Answers
Answer:
same amount of money
Step-by-step explanation:
The unit rate for a 9-ounce jar is $0.17.
The unit rate for a 15-ounce jar is $0.17.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
The store sells a 9-ounce jar of mustard for $1.53.
The unit rate.
= 1.53/9
= 0.17 _____(1)
The store sells a 15-ounce for $2.55.
The unit rate.

for B it is asking for probability of 3 and it is 1/2 of and 1/4 of the circle so 1/8
for C it is asking for probability of the odd numbers and there is tow odd numbers 1 and 3 the probability of 1 is 1/2 and the probability of 3 is 1/8 adding them up will give you 5/8
for d it asks for the probability of at least 2 so therefor 2, 3, and 4 and they are 1/8 + 1/8 + for 1/4 = 1/2

Answer:

Step-by-step explanation:
7 3/10 - 3 9/10=
In this case 3/10 - 9/10 is cannot be so we have to borrow 1 whole from 7
so, 7 3/10 will become 7 3/10 + 1 or to add we have to change 1 as 10/10, any way 1 and 10/10 is equal but in this case we will use 10/10 to add 1 whole to 3/10 and minus 1 whole to 7
so, 3/10 + 10/10 = 13/10
and 7 - 1 = 6
so, 7 3/10 as 6 13/10
any way 7 3/10 and 6 13/10 is equal but, in this case we have to use 6 13/10 to minus, because 7 3/10 is cannot be
so, 6 13/10 - 3 9/10 =

Which of the inequalities is/are true
Gary: [tex]6>0.5t[/tex]

A water balloon was launched into the top of the hill 38 feet above the ground
Answers
Answer: -71.104 ft/sec
Step-by-step explanation:So you need to know how fast the balloon is moving when it hits this person's head. velocity is based on time. So you need the time that it hits this person's head. You can get time from the position equation. Because the balloon hits this person's head 6 feet from the ground, you know that the final position is at 6 so you plug that into the position equation and solve for t. You look and see what the appropriate t value is and plug it into the velocity equation and see what the answer is.
6=-16t^2+40t+60
0=-16t^2+40t+54
plug in those values into the quadratic formula or your calculator and you get:
t = -.972
or
t = 3.472
since you can't have negative time, the other answer must be it.
So you then plug it in and solve.
v(3.472) = -32(3.472) + 40
which is approximately -71.104 ft/sec
or if they just want speed, 71.104 ft/sec. (remember, speed is velocity without direction)
The circumference of a circular island is 34.54 miles. What is the area of the
island?
Answers
Answer:
A = 94.99
Step-by-step explanation:
C = 2(3.14)r
34.54 = 2(3.14)r
34.54 = 6.28r
r = 34.54/6.28
r = 5.5
A = (3.14)r²
A = (3.14)5.5²
A = (3.14)30.25
A = 94.985
Answer:
95miles²
Step-by-step explanation:
The circumference of a circular island = 34.54 miles.
2πr=34.54miles
πr=17.27mile
r=17.27/πmile
the area of the island=πr²=π×{17.27/π}²=95miles² approx

What expression is equivalent to 16 + 2 ⋅ 36?
Answers
to figure this one out we need to simplify the expression
16x²-36 start by taking out the greatest factor of 16 and 36 which is 4
4(4x²-9) then since this is the difference of squares (meaning both 4 and 9 are squares and it is subtraction) this one is easy, just square the parenthasis and seperate them to get
4(2x+3)(2x-3)
I hope I've helped!
The expression [tex]\rm 16x^2-36[/tex] is equivalent to 4(2x+3)(2x-3).
It is given that the expression [tex]\rm 16x^2-36[/tex]
It is required to simplify this expression.
What is polynomial?Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.
We have an expression:
[tex]=\rm 16x^2-36[/tex]
As we can see in the above expression we can take out 4 because 4 is the common factor of 16 and 36.
[tex]=\rm 4(4x^2-9)[/tex] or we can write it as:
[tex]\rm = 4((2x)^2-3^2)[/tex]
We know that the:
[tex]\rm (a^2-b^2) = (a+b)(a-b)[/tex]
By using the above formula, we get:
[tex]\rm = 4(2x+3)(2x-3)[/tex]
Thus, the expression [tex]\rm 16x^2-36[/tex] is equivalent to 4(2x+3)(2x-3).

12.32 11.87 12.34 11.48 12.66
8.51 14.13 12.95 9.34 8.63
Required:
a. Construct a interval for the mean weight of two-month-old baby girls.
b. According to the National Health Statistics Reports, the mean weight of two—month-old baby boys is 13.9 pounds. Based on the confidence interval, is it reasonable to believe that the mean weight of two-month—old baby girls may be the same as that of two-month-old baby boys? Explain.
Answers
Answer:
10.224 < μ < 12.622 ;
Since the mean weight of 2-montj old baby boys (13.9) falls outside the confidence interval, we can conclude that it is not reasonable to believe that the mean weight of two-month-old baby girls may be the same as that of two-month-old baby boys.
Step-by-step explanation:
The confidence interval is given as :
Mean ± Margin of Error
margin of error = Zcritical * standard deviation /sqrt(n)
n = sample size
From the data:
12.32, 11.87, 12.34, 11.48, 12.66, 8.51, 14.13, 12.95, 9.34, 8.63
From the data:
Using calculator :
Mean, = 11.423
Standard deviation, s = 1.934
Zcritical at 95% confidence interval = 1.96
Sample size, n = 10
Margin of Error = 1.96* 1.934/sqrt(10) = 1.199
Lower boundary = 11.423 - 1.199 = 10.224
Upper boundary = 11.423 + 1.199 = 12.622
10.224 < μ < 12.622
Since the mean weight of 2-montj old baby boys (13.9) falls outside the confidence interval, we can conclude that it is not reasonable to believe that the mean weight of two-month-old baby girls may be the same as that of two-month-old baby boys.
