Answer: 107/100x
1.07x
Step-by-step explanation:
Since the price of the model is x dollars, and she also has to pay a 7% tax, the amount that Leila will pay in total for the model will be the addition of the price of the model and the tax. This will be:
= x + (7% × x)
= x + (7/100 × x)
= x + (0.07 × x)
= x + 0.07x
= 1.07x
This can also be 107/100x

Need Help With My Geometry Work Plz Help
Answer:
Step-by-step explanation:
(number of sides-2)*180 = (6-2)*180 = 720°
a= 720/6= 120°
lines form 180° angles
b= 180-120= 60°
sum of angles in a triangle is 180, and the angles are ≡
c=180/3 = 60°
c and d are supplementary angles (they add to 180)
d= 180-60 = 120°
d ≡ e+e because are vertical angles
e= 120/2 = 60°
sum of angles in a triangle is 180
f= 180 -90-60 = 30°
(number of sides-2)*180 = (5-2)*180 = 540°
g= 540/5= 108°

A researcher selects a sample and administers a treatment for anxiety to the individuals in the sample. If the sample is used for a hypothesis test, what does the null hypothesis (H0) put forth about the treatment? *
Answer:
H0 : the treatment has no effect
Step-by-step explanation:
The test is formulated as hypothesis . Here the test ist that whether the treatment has affected or not . So the null hypothesis can be formulated as
H0 : the treatment has no effect
against the claim
Ha: the treatment has an effect.
The null hypothesis is the test performed and the alternate hypothesis is the claim against the test. Therefore they are opposite of each other.
The cost of a shirt decreases by 18%. After the discount, the shirt costs $61.91. How much did the shirt cost before the
discount?
Answer:
$75.5
Step-by-step explanation:
The first step is to calculate the percentage decrease
= 100-18
= 82%
Therefore the original cost of the shirt before the discount can be calculated as follows
= 82/100 × x = 61.91
= 82x/100= 61.91
Cross multiply
82x= 100×61.91
82x= 6191
x = 6191/82
= 75.5
Hencd the original cost of the shirt is $75.5
Answer:
75.50
Step-by-step explanation:
Which situation can be represented by the equation y = 12 x ?
Answer:
Let's solve for x.
y=12x
Step 1: Flip the equation.
12x=y
Step 2: Divide both sides by 12.
12x /12 = y /12
x= 1 /12 y
Answer: x= 1 /12 y

The rate at which a chemical decomposes is increasing at a continuous 6.6 % % . What is the actual hourly percent increase
Answer:
the actual hourly percent increase is 6.823 %
Step-by-step explanation:
Given that data in the question;
rate chemical decomposes increasing continuously at 6.6 %,
r = 6.6% = 0.066
actual hourly percent increase = ?
Now,
hourly percent increase = ( [tex]e^r[/tex] - 1 ) × 100%
we substitute
hourly percent increase = ( [tex]e^{0.066[/tex] - 1 ) × 100%
hourly percent increase = ( 1.06823 - 1 ) × 100%
hourly percent increase = 0.06823 × 100%
hourly percent increase = 6.823 %
Therefore, the actual hourly percent increase is 6.823 %

You wondered if the sugar content in energy dinks is really the same as labeled in the products. The disclosure on Red Bull 12 oz. dink state it contains 34g sugar. You randomly sampled 40 cans and measured its sugar content and found a sample mean of 35.6 and a standard deviation of 0.5. The correct hypotheses for said study should be
Answer:
The null hypothesis should be [tex]H_0: \mu = 12[/tex]
The alternate hypothesis should be [tex]H_1: \mu \neq 12[/tex]
Step-by-step explanation:
You wondered if the sugar content in energy drinks is really the same as labeled in the products. The disclosure on Red Bull 12 oz.
At the null hypothesis, we test if the sugar content is the same labeled, that is:
[tex]H_0: \mu = 12[/tex]
At the alternate hypothesis, we test if the sugar context is different from the labeled, that is, different of 12.
[tex]H_1: \mu \neq 12[/tex]

Five candy bars and two cupcakes cost $12. Three candy bars and three cupcakes cost $11.25. Find the cost of each item
Answer:
$23.25
Step-by-step explanation:
12+11.25
Answer:
candy bars = a
cupcakes = b
a=1.5$
b=2.25$
Step-by-step explanation:
candy bars = a
cupcakes = b
1)5a+2b = 12
2)3a + 3b = 11.25
We can understand
3a + 3b = 3(a+b)= 11.25
a+b = 11.25÷3 = 3.75
from No.2 equation.
than we do
(5a+2b) - 2(a+b)
and we got 3a
so
12 - 7.5 = 4.5 = 3a
a=1.5$
b=2.25$

|x-4| if x>4
can you please help me
Answer: x - 4 without the absolute value bars surrounding it
=================================================
Explanation:
If x is larger than 4, then x-4 is positive. For example, if x = 5, then
x-4 = 5-4 = 1
So for cases when x > 4, the |x-4| and x-4 are the same identical expression. Try out more values of x to compare the two outputs. I recommend making a table with 3 columns. You'll have x in column 1, then |x-4| in column 2, and x-4 in column 3. You should find that the outputs for columns 2 and 3 are identical when x is larger than 4.
It's only when x < 4 is when |x-4| and x-4 differ. Instead we would say |x-4| = -(x-4). But we aren't focused on this case.
In short, when x > 4, we simply drop the absolute value bars to get the answer x - 4
Guys please help do I multiply or divid & which number will I be diving w or multiply
Answer:
1. a) $24, b) $36, c) $48
2. a) $18, b) $27, c) $36
3. a) $1.64, b) $2.46, c) $3.28
5. a) $30, b) $50, c) $70
6. a) $4.05, b) $6.75, c) $10.80
7. a) $14.85, b) $24.75, c) $39.60
Explanations:
Whatever we multiply the item by, we multiply the cost by. If we double the number of socks, we double the price. If we triple the number of socks, we triple the price.
1. a) 3 costs $12, and 3 x 2 = 6, so we do the same to the price: $12 x 2 = $24
b) 3 times 3 is 9, so 3 x 12 gives you that cost, $36
c) 3 x 4 = 12, so 12 x 4 = $48
2. a) 3 pairs is $9, and we need 6 pairs. 3 x 2 = 6, so we also multiply the price x 2 = $18
b) 3 x 3 = 9 pairs, multiply the cost times 3 as well. 9 x 3 = $27
c) 3 x 4 = 12, multiply the cost x 4. 9 x 4 = 36
3. 4 apples cost $0.82
a) 4 x 2 = 8 apples, $0.82 x 2 = $1.64
b) 4 x 3 = 12 apples, $0.82 x 3 = $2.46
c) 4 x 4 = 16 apples, $0.82 x 4 = $3.28

To estimate the mean length of rattlesnakes, 10 such snakes are randomly selected. Their lengths, in inches, are as follows: 40.2 43.1 45.4 44.5 39.5 40.2 41.0 41.6 43.1 44.9 Find a 90% confidence interval for the mean length of all rattlesnakes.
Answer:
The confidence interval will be "41.04, 43.81".
Step-by-step explanation:
Given that,
Sample size,
n = 10
Sample total,
423.5
Sample mean,
[tex]\bar X =\frac{423.5}{10}[/tex]
[tex]=42.35[/tex]
Sample variance,
[tex]s = \sqrt{4.5894}[/tex]
[tex]=2.1423[/tex]
[tex]df=n-1[/tex]
[tex]=9[/tex]
[tex]t^*=18331[/tex]
Now,
The margin of error will be:
⇒ [tex]E=\frac{s\times t^*}{\sqrt{n} }[/tex]
[tex]=\frac{2.1423\times 1.8331}{\sqrt{9} }[/tex]
[tex]=\frac{3.928}{3 }[/tex]
[tex]=1.309[/tex]
hence,
The 90% confidence level will be:
= [tex](\bar X-E),(\bar X+E)[/tex]
By substituting the values, we get
= [tex](42.35-1.309),(42.35+1.309)[/tex]
= [tex](41.04),(43.81)[/tex]
