Find the probability that x <-3
Answers
Answer:
Step-by-step explanation: if you want to obtain the probability that x [tex]\leq[/tex]-3 , then you need to add the probability for the cases x=-3 and x=-5.
p=0.13+0.17= 0.3
answer=0.3
The probability that x ≤ -3 will be the sum of 0.13 + 0.17 = 0.30.
What is probability?The probability of an event occurring is defined by probability.
Probability is also called chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
As per the given probability distribution.
The probability distribution is the probability of different cases.
In cases the probability adds thus,
P(x ≤ - 3) = P (x = -3) + P(x = -5)
⇒ 0.13 + 0.17 = 3
Hence "The probability that x ≤ -3 will be the sum of 0.13 + 0.17 = 0.30".

Answer:
D
Step-by-step explanation:
Its an abs value so you have to solve twice. Once for d - 3.5 < or equal to 1.5 which equals 5. You also have to solve for d - 3.5 > or equal to -1.5 which equals 2. So on the graph it has to be less than 5 and greater than 2 so you just connect the two and draw the line over the numbers in between the 2 and 5.

The most Julius can afford to pay per year in mortgage payments is $11,500,
and his credit score is currently 463. According to the following table for a
$150,000 mortgage, by how many points would he need to improve his credit
score in order to take a mortgage for $150,000?
Answers
Answer:
212 points
Step-by-step explanation:
He can only afford $11500 per year so divide that by 12, gets you 958 so he’s in the 675-699 range subtract 675- his current credit score to get the number of points he will need.

The value of a certain car after one year was $13,595. The value of the same car after 3 years was $11,095. Find the slope and explain what it means.
Answers
Answer:
-1250/1 or -1250
This tells us that the car depreciated in value by $1250 every year.
Step-by-step explanation:
11,095-13,595= -2500
This is the value that the car has depreciated over 2 years (from the first year to the third year)
Since we need to find the slope we divide this value by two.
That value would be -1250
Since the value is negative, we know the car has depreciated in value. We also now know that it depreciated in value by $1250 every year

Step-by-step explanation:
Assuming you want to find the value of n.
[tex]\sqrt{\frac{p}{q} } =(\frac{q}{p}) ^{1-2n} \\[/tex]
Remember when bases are same exponents can be made equal
Here the bases are different
because notice on one side there is p/q and on the other q/p
what can we do to make them same?
You can invert the any side you want either make leftside as q/p or make right one as p/q
I will make left side as q/p
All you do is flip the denominator and numerator to do so. But that can only be done if you put a (-1) in the exponent
so underroot p/q means (p/q)^1/2 when i make it q/p
a negative one needs to be put in the exponent. That -1 when multiplied by 1/2 makes it -1/2
Now the bases are same such like.
[tex](\frac{q}{p} )^{-1/2} = (\frac{q}{p}) ^{1-2n}[/tex]
See now the bases are same, the powers can be made equal
so
-1/2=1-2n
here n is the variable we need to find
rearrange the equation
n=3/4

Answer:
[tex]x=27[/tex]
Step-by-step explanation:
Notice that Angle A is being bisected.
Hence, we can use the Angle Bisector Theorem to write the following proportion:
[tex]\frac{x+8}{10}=\frac{2x-5}{14}[/tex]
Solve for x. Cross-multiply:
[tex]10(2x-5)=14(x+8)[/tex]
Distribute:
[tex]20x-50=14x+112[/tex]
Subtract 14x from both sides:
[tex]6x-50=112[/tex]
Add 50 to both sides:
[tex]6x=162[/tex]
Divide both sides by 6. Hence, the value of x is:

The total earning of commission on sales of 85, 000 will be:
[tex]3500+1050=4550[/tex]
Step-by-step explanation:
Total sales earning = 85,000As salesperson earns 5% commission the first 70,000.
[tex]\frac{5}{100}\:\times \:70\:000=3500[/tex]
As the salesperson earns 7% commission on the sales over 70,000.
As 15000 is the sales earning on which he will get commission 7%.
Because
85,000 - 70,000 = 15000So the 7% earning of salesperson will on 15000 will be:
[tex]\:\frac{7}{100}\:\times \:15\:000=1050[/tex]
Therefore, the total earning of commission on sales of 85, 000 will be:
