Sandy spun a spinner with 5 equal parts labeled 1-5. What is the probability she will Not spin a 4
The probability that she will not spin a 4 will be 0.80 or 4/5.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
Sandy spun a spinner with 5 equal parts labeled 1-5. Then the total number of events will be given as,
Total events = 5 {1, 2, 3, 4, 5}
Then the favorable events are given as,
Favorable events = 4 {1, 2, 3, 5}
Then the probability is given as,
P = 4 / 5
P = 0.80
The probability that she will not spin a 4 will be 0.80 or 4/5.

Final answer:
The probability that Sandy will not spin a 4 on a spinner with 5 equal parts is 4/5 or 80%. There are 4 favorable outcomes and 5 possible outcomes in total.
Explanation:
The question asks for the probability that Sandy will not spin a 4 on a spinner that's divided into 5 equal parts, each labeled with the numbers 1-5. Since there are 5 outcomes and only one of them is the one we want to avoid, that leaves us with 4 favorable outcomes (spinning a 1, 2, 3, or 5). The probability of not spinning a 4 is therefore the number of favorable outcomes (not spinning a 4) divided by the total number of possible outcomes (spinning any number from 1 to 5).
To calculate this, we divide the favorable outcomes by the total number of outcomes. This gives us a probability of 4/5, or 80%. The calculation is as follows:
Number of favorable outcomes: 4 (spinning a 1, 2, 3, or 5)Total number of outcomes: 5 (spinning any number from 1 to 5)Therefore, P(not spinning a 4) = 4 favorable outcomes / 5 total outcomes = 4/5 or 0.8, which means there is an 80% chance that Sandy will not spin a 4.

Step-by-step explanation:
The expression for the pressure in terms of force is as follows;
[tex]P= \frac{F}{A}[/tex]
Here, F is the force, P is the pressure and A is the area.
It is given in the problem that an object exerts 140 N of force on a surface that has an area of 2.0 meter square.
Put F= 140 N and A= 2 meter square in the above expression.
[tex]P= \frac{140}{2}[/tex]
[tex]P= 70 N/m^2[/tex]
Therefore, the pressure exerts on the object is 70 N/m^2.
The motion of air particles inside an inflated balloons:
In the inflated balloons, the molecules of air are far apart. These molecules are in random motion. They collide each other inside the surface of the balloons. The pressure will be exerted by the air molecules on the surface of the balloons. The pressure caused by atmospheric molecules collides with the outside the surface is equal to the pressure caused by atmospheric molecules collides with inside the surface of the inflated balloons. Therefore, the volume of the balloons remains constant.

You deposit $350 in a savings account. The account earns 2.5% simple interest per year. What is the balance after 2 years?
Answer:
Balance = $367.5
Step-by-step explanation:
The 2.5% of $350 is,
→ (350/100) × 2.5
→ 3.5 × 2.5
→ $8.75
The balance after 2 years is,
→ $350 + (2.5%) × 2 years
→ 350 + 8.75 × 2
→ 350 + 17.5
→ $367.5
Hence, the answer is $367.5.
The balance after 2 years on principle amount of $350 at the rate of 2.5% will be $525.
What is Simple interest?The simple interest method, which adds interest to the starting principal amount at the same rate every day, is a quick and easy technique to calculate the interest on that money.
Simple interest is a way to calculate the amount of interest that will be charged on a certain amount of money at a certain rate and for a certain period of time.
As per the information in the question,
Principle amount, p = $350
Rate, r = 2.5%
Time, t = 2 years.
Use the formula of simple interest,
[tex]S.I = (p*r*t)/100[/tex]
S.I = (350 × 2.5 × 2)/100
S.I = 17500/100
S.I = 175
Now, the total amount will be,
$350 + 175 = $525

the elevation of Denver Colorado is 13 times greater than that of waikapu. hawaii.the sum of their elevations is 5600 ft. find the elevation of each city
Answer:
400ft
Step-by-step explanation:
The elevation of Waikapu, Hawaii is 400 feet, and the elevation of Denver, Colorado is 5200 feet, derived from a simple algebraic equation based on their given relationship and sum of elevations.
We are given that the elevation of Denver, Colorado is 13 times greater than that of Waikapu, Hawaii, and the sum of their elevations is 5600 ft. To find the elevation of each city, we can set up a system of equations.
Let x represent the elevation of Waikapu, then the elevation of Denver is 13x. According to the problem, we can set up the equation as follows:
x + 13x = 5600
Combining like terms gives us:
14x = 5600
Dividing both sides by 14 to isolate x gives us:
x = 5600 / 14
x = 400
Now that we have the elevation of Waikapu, we can find Denver's elevation by multiplying 400 by 13:
Denver's elevation = 13 x 400 = 5200 ft
Therefore, the elevation of Waikapu, Hawaii is 400 feet, and the elevation of Denver, Colorado is 5200 feet.

What is the sixth term in the binomial expression (5y+3)^10
Answer : The sixth term in the binomial expression is, [tex]^{10}C_5a^{5}b^{5}[/tex]
Step-by-step explanation :
The general formula to calculate the term of binomial expression is:
[tex]T_(r+1)=^nC_ra^{(n-r)}b^r[/tex]
where,
(r+1) = number of term
As we are given the binomial expression :
[tex](5y+3)^{10}[/tex]
For sixth term :
a = 5y
b = 3
n = 10
As, r + 1 = 6
So, r = 6 - 1
r = 5
Now put all the given values in the above formula, we get:
[tex]T_(r+1)=^nC_ra^{(n-r)}b^r[/tex]
[tex]T_(5)=^{10}C_5a^{10-5}b^5[/tex]
[tex]T_(5)=^{10}C_5a^{5}b^{5}[/tex]
Thus, the sixth term in the binomial expression is, [tex]^{10}C_5a^{5}b^{5}[/tex]

Fiona earns $15 for each lawn she mows. Which inequality can be used to find out how many lawns she must mow to earn at least $135?
Final answer:
Fiona needs to mow at least 9 lawns to earn at least $135, represented by the inequality 15L ≥ 135, where L is the number of lawns mowed.
Explanation:
To determine how many lawns Fiona must mow to earn at least $135, we can set up an inequality. Fiona earns $15 for each lawn she mows, therefore if we let L represent the number of lawns mowed, then Fiona's earnings can be represented by 15L. She needs to earn at least $135, so we can write the inequality as 15L ≥ 135. To find L, we divide both sides of the inequality by 15, which gives us L ≥ 9. Therefore, Fiona must mow at least 9 lawns to earn at least $135.

Horace buys 2/4 pounds of blueberries48 ounce of blueberries needed for a pieTo determine how many pounds of blueberries that Horace need to buy, we have to convert ounces because this mathematical question is related to unit conversion.Further Explanation1 pounds = 16 ounces, therefore,
3 pounds = 48 ounces (we multiply 16 and 3 = 48)
To find how many pounds he need to by = 3 ounces – [tex]\frac{2}{4}[/tex]
= 3 – [tex]\frac{2}{4}[/tex]
= [tex]\frac{3}{1}[/tex] – [tex]\frac{2}{4}[/tex] (4 is the smallest number can divide both denominator) therefore, we have
= (4 x 3) – (1 x 2) / 4
= 12 - 2 / 4
