10 ways to divide 96 equally
96 divided by 2 = 48
96 divided by 3 = 32
96 divided by 4 = 24
96 divided by 6 = 16
96 divided by 8 = 12
96 divided by 12 = 8
96 divided by 16 = 6
96 divided by 24 = 4
96 divided by 32 = 3
96 divided by 48 = 2
Rational algebraic expression
x²-16/x²+8x+16
(x - 4)/(x + 4)
Step-by-step explanation:
[tex]\begin{aligned}\tt\frac{x^2-16}{x^2+8x+16}&=\tt\frac{x^2-4^2}{\left(x+4\right)^2}\\&=\tt\frac{\left(x+4\right)\left(x-4\right)}{\left(x+4\right)^2}\\&=\tt\frac{x-4}{x+4}\end{aligned}[/tex]
Note :
a² - b² = (a + b)(a - b)(a + b)² = a² + 2ab + b²a) 16 / (-4)
b) (-56) / 8
c) (-28) / (-2)
The ratio of boys to girls in a group is 7:3 There are 60 more boys than girls. Work out how many girls are there?
Answer:
45 girls
Step-by-step explanation:
There is 4 more boys than girls in each ratio.
60 boys / 4 = 15 groups where there is more boys
3 (girls) x 15 groups = 45 girls in total
The claim is that weights (grams) of quarters made after 1964 have a mean equal to 5.670 g as required by mint specifications. The sample size is n = 39 and the test
statistic is t= -3.276. Use technology to find the P-value. Based on the result what is the final conclusion? Use a significance level of 0.01.
State the null and alternative hypotheses
Hop
H.
(Type integers or decimals. Do not round)
Testing the hypothesis, we have that:
The null hypothesis is [tex]H_0: \mu = 5.67[/tex]The alternative hypothesis is: [tex]H_1: \mu \neq 5.67[/tex]The p-value of the test is of 0.002252.The p-value is 0.002252 < 0.01, which means that the final conclusion is that the mean weight of quarts made after 1960 is different than 5.67g.At the null hypothesis, we test if the mean is of 5.670g, that is:
[tex]H_0: \mu = 5.67[/tex]
At the alternative hypothesis, we test if the mean is different of 5.670g, that is:
[tex]H_1: \mu \neq 5.67[/tex]
The test statistic is t = -3.276, with the number of degrees of freedom given by:
[tex]df = n - 1 = 39 - 1 = 38[/tex]
The p-value is found using a t-distribution calculator, using a two-tailed test(as the alternative hypothesis is that the mean is different from the value), with t = -3.276 and 38 df. This p-value is of 0.002252.
The p-value is 0.002252 < 0.01, which means that the final conclusion is that the mean weight of quarts made after 1960 is different than 5.67g.

Answer:
x = -5
Step-by-step explanation:

First calculate the Subsets for set, then calculate the number of proper subsets {10,19,5,0}
The subsets of {10, 19, 5, 0} are
{ } - the empty set, or 1 subset of size 0
{10}, {19}, {5}, {0} - 4 subsets of size 1
{10, 19}, {10, 5}, {10, 0}, {19, 5}, {19, 0}, {5, 0} - 6 subsets of size 2
{10, 19, 5}, {10, 19, 0}, {10, 5, 0}, {19, 5, 0} - 4 subsets of size 3
{10, 19, 5, 0} - 1 subset of size 4
A proper subset of a set is any subset of that set that is not equal to that set. The only subset that is not a proper subset is {10, 19, 5, 0}, since that's the set itself. So there are 15 proper subsets.
In general, a set of size n has a total of 2ⁿ subsets, and 2ⁿ - 1 proper subsets.
At LaGuardia Airport for a certain nightly flight, the probability that it will rain is 0.07 and the probability that the flight will be delayed is 0.12. The probability that it will not rain the flight will leave on time is 0.87. What is the probability that it is raining if the flight has been delayed? Round your answer .
Probability of not raining and the flight leaving on time is equals to 0.320 .
De Morgan's law
P( A'∩ B') = P (A∪B)'
P (A∪B)' = 1 - P (A∪B)
P(A∪B) = P(A) + P(B) - P(A∩B)
According to the question,
Let Probability of rain = P(A)
= 0.07
Probability of flight delay =P(B) = 0.12
Therefore ,
Probability of rain and flight delay = P (A∩B)
= 0.87
Probability of not raining and flight on time = P( A'∩ B')
Substitute the values in the formula
P( A'∩ B') = 1 - [ 0.07 + 0.12 -0.87]
= 1- 0.68
= 0.32
= 0.320 ( nearest thousandth)

Answer:
m < U = 65°
Step-by-step explanation:
Given that m < PTU° = 115°, and that it is a supplement to < UTV, then we can establish that m < UTV = 65° because their angles must add up to 180°.
From this point forward, we'll name < UTV as < T of △VUT.
Now that we have the measure of < T, we can find out the value of the missing angle, < VUT, through the following equation:
180° = m < V° + m < T° + m < U°
180° = m < 50° + m < 65° + x
180° = m < 115° + x
Subtract m < 115 from both sides to isolate x:
180° - m < 115° = m < 115° - m < 115° + x
65° = x
To verify that we have the correct answer, we'll add up all the measures of the three angles of the triangle to see if it sums up to 180°:
180° = m < V° + m < T° + m < U°
180° = m < 50° + m < 65° + m < 65°
180° = m < 50° + m < 65° + m < 65°
180° = 180° (True statement).
Therefore, the measure of the missing angle, < U = 65°
