Answer:
25, I believe
Step-by-step explanation:
Given a=7 and b=24,
c = 25
Answer:
25
Step-by-step explanation:
a² + b² = c², by Pythagoras
In this case 'x' is the 'c' for hypotenuse length
7² + 24² = x²
49 + 576 = x²
625 = x²
√625 = x
25 = x

At the beginning of the Occupation, the Nazis basically let the Jews go about their business. This all changes in October 1940. Measures are introduced one after the other. Civil servants must sign an official declaration stating whether they are Jewish or not. Just like in Germany earlier on, Jewish civil servants and teachers are fired from their jobs. At the beginning of 1941, all Jews in the Netherlands must register.

Bryan and Serena had the same amount of money initially. After Bryan donated $258 and Serena donated $234 to charity, Serena had 4 times as much as Bryan. How much had Serena in the end?
Answers
24 divided by 4 is 6
Answer:
Serena had $32 at the end.
Step-by-step explanation:
They both had x in the beginning.
Bryan donated $258, so now he has
x - 258
Serena donated $234, so now she has
x - 234
Serena now has 4 times as much money as Bryan.
x - 234 = 4(x - 258)
x - 234 = 4x - 1032
-3x = -798
x = 266
They both had $266.
$266 - $234 = $32
Answer: Serena had $32 at the end.

parallel lines p and q are cut by two non parallel lines m and n as shown in the figure the value of x is ? degrees and the value of y is ? degrees
Answers
Answer:
Step-by-step explanation:
x+102+115+(180-115)=360
x+282=360
x=78 degrees
y=115 degrees
Answer:
x = 78
y= 115
Step-by-step explanation:
On the angle where p and m meet, we have congruent angles that both equal 102 degrees. The adjacent angles will add up to 180 degrees on a line. So, to find the missing angle, do this:
180-102 = 78 degrees
x is equal to the top right angle where p meets m as they are congruent.
x = 78
You can find y by realizing that the given angle on q meets n are congruent angles. If this angle equals 115 degrees, then y must also equal 115 degrees.

The statement fourth "The population is all text messages she sent and the sample is the 50 text messages she randomly selected" is correct.
What is simple random sampling?Simple random sampling is a sampling strategy in which every item in the population has an equal probability of being chosen for the sample.
We have:
A student would like to know what proportion of the text messages she sends is to her best friend.
The number of sample methods she selects = 50 text messages
As the sample consists of the 50 texts she randomly chose from the population of all the texts she sent.
Thus, the statement fourth "The population is all text messages she sent and the sample is the 50 text messages she randomly selected" is correct.

Im not entirely sure
Step-by-step explanation:
When a certain basketball player takes his first shot in a game he succeeds with prob. 1/3. If he misses his first shot, he loses confidence and his second shot will go with prob. 1/4. If he misses his first 2 shots, his third shot will go with pro. 1/5. If he misses his first 3 shots, his fourth shot will go with prob. 1/6. If he misses his first 4 shots, the coach will remove hom from the game. Assume that the player keeps shooting until he succeeds or he is removed from the game. Let X denote the number of shots he misses until his first success or until he is removed from the game.
Required:
a. Compute the p.m.f. of X.
b. Compute E[X]
Answers
Solution :
Let the number of the shots that the player while playing misses until the first success = x
The random variable X can take the values {0, 1, 2, 3, 4}
[tex]$P(x=0)$[/tex] = probability of the player that does not misses the 1st shot
The probability of the player that he success at the 1st shot = [tex]$\frac{1}{3}$[/tex]
[tex]$P(x=1)$[/tex] = probability of the player that misses the 1st shot but succeeds in his 2nd shot [tex]$=\frac{2}{3} \times \frac{1}{4}$[/tex]
[tex]$=\frac{1}{6}$[/tex]
[tex]$P(x=2)$[/tex] = probability of the player that misses the 1st two shot but succeeds in the 3rd shot [tex]$=\frac{2}{3} \times \frac{3}{4}\times \frac{1}{5}$[/tex]
[tex]$=\frac{1}{10}$[/tex]
[tex]$P(x=3)$[/tex] = probability of the player that misses the 1st three shot but succeeds in the 4th shot [tex]$=\frac{2}{3} \times \frac{3}{4}\times \frac{4}{5} \times \frac{1}{6}$[/tex]
[tex]$=\frac{1}{15}$[/tex]
Similarly,
[tex]$P(x)$[/tex] = (probability of missing the 1st four shots) x (probability of removing te player after the 1st four shots missed)
[tex]$=\frac{2}{3} \times \frac{3}{4}\times \frac{4}{5} \times \frac{5}{6} \times 1$[/tex]
[tex]$=\frac{1}{3}$[/tex]
a). The p.m.f of the X
X = x 0 1 2 3 4
P(X=x) [tex]$\frac{1}{3}$[/tex] [tex]$\frac{1}{6}$[/tex] [tex]$\frac{1}{10}$[/tex] [tex]$\frac{1}{15}$[/tex] [tex]$\frac{1}{3}$[/tex]
b). [tex]$E(X) = \sum x \times P(X=x)$[/tex]
[tex]$= 0\times \frac{1}{3}+1\times \frac{1}{16}+2\times \frac{1}{10}+3\times \frac{1}{15}+4\times \frac{1}{3}$[/tex]
[tex]$=\frac{114}{60}$[/tex]

The atomic mass of a chemical element is the number of protons + number of neutrons in each atom of that element—electrons are ignored. Examples The atomic mass of hydrogen (H) is 1 (1 proton) and that of helium (He) is 4 (2 protons + 2 neutrons).
The gram atomic mass of a chemical element is the atomic mass of that element in grams. Example The gram atomic mass of H is 1 gram and that for He is 4 grams.
Astounding Fact There are approximately 6 x 1023 atoms in the gram atomic mass of every known chemical element. Examples There are 6 x 1023 atoms in 1 gram of H and in 4 grams of He. Hence, there are 12 x 1023 atoms, or 1.2 x 1024 atoms, in 2 grams of H and in 8 grams of He.
Standard carbon is Carbon 12, abbreviated C-12. Its atomic number is 12 (6 protons and 6 neutrons) and its gram atomic mass is therefore 12 grams.

(a) 1.2 x 1024 atoms (b) 12 x 1023 atoms (c) 4.8 x 1023 atoms

1. Elena donates some money to charity whenever she earns money as a babysitter. The table shows how much money, d, she donates for different amounts of money, m, that she earns.
a. What percent of her income does Elena donate to charity?
b.Which quantity, m or d, would be the better choice for the dependent variable in an equation describing the relationship between m and d.
PLEASE HELP!!! THANK YOU!!❤️
Answers
(a). Elena donates 12% of her income.
(b). d (amount donated) will be a better choice for the dependent variable, as it is always dependent on the income of Elena.
What is a dependent variable?You can control or set the independent variable. It affects the dependent variable, which changes as a result. The input is unrelated to the result, which is the dependent variable.
As per the given data:
money donated from money earned is given in the table.
For percent of her income donated to charity:
Total money donated / Total money earned
= (4.44 + 1.80 + 3.12 + 3.60 + 2.16) / (37 + 15 + 26 + 30 + 18)
= (15.12)/(126)
= 0.12
∴ Elena donates 12% of her income.
Hence, Elena donates 12% of her income and d (amount donated) will be a better choice for the dependent variable as it is always dependent on the income of Elena.
