Alex scored 98,72, and 87 on his first three math test. What must he score on the next test to have an average of at least 86 (P.S I need quickly no need to rush yourself just quickly)
Answer:
[tex]\huge\boxed{\text{At least an } 87\%}[/tex]
Step-by-step explanation:
In order to find what score Alex must earn to have an average of 86 on all his tests, we need to first note what the formula to find the average of a data set is.
[tex]\displaystyle \frac{x_1+x_2+...x_n}{n}[/tex]
What the formula means is that we have to add up all the values then divide by the total number of values.
Let's represent our unknown number as [tex]x[/tex].
[tex]\displaystyle \frac{98+72+87+x}{4} \geq 86[/tex] (since we want AT LEAST an 86).
Let's solve this inequality for x.
[tex]\frac{98+72+87+x}{4} \cdot 4 \geq 86 \cdot 4[/tex] [tex]98+72+87+x \geq 344[/tex] [tex]257 + x \geq 344[/tex] [tex]257 + x - 257 \geq 344 - 257[/tex] [tex]x \geq 87[/tex]So, Alex must score at least an 87% on his next quiz to have an average of 86%.
Hope this helped!
What’s the process for finding c in this equation?
Answer:
x = 7
Step-by-step explanation:
Given that ∆BCD ~ ∆BFG, therefore the ratio of their corresponding side lengths will be equal.
Thus:
[tex] \frac{BC}{BF} = \frac{BD}{BG} [/tex]
Substitute
[tex] \frac{17x + 13}{36} = \frac{154}{42} [/tex]
Cross multiply
[tex] 42(17x + 13) = 154(36) [/tex]
[tex] 714x + 546 = 5,544 [/tex]
[tex] 714x = 5,544 - 546 [/tex] (subtraction property of equality)
[tex] 714x = 4,998 [/tex]
Divide both sides by 714
x = 7

A manufacturer tests a certain number of headsets that are produced each day. There is a 2% chance of finding a defective headset. If 280 units of that model are tested,the manufacturer would expect to find approximately how many head sets without any defects
Answer:
Correct headsets= 274.4 = 274
Step-by-step explanation:
Giving the following information:
Number of units= 280
There is a 2% chance of finding a defective headset.
To calculate the number of headsets without any defect, we need to use the following formula:
Correct headsets= 280*0.98
Correct headsets= 274.4 = 274

Ramon buys 3.5 pounds of strawberries for $8.75. At this rate, how many pounds of strawberries can Allison buy with $20.00?
Answer:
8 pounds
Step-by-step explanation:
8.75 / 3.5 = 2.5
20/2.5 = 8
Answer: 8 pounds of strawberries
Step-by-step explanation:
$8.75 - 3.5 pound
? - 1 pound
1 pound - 8.75 ÷ 3.5 = 2.5
$2.50 = 1 pound
$20.00 = ?
$20 = 20 ÷ 2.5 = 8
$20.00 = 8
Allison can buy 8 pounds of strawberries with $20.00

Cat behavior: A report stated that the average number of times a cat returns to it's good bowl during the day is 37. Assuming the variable is normally distributed with a standard deviation of 3, what is the probability that a cat would return to it's dish between 34 and 39 times a day. Use the graphing calculator. Round the answer to four decimal places.
P (34<X<39) =?
Answer:
P (34<X<39) = 0.5899
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 37, \sigma = 3[/tex]
What is the probability that a cat would return to it's dish between 34 and 39 times a day.
This is the pvalue of Z when X = 39 subtracted by the pvalue of Z when X = 34. So
X = 39
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{39 - 37}{3}[/tex]
[tex]Z = 0.67[/tex]
[tex]Z = 0.67[/tex] has a pvalue of 0.7486
X = 34
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{34 - 37}{3}[/tex]
[tex]Z = -1[/tex]
[tex]Z = -1[/tex] has a pvalue of 0.1587
0.7486 - 0.1587 = 0.5899
So
P (34<X<39) = 0.5899
SOLVE FOR Y, WILL GIVE BRAINLIEST
Step-by-step explanation: Notice that the angle diagonal
of the 114° is a vertical angle and vertical <'s are ≅.
Now, notice that we have two parallel lines cut by a transversal.
If two parallel lines are cut by a transversal, then
consecutive interior angles are supplementary.
So we can setup the equation 114 + y + 12 = 180.
Simplifying on the left gives us 126 + y = 180.
Now subtract 126 from both sides to get y = 54.
Write the equation below in standard form.
[tex] \frac{8}{3}y = \frac{5}{6}x - 2 [/tex]

Apples are on sale at four different grocery stores. Which store offers the
lowest unit rate for apples, in dollars per pound?
$4.50
.McCoyS Dounds
$
• Greenland :
pound
$3.00
2 pounds
Eat Smart
• Mother Nature: S0.95/pound
OA. McCoy's
OB. Eat Smart
OC. Mother Nature
OD. Greenland
Full question attached
Answer:
Greenland offers the lowest unit rate, dollars per pound
Step-by-step explanation:
For McCoy, $4.5 = 5 pounds
Therefore $1 = 5pounds/4.5= 1.11 pounds
1 pound= 1/1.11= $0.9009
For Eat smart
$3=2 pounds
Therefore $1=2pounds/3 = 0.667 pounds
1 pound = 1/0.667= $1.499
For Greenland
$1/5= 1/4 pounds
$0.2=0.25 pounds
$1= 1.25 pounds
Therefore 1 pound= 1/1.25= $0.8
For Mother Nature
$0.95= 1 pound
Therefore Greenland offers the lowest unit rate at $0.8 per pound
g+5>12 solution please i don’t know how to do this
Answer: g > 7
Graph has an open circle at 7 on the number line, shading to the right
================================================
Explanation:
Think of it like saying "I have a number, and I add on 5. The result is something larger than 12". You can guess and check your way to the answer, but the quickest way is to subtract 5 from both sides.
We subtract to undo the addition happening to the 'g'.
g+5 > 12
g+5-5 > 12-5
g > 7
So the number is larger than 7. For instance, if g = 8, then,
g+5 > 12
8+5 > 12
13 > 12
This is a true statement.
-------------------------
If you need to graph the solution, then you'll have an open circle at 7 on the number line. The open circle says to the reader "don't include this value as part of the solution set". Shade to the right of the open circle to describe all values larger than 7.
In summary, the graph has an open circle at 7 and shading to the right.
