Answer: The lorry is traveling 10 mph over the expected speed.
Step-by-step explanation:
If 200 miles takes 4 hours, the speed is 200mi/4hr which is 50 mph.
If the distance is increased by 20%, the distance is 240 miles.
240mi/4hr = 60mph
The difference is 10mph

A recent Gallop poll showed that 672 of 1019 adults nationwide think that marijuana should be legalized. a) Find the margin of error that corresponds to a 95% confidence interval.
Answer:
the margin of error is 0.029
Step-by-step explanation:
The computation of the margin of error is as follows;
Point estimate = sample proportion
[tex]= \hat p[/tex] = x ÷ n = 672 ÷ 1019 = 0.659
Now
= 1 - [tex]\hat p[/tex]
= 1 - 0.659
= 0.341
[tex]Z\alpha/2[/tex] = Z_0.025 = 1.96
Now
a) Margin of error = E is
[tex]= Z\alpha / 2 \times \frac{((\hat p \times (1 - \hat p ))}{(\sqrt / n)} \\\\= 1.96 (\sqrt \frac{ (0.659 \times 0.341)}{(1019)} \\\\= 0.029[/tex]
Hence, the margin of error is 0.029

Ali took five Math tests during the semester and the mean of his test score was 85. If his mean after the first three was 83, What was the mean of his 4th and 5th tests
Answer:
88
Step-by-step explanation:
Mean of five test = 85
Sum of five tests = 85*5 = 425
Mean of first three test =83
Sum of first three test = 83 * 3 = 249
Sum of 4th and 5th test scores = 425 - 249
= 176
Mean of his 4th and 5th test = 176/2 = 88

plz help mezzzzzaZzZzZzZzZzZ
Answer:
1/33Step-by-step explanation:
Typically you would want to solve this equation by dividing both sides by 3 but we need to find an equivalent equation that gives the same answer. 3 divided by 3 is the same as 3 times 1/3. Thus;
3x * 1/3 = 9 * 1/3
x = 3
Best of Luck!
Answer:
3
Step-by-step explanation:
3x = 9
= 3x/3 = 9/3
= 3
n/33 = 4/11
Please select the best answer from the choices provided
A: n = 90 3/4
B: n = 16
C: n = 1 1/3
D: n = 12
Answer: D. n = 12
================================
Work Shown:
n/33 = 4/11
11*n = 33*4 ... cross multiply
11n = 132
n = 132/11 ... divide both sides by 11
n = 12
Answer:
D: n = 12
Step-by-step explanation:
n/33=4/11
we multiply by 33
n=4*33/11
33 can be divided by 11
n=4*3
n=12

How do I know if the function is a linear function?
Answer:
This is not a linear function.
Step-by-step explanation:
It is a quadratic function. If you were to make a table of the x and y values of the function it would look like this:
x y
0 -4
1 -1
2 8
Just by looking at these three values, we can see that they do not increase at a consistent rate. It increases by 3 from 0 to 1, but increase by 9 from 1 to 2. You can tell if a function is linear by seeing if it increases at a constant rate. (In this case it does not)

Pentru sala de mese a scolii s-au adus 12 scaune si 7 mese, plătindu-se 320lei.Știind că 4 scaune costă cât trei mese, află prețul unui scaun și prețul unei mese.
Răspuns:
Costul scaunului = 15
Costul mesei = 20
Explicație pas cu pas:
Dat fiind:
Să prețul scaunelor = c; pretul mesei = t
12c + 7t = 320 - - - (1)
4c = 3t; c = 3/4 t - - - (2)
Introducerea c = 3 / 4t în (1)
12 (3 / 4t) + 7t = 320
9t + 7t = 320
16t = 320
t = 320/16
t = 20
c = 3 / 4t
c = 3/4 (20)
c = 15
Costul scaunului = 15
Costul mesei = 20
