How can you subtract mixed numbers when the fraction in the first mixed numbers is less than the fraction in the second mixed number?
When subtracting mixed numbers, if the fraction in the second mixed number is larger than the fraction in the first mixed number, rewrite the first mixed number by regrouping one whole as a fraction. Alternatively, rewrite all fractions as improper fractions and then subtract.

Answer:
-50
Step-by-step explanation:
Since the rate is -2 degrees per minute and you need to know what the temperature will be after 25 minutes, simply multiply the two numbers:
= -2 x 25
= -50
It will reach a temperature of -50 degrees after 25 minutes.

What is the probability that six consecutive integers will be chosen as the winning numbers in a lottery where each number chosen is an integer between 1 and 40 (inclusive)?
Answer:
0.00000911843
Step-by-step explanation:
Since the number chosen is an integer between 1 and 40 (inclusive), it means that the number of terms is 40.
Thus; n = 40
Probability that 6 integers (r = 6) which is number of possible outcomes will be gotten without repetition is gotten by the combination formula which is;
C(n, r) = n!/(r!(n - r)!)
C(40, 6) = 40!/(6!(40 - 6)!)
C(40,6) = 3838380
Now, to select 6 consecutive integers, it can be done in different combinations such as;
(1 - 6, 2 - 7, 8 - 13,...e.t.c)
Total number of favorable outcomes will be 35.
Now,probability that six consecutive integers will be chosen as the winning numbers is;
P(that six consecutive integers will be chosen as the winning numbers) = number of favorable outcomes/number of possible outcomes = 35/3838380 = 0.00000911843

Step-by-step explanation:
You can find the constant of proportionality of the ratio of the price to the number of bouquets from the table by dividing them. For example, it you divide 9 by 3 or 18 by 6, you get 3. Therefore, you know that every bouquet is 3 dollars. :) Hope this helps

what is the slope of this graph Algebra 1b
Which describes the correlation shown in the scatterplot?
Answer:
There is no positive or negative correlation
Step-by-step explanation:
the x-values are increasing but the y-values are staying the same so if you drew a line through correlation... the slope would be around 0
61. The 2003 Statistical Abstract of the United States reported the percentage of people 18 years of age and older who smoke. Suppose that a study designed to collect new data on smokers and nonsmokers uses a preliminary estimate of the proportion who smoke of .30. a. How large a sample should be taken to estimate the proportion of smokers in the population with a margin of error of .02
Answer: Required minimum sample size = 2017
Step-by-step explanation:
Formula : Sample size(n) for population proportion(p):
[tex]n= p(1-p)(\frac{Z^c}{E})^2[/tex] , where E = Margin of error
If p = proportion of smokers
Given: p =0.30 and E=0.02
[tex]z^c[/tex] for 95% confidence level = 1.96
So,
[tex]n=0.30(1-0.30)(\dfrac{1.96}{0.02})^2\\\=0.30(0.70)(98)^2\\\\=2016.84\approx2017[/tex]
Hence, required minimum sample size = 2017

The distance Train A travels is represented by d = 69t, where d is the distance in kilometers and t is the time in hours. The distance Train B travels at various times is shown in the table. What is the unit rate of each train? Which train is going faster?
If d is distance measured in km and t is time measured in hours, then d = 69t tells you that train A is moving at a rate of 69 km/h.
Why? If t = 1, then d is the distance it moves in 1 hour, and that's precisely the unit rate. It's the rate at which the distance changes when 1 unit of time passes.
For train B, use the info in the given table. In 1 hour (between hours 4 and 5), the train covers a distance of 375 km - 300 km = 75 km. So it's moving at a rate of 75 km/h.
It should be clear which train is faster.
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]d(A) = 69t[/tex]
[tex]d(B) = 75t[/tex]
The unit rate is the coefficient of t which is the slope of the line because the trains distance traveled equation are linear.
Thus :
Train A's unit rate is 69 km per hour.
And
Train B's unit rate is 75 km per hour.
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Train B is going faster because its unit rate is greater than Train A's unit rate .

Zachary purchased a computer for $1,500 on a payment plan. Six months after he purchased the computer, his balance was $600. Eight months after he purchased
the computer, his balance was $300. What is an equation that models the balance y after x months?
The equation models the balance y after x months
9514 1404 393
Answer:
y = 1500 -150x
Step-by-step explanation:
Apparently, we're to assume that the balance is linear function of the number of months. We are given 3 points:
(0, 1500), (6, 600), (8, 300)
Any two of these can be used to write the equation of the line using the 2-point form:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (600 -1500)/(6 -0)(x -0) +1500
y = -900/6x +1500
y = 1500 -150x . . . models the balance after x months

graph a straight line through coordinates (0, 5) and (1, 3) then shade above that line
Step-by-step explanation:
(0, 5) is the y-intercept 5 and then from that point you go down 2 units and right 1 unit which would leave you at coordinate (1, 3) then you shade above that line since y is more than that line (-2x + 5)

Alejandro bought $3.50 worth of pencils and erasers at the school store. Pencils cost $0.50 apiece, and erasers cost
$0.75 apiece. Which equation written in standard form represents the number of pencils, p, and the number of erasers,
e, that Alejandro bought?
O 0.75e = 3.50 -0.50p
O 0.50p + 0.75e = 3.50
O 3e = 14 -2p
O 2p + 3e = 14

A company places a seven-digit serial number on each part that is made. Each digit of the serial number can be any number from 0 through 9. Digits can be repeated in the serial number. How many different serial numbers are possible?
Answer: 10,000,000 different numbers are possible.
Step-by-step explanation:
Given: Serial number is of 7 digits.
Choices for digits = 10 (0 to 9)
If digits can be repeated, then by Fundamental principle of counting,
The different serial numbers are possible = [tex]10^7[/tex]
= 10,000,000
Hence, the different serial numbers are possible = 10,000,000
