The diameter of the Sun is approximately 1,392,000,000 meters. What is this length
expressed in scientific notation
Answer:
1392 x 10 m
Step-by-step explanation:
Answer:
1.392 x 10⁹ m
Step-by-step explanation:
when you put numbers in scientific notation, there is one (1) non-zero number before the decimal
1.392
now count how many place you would have to move the decimal to the right in order to make 1,392,000,000
9 place
this means your second half looks like x 10⁹
now put it all together
1.392 x 10⁹ m

Answer:
Dilation factor is 2 (two)
Step-by-step explanation:
The dilation factor that maps one triangle ABC to its image A'B'C' can be obtained by finding the relationship between the x and y coordinates of each image point to the original:
A' = (6, 2) when A is (3, 1)
We observe a factor of 2 in the two coordinates.
B' = (-4, 4) when B is (-2, 2) Also a factor of 2 (two)
Same for point C.

D=360-20-25-80=235
x=360-235=125
Answer:
BDC + ABD +ACD + BAC = 360
80 + 20 + 25 + BDC = 360
BDC + 125 = 360
BDC = 360-125
BDC = 235
Now,
BDC + x = 360
235 + x= 360
x = 360-235
x = 125

A bicycle path divides a rectangular park. The path makes a 42° angle with the top border of the park, so mZ1 = 42°. What is m/2? How do you know?
Answer: 0.5 meters because m=meters and meters/2 = 0.5
The required measure of the angle m∠2 is 138°.
Given that,
A bicycle path divides a rectangular park. The path makes a 42° angle with the top border of the park, so mZ1 = 42°. What is m/2 is to be determined.
The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.
Here,
According to the question,
Let the measure be x,
Now the bicycle path divides the rectangular park,
So,
m∠1 + m∠2 = 180
42 + x =180
x = 180 - 42
x = 138°
Thus, the required measure of the angle m∠2 is 138°.

The president of Doerman Distributors, Inc., believes that 30% of the firm's orders come from first-time customers. A random sample of 150 orders will be used to estimate the proportion of first-time customers.Required:a. Assume that the president is correct and p = 0.30. What is the sampling distribution of p bar for this study?b. What is the probability that the sample proportion p bar will be between 0.20 and 0.40?c. What is the probability that the sample proportion will be between 0.25 and 0.35?
Answer:
Step-by-step explanation:
p = .3
n = 150
p(bar ) = 1 - p = .7

P ( .2 <p<.4 ) = P [ (.2 - .3) / .037 < z < ( .4 - .3 ) / .037 ]
= P [ (-2.7 < z < +2.7 ]

= .993
c )
P ( .25 <p<.35 ) = P [ (.25 - .3) / .037 < z < ( .35 - .3 ) / .037 ]
= P [ (-1.35 < z < +1.35 ]
= .9115 - .0885

Hamid has gained weight. He now weights 88kg, which is 10% higher than his normal weight. What is Hamids normal weight
Let his normal weight = 100%
He is 10% more so he is 110%
Divide his weight now by 110% to find his normal weight.
88/1.1 = 80
His normal weight is 80 kg

In a regression analysis if SST = 4500 and SSE = 1575, then the coefficient of determination is:___________.A) 0.35B) 0.65C) 2.85D) 0.45
Answer:
B) 0.65
Step-by-step explanation:
In a regression analysis, the formula for the coefficient of determination (R²)=
1 - SSE/SST
SSE = Sum of squared of errors
SST = Total sum of squares
From the above question,
SST = 4500
SSE = 1575
Coefficient of determination (R²) = 1 - 1575/4500
= 1 - 0.35
= 0.65
Therefore, the coefficient of determination = 0.65
The coefficient of determination of the given parameter is (b) 0.65
The given parameters are:
[tex]SST = 4500[/tex] --- the total sum of squares
[tex]SSE = 1575[/tex] --- the sum of squares error
The coefficient of determination (R²) is calculated using the following formula
[tex]R^2 = \frac{SST - SSE}{SST}[/tex]
Substitute values for SST and SSE
[tex]R^2 = \frac{4500 - 1575}{4500}[/tex]
Simplify the numerator
[tex]R^2 = \frac{2925}{4500}[/tex]
Divide the fraction
[tex]R^2 = 0.65[/tex]
Hence, the coefficient of determination is (b) 0.65

The scale of a map says that 4 cm represents 5 km.What is the actual number of kilometers that is represented by 5 centimeters on the map?
Hey there! I'm happy to help!
We see that 4 cm represents 5 km. We want to see how much 5 cm represents.
To get from 4 cm to 5 cm, you multiply by 5/4. So, we multiply our 5 km by 5/4 to see how kilometers are represented by 5 centimeters on the mask.
5(5/4)=6 1/4
Therefore, the number of km represented by 5 cm on the map is 6 1/4 km.

Rufus collected 18 pounds of
aluminum cans to recycle. He
plans to collect an additional 2
pounds each week. He wants to
collect a total of 42 pounds of
aluminum cans. Let x represent
the number of weeks Rufus
collects aluminum cans.
Answer:
12
Step-by-step explanation:
collected can=18pound
total can to collect=42
collected can per week=2
now,
42-18 =24
so, remaining cans to collect is 24pound
and,
24/2
=12
so, Rufus have to collect for 12 weeks for 42pound of cans in total
