If you roll a single dice one time, what is the probability of rolling a 7 ?
Answer:
1/7
Report if wrong :)
Step-by-step explanation:
Also, I plead the 5th
Answer and Step-by-step explanation:
The probability of rolling a single 6-sided dice one time is 0% or 0/6.
This is because 7 is not a number/side on a 6-sided die.
If the single dice has 7 sides, then it would be 1/7 chance.

2. Priscilla is drawing a map of her school that uses a scale in which 1.5 cm 1 point
on the map represents 3 ft. If the first hallway has a length of 120 ft, what
should the length of the hallway be on the map?
O
a. 40 cm
b. 60 cm
C. 30 cm
d. 45 cm
Answer:
The answer is 60cm. (b)
Step-by-step explanation:
For every 1.5cm on the map, it represents 3 ft on real-size scale.
In other words, for every 1cm on the map, it represents 3/1.5 = 2ft on real size scale.
If you want to find 120ft of real-size scale, you can use 120ft/2ft * 1cm which gives 60cm

A study of the effects of acid rain on trees in the Hopkins Forest shows that 25 of 100 trees sampled exhibited some sort of damage from acid rain. This rate seemed to be higher than the 15% quoted in a recentEnvironmetricsarticle on the average proportion of damaged trees in the Northeast. Does the sample suggest that trees in the Hopkins Forest are more susceptible than trees from the rest of the region
Answer:
Yes
Step-by-step explanation:
We can test this claim using the one proportion z test :
x = 25 ; n = 100
Phat = x / n = 25 / 100 = 0.25
H0 : P = 0.15
H0 : P > 0.15
The test statistic :
Z = (phat - p) ÷ √p(1-p)/n
Z = (0.25-0.15) ÷ √(0.15*0.85)/100
Z = 2.8
Using the Pvalue from Zscore calculator :
α = 0.05
Pvalue (Z < 2.8) =0.0026
Pvalue < α ; We reject the Null

Write the equation of the line parallel to y=2x+7 and contains the points (6,-1)
Answer: y = 2x - 13
Step-by-step explanation: Start with the formula y=mx+b. Remember that the slope of the parallel line, m, is the same. Now you have y = 2x + b. You can find b, the y intercept, knowing that the line passes through the point given: -1 = (2) * 6 + b. So now we see that b = -13.

Heidi solved the equation 3(x + 4) + 2 = 2 + 5(x – 4). Her steps are below: 3x + 12 + 2 = 2 + 5x – 20 3x + 14 = 5x – 18 14 = 2x – 18 32 = 2x 16 = x Use the drops-downs to justify how Heidi arrived at each step. Step 1: distributive property Step 2: Step 3: Step 4: Step 5:
Answer:
See explanation
Step-by-step explanation:
3(x + 4) + 2 = 2 + 5(x – 4)
Step 1: distributive property
3(x + 4) + 2 = 2 + 5(x – 4)
3x + 12 + 2 = 2 + 5x - 20
Step 2: collect like terms
3x + 12 + 2 = 2 + 5x - 20
3x + 14 = 5x - 18
Step 3: Addition property of equality
3x + 14 = 5x - 18
3x + 14 + 18 = 5x - 18 + 18
3x + 32 = 5x
Step 4: subtraction property of equality
3x + 32 - 3x = 5x - 3x
32 = 2x
Step 5: division property of equality
32 = 2x
32/2 = 2x/2

Jim took out a loan for $500 . The rate is 8%. How much does Jim owe in interest if he plays it back in 4 1/2 years?
What is the balance that jim owes for his loan?
Answer:
If jim pays the loan back in 4 1/2 years he will be paying $597.03
Step-by-step explanation:
As per simple interest, Jim owes $180 in interest.
Jim owes a balance of $680 for his loan.
What is a simple interest?"By definition, simple interest is the interest amount for a particular principal amount of money at some rate of interest."
Given, the loan amount is P = $500.
The rate of interest is i = 8% = 0.08.
The duration is [tex]4\frac{1}{2}[/tex] years t = 4.5 years.
Therefore, the interest after the mentioned period
= (P × i × t)
= $(500 × 0.08 × 4.5)
= $180
Therefore, Jim owes $180 in interest if he pays it back in mentioned time period.
The balance that Jim owes for loan is
= $(500 + 180)
= $680

John writes a number sequence starting with 8. Write the next number 8, 22, 36, _______
Answer:
50
Step-by-step explanation:
from the question that we have been given, we have to find out the next number after 36.
John's next number sequence will be 50. Every number after 8 can be gotten by adding 14. So when we add 14 to 36, we get the final answer, which is the next number in the sequence.
This can be seen below:
14 + 8 = 22
14 +22 =36
14 +36 =50
therefore the next sequence would be 50

Answer:
148cm²
Step-by-step explanation:
With the first frontal face of the cuboid, you have length 6 cm whilst the height remains 5 cm.
Find the area of this face and multiply the result by 2, as there are two of these faces (front and back)
6 x 5 = 30 cm²
30 x 2 = 60cm²
Do the same with the top face and bottom face, adding this with the side faces
4 x 6 = 24cm²
24 x 2 = 48cm²
4 x 5 = 20cm² x 2 = 40 cm²
40 + 48 + 60 = 148 cm²
T.S.A = 148cm²

Can somebody plz help draw the spinner with these probabilities on the question like take a pic of how it looks like or explain how I do it? Thanks!
I will draw a rough figure, you can draw it neatly.
Probability =
Probability = No. of favourable outcomes/ Total no. of outcomes
Probability = No. of favourable outcomes/ Total no. of outcomesTotal number of outcomes = 4
So, here:
P(2) = 2/4 = 1/2
P(1) = 1/4
P(3) = 1/4
P(4) = 0
Here, the probability of getting 2 is ½.
Probability of getting 1 is ¼.
Probability of getting 3 is ¼.
Probability of getting 4 is 0.
