Keiko uses 6.9 pints of blue paint and white paint to paint her bedroom walls. 2/5 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Answer: [tex]4.14\ \text{pints}[/tex]
Step-by-step explanation:
Given
Keiko uses 6.9 Pints of blue and white paint
If the fraction of blue paint is [tex]\frac{2}{5}[/tex], then thr fraction of white paint is
[tex]1-\dfrac{2}{5}=\dfrac{3}{5}[/tex]
Amount of white paint is
[tex]\Rightarrow \dfrac{3}{5}\times 6.9=4.14\ \text{pints}[/tex]
so if squared by 2 means times the number by itself. would 2 squared of 60 be 120?

What two numbers multiply to get 18 but add to get -12
Answer:
-6+3[tex]\sqrt{2}[/tex] and -6-3[tex]\sqrt{2}[/tex]
Step-by-step explanation:
xy = 18
x+y = -12
y = -12-x
substitution method:
x(-12-x) = 18
-12x - x² - 18 = 0
-x² - 12x - 18 = 0
-(x² + 12x + 18) = 0
used quadratic formula:
(-12±√144 - 4(18)) ÷ 2
(-12 ± [tex]\sqrt{72}[/tex]) ÷ 2
(-12 ± 6[tex]\sqrt{2}[/tex]) ÷ 2
= -6 ± 3[tex]\sqrt{2}[/tex]
Multiply and simplify.

URGENT 30 POINTS An engineer needs to find the length of a beam to support the beam holding the wall. If the two beams are perpendicular to one another, and a=4 m and b=1 m, find z. Give your answer to one decimal place.
The value of z in the given arrangement is 2 m.
What are similar triangles?Similar triangles are the triangles that look similar to each other, but their sizes might not be exactly the same.
Also,
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.
Given that, an engineer needs to find the length of a beam to support the beam holding the wall, the two beams are perpendicular to one another, and a=4 m and b=1 m, we need to find z.
So, here we will use the concept of similar triangles,
According to the definition the corresponding sides are in proportion.
So, we get,
z/a = b/z
z² = 4
z = 2
Hence, the value of z in the given arrangement is 2 m.

what is the length of AC
Answer:
16
Step-by-step explanation:
what do I do and how
Answer:
f(x) is another way of saying "y", but when x is replaced with a number, it just means that x = that number.
Since A says to find f(7), it means that in this scenario, x = 7. So, 2x - 5 is turned into 2(7) - 5, which equals 14 - 5, which equals 9.
So, f(7) = 9.
You can then apply this to the rest of the numbers you are given.

y=13 is a solution to the inequality y+4<16
Answer:
No
Step-by-step explanation:
First subtract 16 from both sides
y + 4 < 16y + 4 - 16 < 16 - 16y - 12 < 0 So 0 has to be greater than whatever is on the leftIf y = 13 is put into the inequality you get 13 - 12 < 0.What is ultimately true is that 1 < 0 Is 1 smaller than 0?No13 is not a solution to the original inequality.

In a congressional district, 55% of the registered voters are Democrats. Which of the following is closest to the probability of getting less than 50% Democrats in a random sample of size 100?
Is this an example of a sample proportion OR a sample mean?
Answer:
sample mean
Step-by-step explanation:
Using the normal distribution and the central limit theorem, considering that this is a sample proportion, as we are dealing with percentages, it is found that there is a 0.1562 = 15.62% probability of getting less than 50% Democrats in a random sample of size 100.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X. By the Central Limit Theorem, the sampling distribution of sample proportions of a proportion p in a sample of size n has mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1 - p)}{n}}[/tex].In this problem:
55% of the registered voters are Democrats, hence [tex]p = 0.55[/tex].A sample of size 100 is taken, hence [tex]n = 100[/tex]The mean and the standard deviation of the sampling distribution of sample proportions are given by:
[tex]\mu = p = 0.55[/tex]
[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.55(0.45)}{100}} = 0.04975[/tex]
The probability of getting less than 50% Democrats in a random sample of size 100 is the p-value of Z when X = 0.5, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{0.5 - 0.55}{0.04975}[/tex]
[tex]Z = -1.01[/tex]
[tex]Z = -1.01[/tex] has a p-value of 0.1562.
0.1562 = 15.62% probability of getting less than 50% Democrats in a random sample of size 100.

Derrick started a new job at McDonald's. He makes $10 per hour. Which
equation models his total weekly earnings y, in terms of the number of
hours he works x? *
Answer:
10x=y.
Step-by-step explanation:
10 represents the amount he earns an hour. X represents the number of hours so 10x. 10 times the amount of hours equals y (total amount of money)
Answer:
y = 10x
Step-by-step explanation:
The total earnings, y, is equal to the hourly rate, 10, times x, the hours worked.
y equals 10 times x, or, in equation form, y = 10x.
