Step-by-step explanation:
34) The perimeter of a triangle is equal to the sum of the lengths of its sides
Sides: (6.2p + 4.5q) + (3.4p - 0.7r) + (2.9r - 4.1q)
Combine like terms (same variables)
(6.2p + 3.4p) + (4.5q - 4.1q) + (2.9r - 0.7r)
9.6p + 0.4q + 2.2r
A
35)
Time possibilities
1 hour - $3 - $5 = $-2 No
2 hours - $6 - $5 = $1 Yes
3 hours - $9 - $5 = $4 Yes
4 hours - $12 - $5 = $7 Yes
5 hours - $15 - $5 = $10 Yes
6 hours - $18 - $5 = $13 Yes
7 hours - $21 - $5 = $16 Yes
8 hours - $24 - $5 = $19 No
9 hours - $27 - $5 = $22 No

Answer:
Using the normal probability distribution, with a capacity of 350, it is enough for all abused on 90.82% of nights.
274 shelters will be needed.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation
, the zscore of a measure X is given by:
The Z-score 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. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
If the city’s shelters have a capacity of 350, will that be enough places for abused women on 95% of all nights?
What is the percentile of 350?
This is the pvalue of Z when X = 350.
has a pvalue of 0.9082.
Using the normal probability distribution, with a capacity of 350, it is enough for all abused on 90.82% of nights.
If not, what number of shelter openings will be needed?
The 95th percentile, which is X when Z = 1.645. So
274 shelters will be needed.
A piece of wire is cut into two pieces. That means each part would be assigned an unknown variable. Let one part be x and the other part be y.
That means,
If the longer part is x, and the longer part is 3cm longer than the shorter part, then we would have the following;
We can now refine the equation as follow;
ANSWER:
The length of the shorter piece of wire is 6cm
