Step-by-step explanation:
Find the area of the triangle
Answer:
The answer to this problem is 12.5.
Step-by-step explanation:
The formula for finding the area of a triangle is b * h * 1/2 or divide by 2 (base times height times one-half or two).
Since this is a equilateral triangle, all of the sides are equivalent to each other. Since we know one of the sides is 5, all of the sides are 5.
5 * 5 = 25
Then you need to multiply this answer by 1/2 or divide by 2, whichever is easier.
25 / 2 = 12.5
The answer is 12.5.
Also, it would be FANTABULOUSLY AMAZING if I could get brainliest!!!

Answer:
33
Step-by-step explanation:
angles on a straight line sum up to 180°
104+x+x+10=180
114+2x=180
2x=180-114
2x=66
x=33
Answer:
C. 33
Step-by-step explanation:
So we have 180 degree line here, so lets take 104 and add the 10 from the expression inside the parenthesis on the other angle. We add 43 to 114 and get 147. We can then add 147+33 and get 180 which is equivalent to the angle.

Kane's Furniture Store advertised a table at a 13% discount. The original selling price was $113, and the sale price was $100. Was the sale price consistent with the
ad? Explain
Select the correct choice below and, if necessary, fill in the answer box within your choice.
A. No, the sale price was higher than it should have been
(Round to the nearest cent) __
B. No, the sale price was 5 lower than it should have been
(Round to the nearest cent.)__
C. Yes, the sale price was consistent with the ad, because it represents a 13% discount.
Answer:
A
Step-by-step explanation:
100%=$113 what about 87( 100-13)(113×85)÷100ans is 98.31 which should be the sale price but the sale price is 100 it is $16.90 higherA philosophy professor assigns letter grades on a test according to the following scheme. A: Top 10% of scores B: Scores below the top 10% and above the bottom 58% C: Scores below the top 42% and above the bottom 20% D: Scores below the top 80% and above the bottom 9% F: Bottom 9% of scores Scores on the test are normally distributed with a mean of 67.3 and a standard deviation of 7.3. Find the numerical limits for a D grade. Round your answers to the nearest whole number, if necessary.
Answer:
The numerical limits for a D grade are 58(lower limit) and 61(upper limit).
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set 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]
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 p-value, we get the probability that the value of the measure is greater than X.
Scores on the test are normally distributed with a mean of 67.3 and a standard deviation of 7.3.
This means that [tex]\mu = 67.3, \sigma = 7.3[/tex]
D: Scores below the top 80% and above the bottom 9%
This means that lower bound is the 9th percentile and the upper bound is the 100 - 80 = 20th percentile.
9th percentile:
This is X when Z has a pvalue of 0.09. So X when Z = -1.34.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1.34 = \frac{X - 67.3}{7.3}[/tex]
[tex]X - 67.3 = -1.34*7.3[/tex]
[tex]X = 57.52[/tex]
Rounding to the nearest whole number, 58.
20th percentile:
This is X when Z has a pvalue of 0.2. So X when Z = -0.84
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-0.84 = \frac{X - 67.3}{7.3}[/tex]
[tex]X - 67.3 = -0.84*7.3[/tex]
[tex]X = 61.17[/tex]
Rounding to the nearest whole number, 61.
The numerical limits for a D grade are 58(lower limit) and 61(upper limit).

Bianca bought a pack of rechargeable batteries for
$9.99. If the sales tax on the batteries is 3% and Bianca
pays with $11 cash, how much change will she get back?
hi
price all taxes included is : 9.99 + 0.03*9.99 ≈ 10.29
So change is : 11 - 10.29 = 0.71
Answer:
acualy you would divide 9.99 by 3

The length and width of a rectangle are 19.2 cm and 12.4cm respectively. Find the angle between a diagonal and the shorter side of the rectangle.
9514 1404 393
Answer:
57.1°
Step-by-step explanation:
The sides of the rectangle are adjacent and opposite the angle, so the measure is ...
α = arctan(opposite/adjacent) = arctan(19.2/12.4) ≈ 57.1°
The angle between the diagonal and the short side is about 57.1°.

what is BD?
please help i can’t fail another test
Answer:
C. 8
Step-by-step explanation:
BD is the altitude of the right triangle.
Apply the altitude theorem of a triangle to find BD. Based on the theorem, thus:
h = √(xy)
Where,
h = BD
x = 16
y = 4
Plug in the values
BD = √(16*4)
BD = √64
BD = 8

Its a math question, see attachments
Answer:
1) A) 25%
2) B) 16%
3) A) 93%
Step-by-step explanation:
1)
0.25 = 25%
2)
More than 3 means, 4 and 5
0.12 + 0.04 = 0.16 = 16%
3)
x ≥ 1
So that means 1+ days (everything except 0)
0.25 + 0.18 + 0.34 + 0.12 + 0.04
0.93 = 93%

g The proportion of U.S. births that result in a birth defect is approximately 1/33 according to the Centers for Disease Control and Prevention (CDC). A local hospital randomly selects five births and lets the random variable X count the number not resulting in a defect. Assume the births are independent. What is the probability that at least one of the births results in a defect
Answer:
0.1426 = 14.26% probability that at least one of the births results in a defect.
Step-by-step explanation:
For each birth, there are only two possible outcomes. Either it results in a defect, or it does not. The probability that a birth results in a defect is independent of any other birth. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
The proportion of U.S. births that result in a birth defect is approximately 1/33 according to the Centers for Disease Control and Prevention (CDC).
This means that [tex]p = \frac{1}{33}[/tex]
A local hospital randomly selects five births.
This means that [tex]n = 5[/tex]
What is the probability that at least one of the births results in a defect?
This is:
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{5,0}.(\frac{1}{33})^{0}.(\frac{32}{33})^{5} = 0.8574[/tex]
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.8574 = 0.1426[/tex]
0.1426 = 14.26% probability that at least one of the births results in a defect.
