Kylie drove 406 miles in 7 hours. If she continued at the same rate, how far would she travel in 19 hours?
Answer:
1,102
Step-by-step explanation
406/7=56 (unit rate)
56*19=1102
Answer:
The answer is 1,102
Step-by-step explanation:
First, we need to figure out how much per hour.
406 divided by 7 = 58
Now we multiply by the hours
58 x 19 = 1,102

Suppose 30% of the U.S. population has green eyes. If a random sample of size 1200 U.S. citizens is drawn, then the probability that less than 348 U.S. citizens have green eyes is _______.
Answer:
P(X is less than 348) = 0.2148
Step-by-step explanation:
Given that:
Sample proportion (p) = 0.3
Sample size = 1200
Let X be the random variable that obeys a binomial distribution. Then;
[tex]X \sim Bin(n = 1200,p =0.3)[/tex]
The Binomial can be approximated to normal with:
[tex]\mu = np = 1200 \times 0.3 \\ \\ \mu= 360[/tex]
[tex]\sigma = \sqrt{np(1-p) } \\ \\ \sigma = \sqrt{1200 \times (0.3)(1-0.3) } \\ \\ \sigma = 15.875[/tex]
To find:
P(X< 348)
So far we are approximating a discrete Binomial distribution using the continuous normal distribution. 348 lies between 347.5 and 348.5
Normal distribution:
x = 347.5, [tex]\mu[/tex] = 360, [tex]\sigma[/tex] = 15.875
Using the z test statistics;
[tex]z = \dfrac{x - \mu}{\sigma}[/tex]
[tex]z = \dfrac{347.5 - 360}{15.875}[/tex]
[tex]z = \dfrac{-12.50}{15.875}[/tex]
z = -0.7874
z ≅ - 0.79
The p-value for P(X<347.5) = P(Z < -0.79)
From the z tables;
P(X<347.5) = 0.2148
Thus;
P(X is less than 348) = 0.2148

Answer:
we get [tex]x^2=12-6\sqrt{3}[/tex]
Step-by-step explanation:
We are given: [tex]x=3-\sqrt{3}[/tex]
We need to find [tex]x^2[/tex]
Note: Since question is not clear, I am assuming that we need to find [tex]x^2[/tex]
Solving:
[tex]x=3-\sqrt{3} \\Taking \ square \ on \ both \ sides\\x^2=(3-\sqrt{3})^2\\[/tex]
We know that [tex](a-b)^2= a^2-2ab+b^2[/tex]
Using formula and simplifying
[tex]x^2=(3)^2-2(3)(\sqrt{3})+(\sqrt{3})^2\\x^2=9-6\sqrt{3} +3\\x^2=12-6\sqrt{3} \\[/tex]
So, we get [tex]x^2=12-6\sqrt{3}[/tex]
Dave bakes 12 cakes in 3 minutes. If b represents the numbers cakes David bakes in minutes . What is a linear equation that represents this situation
Answer:
The linear equation will be:
b = 4a
Here,
b = numbers of cakes David bakes
a = the time taken by David to bake cakes
Step-by-step explanation:
Let 'b' represents the numbers of cakes David bakes in minutes.
Let 'a' represents the time David takes to make 12 cakes
As Dave bakes 12 cakes in 3 minutes.
unit rate = 12/3 = 4 cakes / per minute
The unit rate can also be treated as a slope as it is just representing the rate of change.Thus, the linear equation will be:
b = 4a
Here,
b = numbers of cakes David bakes
a = the time taken by David to bake cakes
VERIFICATION
if a = 3 minuts
then
b = 4(3) = 12 cakes
and
if a = 2 minutes
then
b = 4(2) = 8 cakes
and
if a = 1 minute
then
b = 4(1) = 4 cakes
Thus, the required equation is:
b = 4a
Here,
b = numbers of cakes David bakes
a = the time taken by David to bake cakes

Answer:
20 feet
Step-by-step explanation:
Parimeter is how far you would walk if you made a lap around the shape, walking on the edge lines like a balance beam.
To find perimeter, we need to add up all the sides.
Because it's a square each side has the same length.
There are 4 sides.
5 x 4 = 20
or 5 + 5 + 5 + 5 = 20
The perimeter is 20 feet
you want to obtain a sample to estimate a population proportion. at this point in time, you have no reasonable preliminary estimation for the population proportion. you would like to be 95% confident that you estimate is within 2% of the true population proportion. how large of a sample size is required
Answer:
The value is [tex]n =2401 [/tex]
Step-by-step explanation:
From the question we are told that
The margin of error is E = 2%= 0.02
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Here we are going to assume that the sample proportion is [tex]\^ p = 0.50[/tex]
Generally the sample size is mathematically represented as
[tex]n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p ) [/tex]
=> [tex]n =[\frac{ 1.96 }{ 0.02} ]^2 * 0.5 (1 -0.5 ) [/tex]
=> [tex]n =2401 [/tex]

Specify the null and alternative hypotheses for testing whether the true average number of minutes in the past month that adults walked for the purpose of health or recreation is than minutes.
Complete question is;
In a study investigating a link between walking and improved health, researchers reported that adults walked an average of 873 minutes in the past month for the purpose of health or recreation.
Specify the null and alternative hypotheses for testing whether the true average number of minutes in the past month that adults walked for the purpose of health or recreation is lower than 873 minutes
Answer:
Null Hypothesis: H0: μ = 873
Alternative hypothesis: Ha: μ < 873
Step-by-step explanation:
From the study, the claim is that the true average number of minutes gotten from the population average in the past month that the adults had walked for the purpose of health or recreation is lower than the average of 873 minutes.
Now, the population study says it's equal to 873 minutes.
Thus, the hypotheses can be written as;
Null Hypothesis: H0: μ = 873
Alternative hypothesis: Ha: μ < 873
A store has 300 televisions on order, and 40% are high definition. How many televisions on order are high definition? You may find the bar model useful in completing this problem.
Answer:
120
Step-by-step explanation:
There are 120 high definition televisions are in Order.
What is Percentage?Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.
Here,
Total television = 300
Percentage of High definition television = 40%

Find an equation for the perpendicular bisector of the line segment whose endpoints
are (-1, 4) and (-9, --6).
Answer:
y = -0.8x - 5
Step-by-step explanation:
x1 = (XA + XB) / 2 = -5
y1 = (YA + YB) / 2 = -1
m = (XA - XB) / (YA - YB) = -0
__________________________________________
(y - -1) = -0.8(x - -5)
y - -1 = -0.8x - 4
y = -0.8x - 4 + -1
y = -0.8x - 5

12
What is the length of segment KH?
Answer:
5
Step-by-step explanation:
∆FGH is similar to ∆JKH. Therefore, their corresponding lengths are proportional to one another. Thus:
[tex] \frac{GH}{KH} = \frac{FH}{JH} [/tex]
GH = x + 15
KH = x
FH = 12 + 4 = 16
JH = 4
Plug in the values
[tex] \frac{x + 15}{x} = \frac{16}{4} [/tex]
Cross multiply
[tex] (x + 15) \times 4 = 16 \times x [/tex]
[tex] 4x + 60 = 16x [/tex]
Subtract 4x from each side
[tex] 60 = 16x - 4x [/tex]
[tex] 60 = 12x [/tex]
Divide both sides by 12
x = 5
KH = x = 5

what is 1 and 5/32 as a decimal
Answer:
1 5/32 is equal to 1.15625 in decimal form.
Step-by-step explanation:
Hope this helped, Have a Great Day!!
1 and 5/32 is equivalent to 1.15625 as a decimal.
To convert the mixed number 1 and 5/32 to a decimal, you need to combine the whole number and the fractional part.
First, you convert the fractional part to a decimal.
The denominator of 32 tells you that there are 32 equal parts in a whole.
To determine the value of 5/32, you divide the numerator (5) by the denominator (32):
5 ÷ 32 = 0.15625
Next, you add the decimal value of the fractional part (0.15625) to the whole number (1):
1 + 0.15625 = 1.15625
Therefore, 1 and 5/32 is equivalent to 1.15625 as a decimal.
