Answer:
1. p value = 0.0203
2. We conclude that the market share for cars are different from what was suggested by the nation wde sales in 2017
Step-by-step explanation:
first we solve for the chisquare of this data.
from the attachment i have uploaded, a table of the ch square that i calculate gave:
Chisquare = 14.99
n = 7
degree of freedom = 7-1 = 6
we formulate hypothesis
H0; no diference in market share
H1: there is difference in market share
alpha = 0.05
we find the p value using the excel formula
CHIDIST(14.99, 6)
p value = 0.0203
the p value lies between 0.01 and 0.025
so we reject null and conclude that market share for for cars are different from what is suggested by nationwide sales in 2017

sorry, missed the actual question.
the second model fits the problem.
In a lab experiment, 100 bacteria are placed in a petri dish. The conditions are such
that the number of bacteria is able to double every 13 hours. How long would it be, to
the nearest tenth of an hour, until there are 156 bacteria present?
Answer: 8.34 hr
Step-by-step explanation:
Given
Initially, 100 bacteria are placed in a Petri dish
bacteria doubles in every 13 hours
So, a function that defines this relation is given as
[tex]\Rightarrow B=B_o(2)^\frac{t}{13}[/tex]
where, [tex]B=\text{No of bacteria at any time}[/tex]
[tex]B_o=\text{Intial bacterias}\\t=\text{time in hrs}[/tex]
for [tex]B=156[/tex]
[tex]\Rightarrow 156=100\times 2^{\frac{t}{13}}\\\\\Rightarrow 1.56=2^{\frac{t}{13}}\\\\\Rightarrow t=13\times \dfrac{\ln (1.56)}{\ln (2)}\\\\\Rightarrow t=13\times0.641=8.34\ hr[/tex]

i) For an given A.P. t7
= 4, d = -4 then a = . . .
Answer:
a = 28
Step-by-step explanation:
Given : t7= 4 , d = -4
Solution : tn = a + (n - 1) d ......( formula)
t7 = a + (7 - 1) (-4)
4 = a + (6)( - 4)
4 = a - 24
4 + 24 = a
28 = a
therefore, the first term (a) is 28.
Find angle x, giving your answer to 1 decimal place.
38°
х
11 cm
8 cm
Answer:
x = 55.8
Step-by-step explanation:
sinA/a + sinB/b
label any of them A (the angle) and opposite it will be a (the side)
[tex] \frac{ \sin(38) }{8} + \frac{ \sin(x) }{11} [/tex]
[tex]11 \times \frac{ \sin(38) }{8} [/tex]
(you can put ×11 the opposite area as well, it makes the same answer)
=0.84653452.....
[tex] \sin^{ - 1} (0.84653452)[/tex]
=57.83672257
Jason solved the equation below. What error did he make?
8 + 3x = 5(x - 2)
Step A: 8 + 3x = 5x – 10
Step B: 8 = 2x – 10
Step C: -2 = 2.c
Step D: -1= x
Answer:
It looks like on step c he took away 10 instead of adding 10

If you have $3250 how many board feet can you buy if the cost per board foot is $2.29?
Answer:
If i am right i think its 1419
Step-by-step explanation:
3250/2.29= about 1419
Answer:
1419.21= 1419
Step-by-step explanation:
Divide the amount of money you have with the cost price of what you want to buy.
$3250/$2.29=1419.213974
The answer is a decimal. But we can not have a unit as decimal so we have to round it down to the nearest whole number.
Therefore = 1419

James has collected 3985 stamps so far. He had 787 stamps from countries other than the United States. What percent of the stamps are from countries other than the United States?
Answer:
divide 787 by 3985 then multiply that by 100
Step-by-step explanation:
if it were 100 stamps total and 50 from non US countries, you could pretty easily tell it was half, or 50% to ge that you need to divide the number in question by the total so 50/100. which gets .5. to get the percent you multiply it by 100
so given the numbers we divide 787 by 3985 then multiply that by 100

Amanda has $40 to spend on flowers. She wants to buy a pair of red rose flowers for $18 and spend the rest on lly flowers. Each lily flower costs $11. Choose the inequality for the number of lly
flowers she can purchase:
o
A
11x + 18 5 40
B. 18x + 11 S 40
G
C. 11x + 18 < 40
D. 18x + 18 < 40
Answer:
[tex]11x + 18 \leq 40[/tex]
Step-by-step explanation:
She can buy x illy flowers, and each illy flower costs $11.
She wants to buy a pair of red rose flowers for $18 and spend the rest on lly flowers. Each lily flower costs $11.
This means that the total amount she will spend is:
[tex]18 + 11x[/tex]
Amanda has $40 to spend on flowers.
This means that her total spending can be at most $40, which means that:
[tex]11x + 18 \leq 40[/tex]
This is the inequality that models this situation.
Least the containers from least to greatest capacity; 1.73, 2.061, 1.59, 2.1
Answer:
1.59 < 1.73 < 2.061 < 2.1
Step-by-step explanation:
Hello,
We know that 2 is higher than 1. So to pick the first ones we know it won't be the two numbers starting with a 2. We are left with two numbers : 1.73 and 1.59. In this case we can multiply these two numbers by 100. We are allowed to do this only if we do it to all the numbers we are trying to figure out. In this case, it is 1.73 and 1.59 (we are excluding the 2s). So we end up with : 173 and 159. This might help you. We obviously know that 173 is a larger number than 159.
So, we then proceed to the numbers starting with a 2. In this case we can multiply both by 1,000 considering the fact that the number 2.061 has 3 digits after the dot. This will make it easier for us. When we multiply both by 1,000 we end up with 2,061 and 2,100. We obviously know that 2,061 is smaller than 2,100.
I hope this helped
Kind regards,
