Answer:
[tex]Part = \frac{19}{20}[/tex]
[tex]Lessons = 23[/tex]
Step-by-step explanation:
Given:
[tex]Dancing\ Lessons = 24[/tex]
[tex]April = \frac{3}{4}[/tex]
[tex]May = \frac{1}{5}[/tex]
Required:
Determine the part she took
To solve this, we simply add up the part she took in April and May.
[tex]Part = \frac{3}{4} + \frac{1}{5}[/tex]
Take LCM
[tex]Part = \frac{15 + 4}{20}[/tex]
[tex]Part = \frac{19}{20}[/tex]
Hence, she took [tex]\frac{19}{20}[/tex] of the dancing lesson.
However, to calculate the number of lesson.
We have to multiply [tex]\frac{19}{20}[/tex] by the total dancing lessons.
[tex]Lessons = \frac{19}{20} * 24[/tex]
[tex]Lessons = \frac{19* 24}{20}[/tex]
[tex]Lessons = \frac{456}{20}[/tex]
[tex]Lessons = 22.8[/tex]
[tex]Lessons = 23[/tex] ---- Approximated

Cathy bough treats at her local bakery the past two weeks. The first week she bought 6 donuts and 3 muffins and paid $42. The second week she bought 3 donuts and 2 muffins and paid $24. How much does it cost for each donut and each muffin?
Answer:
Donuts are $4 and Muffins are $6
Step-by-step explanation:
Start by setting up both equations:
6d+3m=42
3d+2m=24
Then multiply the second equation by -2:
-6d-4m=-48
Then subtract the second equation by the first:
6d+3m=42
-6d-4m=-48
The sixes will cancel out and you'll have the equation:
-m=-6 or m=6
This tells you that each muffin is $6
Then you want to plug in six for m in one of the original equations:
3d+2(6)=24
Then solve for d:
3d+12=24
3d=12
d=4
This tells you that each dount is $4

An insurance company checks police records on 582 accidents selected at random and notes that teenagers were at the wheel in 91 of them. Which is a correct 90% confidence interval for the proportion of all auto accidents that involve teenage drivers
Answer:
The 90% confidence interval is [tex]0.1316 < p < 0.1812[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 582
The number of teenagers at the wheel is k = 91
Generally the sample proportion is mathematically represented as
[tex]\^ p = \frac{k}{n}[/tex]
=> [tex]\^ p = \frac{91}{582}[/tex]
=> [tex]\^ p = 0.1564[/tex]
From the question we are told the confidence level is 90% , hence the level of significance is
[tex]\alpha = (100 - 90 ) \%[/tex]
=> [tex]\alpha = 0.10[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.645[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } [/tex]
=> [tex]E = 1.645 * \sqrt{\frac{0.1564 (1- 0.1564)}{582} } [/tex]
=> [tex]E = 0.0248 [/tex]
Generally 95% confidence interval is mathematically represented as
[tex]\^ p -E < p < \^ p +E[/tex]
=> [tex]0.1564 -0.0248 < p < 0.1564 + 0.0248[/tex]
=> [tex]0.1316 < p < 0.1812[/tex]

Answer:
C. 57
Step-by-step explanation:
all triangles add up to 180. the tick marks show that ∠D and ∠ E are congruent so you do this and solve for x:
(4x + 1) + (4x + 1) + (5x - 4) = 180
13x - 2 = 180
13x = 182
x = 182/13
x = 14
4(14) + 1 = 57

A triangle has two sides of length 5 and 11. What is the smallest possible whole-number
length for the third side?
The smallest possible whole number length for the third side is 7
Data obtained from the question1st length = 52nd length = 113rd length =?How to determine the smallest possible length of the 3rd sideCase 1
1st + 2nd > 3rd
5 + 11 > 3rd
16 > 3rd
3rd length < 16
Case 2
1st + 3rd > 2nd
5 + 3rd > 11
3rd > 11 - 5
3rd > 6
Thus, we have
6 < 3rd length < 16
Since the 3rd length is greater than 6, then the smallest possible length for the 3rd side is 7

What is a way to write this sentence as an algebraic inequality?
Answer:
It's C.
Step-by-step explanation:
Did the test
The inequality is y/9 - x > 21.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
x less than the quantity y divided by 9 is more than 21.
Now, writing the mathematical Inequality for the given statement is
x less than the quantity y divided by 9
y/9 -x
and, more than 21.
y/9 - x > 21
Hence, the inequality is y/9 - x > 21.
