Answer:
126
Step-by-step explanation:
If n represents the original number, we have
(35%)n = 98
(80%)n = 224
We want to find (45%)n.
(45%)n = (80% -35%)n = (80%)n -(35%)n
(45%)n = 224 -98 = 126
45% of the number is 126.

A blue whale is swimming at an average rate of 3 miles per hour.
Write a linear equation that gives the distance y in miles that the whale swims in x hours.
Answer:
y = 3x
Step-by-step explanation:
you can use the equation to determine how many miles the whale swims in any desired hour
example, if you want to know how far it swims in 5 1/2 hours then just plug 5 1/2 in for 'x' and solve for 'y'
y = 3(5.5)
y = 16.5
whale travels 16.5 miles when going at a rate of 3 mph

Select one:
c=6.25+0.15w
c=6.25−0.15w
c=6.25+15w
c=15+6.25w

Say that a supplier claims they are 99% confident that their products will be in the interval of 50.02 to 50.38. You take samples and find that the 99% confidence interval of what they are sending is 50.01 to 50.39. What conclusion can be made
Answer:
The supplier becomes less accurate than they otherwise would have tried to claim. A further explanation is below.
Step-by-step explanation:
According to the provider, this same width of that same confidence interval would be as follows:
= [tex]50.38 - 50.02[/tex]
= [tex]0.36[/tex]
Depending on the input observed, the width including its confidence interval would be as follows:
= [tex]50.39 - 50.01[/tex]
= [tex]0.38[/tex]
As even the width of that interval again for survey asserted > the width including its confidence interval according to the provider's statement, we could conclude that such is the appropriate reaction.

Answer:
[tex]\boxed {\sf Equation: 60 \textdegree +4x= 180 \textdegree} \\[/tex]
[tex]\boxed {\sf x=30}[/tex]
Step-by-step explanation:
The interior angles of a triangle must add to 180 degrees.
In this triangle, the angles are A, B , and C. So,
∠A + ∠B + ∠C= 180°∠A is 60 degrees, ∠B is 3x, and ∠C is x. We can substitute the values in.
60°+3x+x=180°This is the equation we can use to find the value of x.
We also have like terms: 3x and x that can be combined.
60° + (3x+x)= 180° 60° + 4x=180°We can use the equation to solve for x. We have to isolate the variable.
60 is being added to 4x. The inverse of addition is subtraction. Subtract 60 from both sides of the equation.
60°-60°+4x=180°-60°4x= 180°-60°4x=120°x is being multiplied by 4. The inverse of multiplication is division. Divide both sides by 4.
4x/4= 120°/4x= 120°/4 x=30For the requirements of a report Suzy has to write for school, she has a choice of wide-rule or narrow-rule paper and three different pen colors in which to write the report. How many different possibilities does Suzy have to write the report? Enter a numerical answer only.
Answer:
6
Step-by-step explanation:
You first have to choose from Wide and Narrow.
Let's call them W and N
Then you have to choose 3 different pen colors.
Let call them, 1, 2, 3
So There are two choices from W and N.
Then we pick the number: 1, 2, 3.
so If you pick W, you will have 3 choices. Same for N.
So in total: 6 choices.
W= 3 choices, W1, W2, W3
N= 3 choices, N1, N2, N3
so 6 in total.

O A. y+2 = (x-1)
O B. y-2 = (x-1)
O C. y-2 = }(x+1)
O D.y+2 = (x+1)
Answer:
y-2=3/2(x+1)
Step-by-step explanation:
y-y1=m(x-x1)
y-2=3/2(x-(-1))
y-2=3/2(x+1)
uppose you have purchased a filling machine for candy bags that is supposed to fill each bag with 16 oz of candy. Assume that the weights of filled bags are approximately normally distributed. A random sample of 10 bags yields the following data (in oz): 15.87, 16.02, 15.78, 15.83, 15.69, 15.81, 16.04, 15.81, 15.92, 16.10 On the basis of this data, can you conclude that the mean fill weight is actually less than 16 oz? Let LaTeX: \alpha=5\%α = 5 %. What would be the appropriate null and alternative hypothesis?
Answer:
Null, H0: μ ≥ 16
Alternative ; H1: μ < 16
reject H0
Step-by-step explanation:
Null, H0: μ ≥ 16
Alternative ; H1: μ < 16
To compute the test statistic :
We need the sample mean and sample standard deviation :
15.87, 16.02, 15.78, 15.83, 15.69, 15.81, 16.04, 15.81, 15.92, 16.10
Using calculator :
Sample mean, m = 15.887
Standard deviation = 0.13
Test statistic :
(m - μ) / s/sqrt(n)
(15.887 - 16) / 0.13/sqrt(10)
-0.113 / 0.0411096
= - 2.749
Tcritical at 95%
Tn-1, 0.025
T10,0.025 = 2.262
Since the test statistic value is less than the critical value, reject H0

second. Find the numbers.
9514 1404 393
Answer:
the numbers are -10 and -11
Step-by-step explanation:
Let x represent the second number. Then the first number is x+1, and the relation can be written ...
5(x+1) = 4x -6
x = -11 . . . . . . . . subtract 4x+5
The first number is -10; the second number -11.

At TopHill elementary school, 84% of the students are driven to school every morning. The student population is 450. What is the number of students who are not driven to school?
Answer:
72 students were not driven to school
Step-by-step explanation:
First find the amount if students that got driven to school
84 percent *450
= (84:100)*450
= (84*450):100
37800:100 = 378
So 378 are driven to school
Subtract that from the total amount to get the amount who didn't get driven to school
450 - 378 = 72
72 student were not driven to school
