Answer:
(-1, -1) is not a solution to the system
Step-by-step explanation:
Y = 3x - 4. Substitute the points for x and y
2 = 3(2) - 4
2 = 2 solution
y = 3x - 4
-4 = 3(0) - 4
-4 = -4 solution
y = 3x - 4
8 = 3(4) - 4
8 = 8 solution
y = 3x - 4
-1 = 3(-1) - 4
-1 = -7 not solution

4. Which of the following indicates the multiplication property of equality when solving Vz= 5?
O A.Y2 = 2(5)
O B.2V) = 5
O C.212) = 2(5)
O D.V2 = 5/2
Answer:
D. 21.
Step-by-step explanation:
The general form of the equation of a circle is:
(x - a)^2 + (y - b)^2 = r^2 where r is the radius.
Comparing:
(x + 5)^2 + (y + 7)^2 = 21^2
So r^2 = 21^2
making r = √21^2
= 21.

According to genetic theory, the blossom color in the second generation of a certain cross of sweet peas should be red or white in a 3:1 ratio. That is, each plant has probability 3/4 of having red blossoms, and the blossom colors of separate plants are independent. Using the Binomial distribution, what is the exact probability that more than 7 out of 10 these plants have red blossoms
Answer:
The answer is "0.250".
Step-by-step explanation:
Given:
[tex]P(X=7) \\\\ n=10\\\\ p=0.75\\\\x \sim Binomial (n = 10, p = 0.75)\\[/tex]
[tex]P(X=7) =\binom{n}{x} P^{x} (1-p)^{(n-x)} \\\\[/tex]
[tex]= \binom{10}{7}(0.75)^7(1-0.75)^{10-7} \\\\=120 \times (0.75)^7 \times (0.25)^3\\\\=0.250[/tex]

[tex]Ladder = 18ft[/tex]
[tex]\theta = 76[/tex]
Required
The height which the ladder reaches on the wall
The question is illustrated with the attached image (solve for x).
Using sine formula, we have:
[tex]\sin(76) = \frac{x}{18}[/tex] --- i.e. sin = opposite/hypotenuse
Make x the subject
[tex]x = 18 * \sin(76)[/tex]
[tex]x = 18 * 0.9703[/tex]
[tex]x = 17.4654[/tex]

4. The pet store usually sells 12 puppies every 9 days. At this rate, how long will it take
them to sell 174 puppies?
Answer:
Approximately 131 days
Step-by-step explanation:
Let the store will take x days to sell 174 puppies.
Since, there is a relation of direct proportion between the puppies sold and number of days.
So,
[tex] \frac{12}{9} = \frac{174}{x} \\ \\ x = \frac{174 \times 9}{12} \\ \\ x = \frac{1,566}{12} \\ \\ x = 130.5 \: \\ \\ x \approx \: 131 \: days[/tex]

The area of a square is 1800 in2, how long is each diagonal?
9514 1404 393
Answer:
60 in
Step-by-step explanation:
The area of a square can be computed as ...
A = (1/2)d^2 . . . . where d is the length of the diagonal
For an area of 1800 in^2, the diagonal length can be found as ...
1800 in^2 = 1/2d^2
3600 in^2 = d^2
d = √3600 in = 60 in
The length of each diagonal is 60 inches.

A CD has a predetermined time limit before a withdrawal can be made.
This is the best statement that describes a characteristic of a CD (certificate of deposit) account.
A CD is a type of savings account that requires the depositor to commit to leaving their funds in the account for a predetermined period of time, called the term or maturity.
During this time, the funds are locked in and the depositor cannot withdraw them without incurring a penalty.
This makes a CD less flexible than a regular savings account but typically offers higher interest rates.
CD accounts do not usually allow for more withdrawals than a money market account, and there are no withdrawal minimums that are less than the account balance.
Hence, A CD has a predetermined time limit before a withdrawal can be made is the statement best describes a characteristic of a CD.
