.
From the diagram;
Interior angles are m∠BCA and m∠ABC
Exterior angle is m∠DAB
The sum of interior angle of the triangle is equal to exterior
m∠BCA +m∠ABC =m∠DAB
Given
m∠ABC = 70
m∠BCA =50
m∠DAB = 70 + 50
m∠DAB = 120 degrees
Hence the measure of m∠DAB is 120 degrees

Jayden is driving to a concert and needs to pay for parking. There is an automatic fee
of $9 just to enter the parking lot, and when he leaves the lot, he will have to pay an
additional $3 for every hour he had his car in the lot. How much total money would
Jayden have to pay for parking if he left his car in the lot for 4 hours? How much
would Jayden have to pay if he left his car in the lot for t hours?
Answer:
1). $21
2). $9 + $3t
Step-by-step explanation:
1). 9+3(4)=a
9+12=a
a=21
2). 9+3(t)
9+3t
Total money would Jayden have to pay for parking after addition of automatic fee and additional fee is,
1. $21
2. $12
What is multiplication?The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the components that are multiplied are referred to as the factors.
Given that,
Jayden is driving to a concert and needs to pay for parking
There is an automatic fee of $9 just to enter the parking lot
when he leaves the lot, he will have to pay an additional $3 for every hour
Total money = ?
1. When he left the parking after 4 hours
Total money = automatic fee + additional fee
= 9 + (3×4)
= $21
2. When he left the parking after 1 hours
Total money = automatic fee + additional fee
= 9 + (3×1)
= $12
Hence, the fee is respectively for both the cases are $21, $12

XLiV represents 64 true ya false
Answer:
False
Step-by-step explanation:
Given
[tex]XLIV = 64[/tex]
Required
True or False
The above numeral can be split as follows:
[tex]XLIV = XL + IV[/tex]
X means 10 and L means 50.
But because X (10) which is smaller comes before L (50), XL is executed as:
[tex]XL = -10 + 50[/tex]
[tex]XL = 40[/tex]
In Roman numerals;
[tex]IV = 4[/tex]
Substitute 40 for XL and 4 for IV.
[tex]XLIV = 40 + 4[/tex]
[tex]XLIV = 44[/tex]
Hence;
[tex]XLIV = 64[/tex] is false
A construction zone on Interstate 15 has a speed limit of 40 mph. The speeds of vehicles passing through this construction zone are normally distributed with a mean of 44 mph and a standard deviation of 3 mph.
Required:
a. Find the percentage of vehicles who pass through this construction zone who are exceeding the posted speed limit.
b. What percentage of vehicles travel through this construction zone with speeds between 50 mph and 55 mph?
Answer:
a. The percentage of vehicles who pass through this construction zone who are exceeding the posted speed limit =90.82%
b. Percentage of vehicles travel through this construction zone with speeds between 50 mph and 55 mph= 2.28%
Step-by-step explanation:
We have to find
a) P(X>40)= 1- P(x=40)
Using the z statistic
Here
x= 40 mph
u= 44mph
σ= 3 mph
z=(40-44)/3=-1.33
From the z-table -1.67 = 0.9082
a) P(X>40)=
Probability exceeding the speed limit = 0.9082 = 90.82%
b) P(50<X<55)
Now
z1 = (50-44)/3 = 2
z2 = (55-44)/3= 3.67
Area for z>3.59 is almost equal to 1
From the z- table we get
P(55 < X < 60) = P((50-44)/3 < z < (55-44)/3)
= P(2 < z < 3.67)
= P(z<3.67) - P(z<2)
= 1 - 0.9772
= 0.0228
or 2.28%

Write an exponential function for each set of points.
(0 , 1024), (1,256), (2,64). (3 , 16) and (4 ,4)
Answer:
[tex]f(x)=(\frac{1}{4})^{x-b}[/tex]
Step-by-step explanation:
We are given that
(0,1024),(1,256),(2,64),(3,16)and(4,4)
From given data we assume an exponential function
[tex]f(x)=a^{b+x}[/tex]
where b and a are constant
[tex]f(0)=1024[/tex]
[tex]1024=a^b[/tex]...(1)
[tex]f(1)=256[/tex]
[tex]256=a^{b+1}[/tex]...(2)
Equation (1) divided by equation (2)
Then, we get
[tex]\frac{1024}{256}=\frac{a^{b}}{a^{b+1}}[/tex]
[tex]4=a^{-1}[/tex]
[tex]a=\frac{1}{4}[/tex]
Using the the value of a in equation (1)
[tex]1024=(\frac{1}{4})^{b}[/tex]
[tex]4^{5}=4^{-b}[/tex]
[tex]-b=5[/tex]
[tex]b=-5[/tex]
Therefore, the exponential function
[tex]f(x)=(\frac{1}{4})^{x-b}[/tex]

Answer:
2/6 and 4/12
Step-by-step explanation:
When you reduce both of these fractions, they come out to 1/3.
Dividing both terms of 2/6 by 2, the greatest common factor (GCF), would equal 1/3.
And dividing both terms of 4/12 by 4, which is the GCF in this case, would equal 1/3.

Consider a situation in which sampling without replacement is used to generate a random sample from each of two separate populations. To calculate a confidence interval to estimate the difference between population proportions, which of the following checks must be made?
Answer:
Each population must be at least 10 times as large as its corresponding sample.
Step-by-step explanation:
The 10 percent rule checks that the sample is small relative to the population (that is, that the population is at least 10 times as large as the sample size) so that independence of observations within a sample is reasonable to assume.
The check that must be made is (b) Both population must be approximately normal
From the question, we have the following highlights
The sampling is without replacementThere are separate populationsWhen the above highlights are true, then the population where the samples are to be selected must be approximately normal
Hence, the check that must be made is (b) Both population must be approximately normal

Answer:
d. x = 45°, y = 13.1√2
Step-by-step explanation:
Due to it being a square, each corner is 90°. The angle bisector splits the square into two triangles. These triangles are 45° 45° 90° triangles.
Half of 90° is 45°, therefore x = 45°.
When you have a 45° 45° 90° triangle, the legs of the triangle will equal each other and the hypotenuse will be the side length multiplied by √2. Therefore, y = 13.1√2.
