Answer:
523.5miles
Step-by-step explanation:
Marcus traveled 65mph for 3.5hrs and 74mph for 4hrs. To find his total traveled distance we need to multiply the mph by the number of hours.
65x3.5=227.5mi
74x4=296mi
Add the number of miles together.
227.5+296=523.5miles

What is the value of x in the equation 4(2x – 8) = 8(4x + 2)?
Answer:
x=-2
Step-by-step explanation:
4(2x – 8) = 8(4x + 2)
Distribute
8x -32 = 32x+16
Subtract 8x from each side
8x-32 -8x = 32x+16-8x
-32 = 24x+16
Subtract 16 from each side
-32-16 = 24x+16-16
-48 = 24x
Divide by 24
-48/24 = 24x/24
-2 =x
A t-shirt increased in price by 1/4. After the increase it was £20. What was the original price of the t-shirt?
Answer:
£16
the t-shirt increased by 0.25. let's convert that to percentage
therefore it increased by 25%
By using cross multiplication we can write as follows:
125%=£20
100%=£ x
(100×20)/125= £16

A house on the market was valued at $478,000. After several years, the value increased by 8%. By how much did the house's value increase in dollars? What is
the current value of the house?
Answer:
$38240 increase$516240 current valueStep-by-step explanation:
Initial value of house is $478000
Change in value is 8% greater:
478000 + 8% = 478000 + 8*478000/100 = 478000 + 38240 =516240We need 8% of Value
[tex]\\ \sf\longmapsto 8\%\:of\;478000[/tex]
[tex]\\ \sf\longmapsto 0.08(478000)[/tex]
[tex]\\ \sf\longmapsto 38240\$[/tex]
Current value:-
[tex]\\ \sf\longmapsto 478000+38240=516240[/tex]
51 samples were analyzed, and the sample mean was 9.7 ounces. Can you determine the standard deviation of the sample
Using the Central Limit Theorem, it is found that the standard deviation for the sampling distribution of sample means is given by:
[tex]s = \frac{\sigma}{\sqrt{51}}[/tex].
In which [tex]\sigma[/tex] is the population standard deviation.The Central Limit Theorem states that, the sampling distribution of sample means of size n, from a population with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], has mean [tex]\mu[/tex] and standard deviation, which is also called standard error, [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
In this question, 51 samples, hence, [tex]n = 51[/tex]
Hence, applying the Central Limit Theorem, the standard deviation for the sampling distribution of sample means is given by:
[tex]s = \frac{\sigma}{\sqrt{51}}[/tex].
In which [tex]\sigma[/tex] is the population standard deviation.A similar problem, which also involves the Central Limit Theorem, is given at https://brainly.com/question/24663213

How do you solve for TSU? i’ll make you brainleist
Step-by-step explanation:
as we know, 1 exterior angle is equal to 2 interior angle
therefore let angle u be x.
now,
→ 65° + x = 105
→ x = 105 - 65 = 40°
therefore
TUS = 40°
and to know measure of angle TSU apply angle sum property of triangle in ∆TUS
so,
65 + 40 + TSU = 180
105 + TSU = 180
TSU = 180 - 105 = 75°
therefore,
TSU = 75°

27. A prime factor of 2310 is chosen at random. What is the
probability that the chosen factor will be greater than 7?
Step-by-step explanation:
The prime factorization of 2,310 is 2 × 3 × 5 × 7 × 11. Since it has a total of 5 prime factors, 2,310 is a composite number.
The probability of chosen factor will be greater than 7 will be ( 1 / 5 ).
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of sample
Given that a prime factor of 2310 is chosen at random. The probability will be calculated as:-
The prime factorization of 2,310 is 2 × 3 × 5 × 7 × 11.
Favourable outcome = 11 = 1
Total outcomes = ( 2,3,5,7,11) = 5
Probability = ( 1 / 5 )
Therefore, the probability of chosen factor will be greater than 7 will be ( 1 / 5 ).
