Factor completely and then place the factors in the proper location on the grid. 25a 2 - 30a + 9

Answers

Answer:

(5a−3)^2

Step-by-step explanation:

25a^2 - 30a + 9

Factor the expression by grouping. First, the expression needs to be rewritten as 25a^2+pa+qa+9. To find p and q, set up a system to be solved.

p+q=−30

pq=25×9=225

Since pq is positive, p and q have the same sign. Since p+q is negative, p and q are both negative. List all such integer pairs that give product 225.

−1,−225

−3,−75

−5,−45

−9,−25

−15,−15

Calculate the sum for each pair.

−1−225=−226

−3−75=−78

−5−45=−50

−9−25=−34

−15−15=−30

The solution is the pair that gives sum −30.

p=−15

q=−15

Rewrite 25a^2 - 30a + 9 as (25a^2−15a)+(−15a+9).

(25a^2−15a)+(−15a+9)

Factor out 5a in the first and −3 in the second group.

5a(5a−3)−3(5a−3)

Factor out common term 5a−3 by using distributive property.

(5a−3)(5a−3)

Rewrite as a binomial square.

if a state issued license plates using the scheme of one letter followed by five digits, how many plates could it use

Answers

Answer:

786240 different license plates.

Step-by-step explanation:

The required number of plates that can be used is 2,599,974.

Given that,
State-issued license plates use the scheme of one letter followed by five digits, how many plates could it used is to be determined.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Maxium five-digit number = 99999
Total letters = 26
Number of plates = 26 × 99999 = 2,599,974

Thus, the required number of plates that can be used is 2,599,974.

So subtract 12 from 28

28-12

=16

18. The kittens can be

3.4, 3.3, 3.2, 3.1, 3, etc. ( units in ounces)

There are a lot of combinations so you have to find out ALL the possible combined values. ( I don't think I can fit all of them on here you will probaly have to do some work for it)

Hopefully this helps!!!

☁️ Answer ☁️

17. The puppy will grow 16 inches

One foot equals 12 inches. Lena's puppy will grow to be at most 28 inches. 28-12=16 inches.

18. 24.5

the possible values of the combined weights of the kittens is not more than 24.5 ounces. Since there are 7 kittens, the combined weight of the kittens is 7w, therefore the above expression could be read as "The combined weight of the kittens is less than 24.5 ounces

Point A is at (3,5). After being translated 10 units down, what are the coordinates of Point A?

Answers

Answer: The required co-ordinates of the new point are (6, 5).

Step-by-step explanation: Given that the point (-3, 15) undergoes a translation of 9 units right and 10 units down.

We are to find the coordinates of the new point.

We know that

if the point (x, y) undergoes a translation of 9 units right and 10 units down, then its translation rule is given by

(x, y) ⇒ (x+9, y-10).

Therefore, the co-ordinates of he new point are given by

(-3, 15) ⇒ (-3+9, 15-10) = (6, 5).

Thus, the required coordinates of the new point are (6, 5).

A chemist made six independent measurements of the sublimation point of carbon dioxide (the temperature at which it changes to dry ice). She obtained a sample mean of 196.64 K with a standard deviation of 0.66 K.
1. Use the Student’s t distribution to find a 95% confidence interval for the sublimation point of carbon dioxide.
2. Use the Student's t distribution to find a 98% confidence interval for the sublimation point of carbon dioxide.
3. If the six measurements had been 196.35, 196.32, 196.4 198.02, 196.36, 196.39, would the confidence intervals above be valid? Explain.

Answers

Answer:

(195.733, 197.547)

Step-by-step explanation:

Given that:

Mean, m = 196.64 K

Standard deviation, s = 0.66 K

Sample size, n = 6

Confidence interval :

Mean ± margin of error

Margin of error =Tcritical * s/sqrt(n)

Tcritical at α = 98% ; df = 6 - 1 = 5

Tcritical = 3.3648

Margin of Error = 3.3648 * 0.66/sqrt(6) = 0.9066

Confidence interval = 196.64 ± 0.9066

Lower boundary = 196.64 - 0.9066 = 195.733

Upper boundary = 196.64 + 0.9066 = 197.547

(195.733, 197.547)

Given the measurement :

X = 196.35, 196.32, 196.4 198.02, 196.36, 196.39

Mean = ΣX / n = 1179.84 / 6 = 196.64

Yes, confidence interval will be valid as theean obtained is within the calculated interval
