S Slitsnails are large mollusks that live in deep waters. They have been found in the range of elevations $e$ shown.
A photo shows elevations under water. The range of elevations extends from negative 100 feet to negative 2500 feet.
Write the compound inequality that represents this range.
The range could be written in inequality form will be:
-2500 ≤ x ≤ -100.
Living in the deep sea are slitsnails. It is assumed that they inhabit depths ranging from 100 to 2500 feet.
Let x represents the distance between the water and the surface.
The depth will decrease as we sink further into the water.
Therefore, the depth could range from 100 to 2500 feet.
The maximum depth is 2500 feet, and the lowest depth should be 100 feet.
So, the range could be expressed as follows in inequality form:
-2500 ≤ x ≤ -100.
Hence the required compound inequality is framed.

Two angles of a triangle have the same measure and the third one is 48 degrees greater than the measure of each of the other two. Find the measure of the LARGEST angle in the triangle.
Answer: The LARGEST angle has a measure of
degrees.
The LARGEST interior angle of the triangle has a measure of 92 degrees.
What is the largest angle of the triangle?The sum of the interior angle of a triangle is 180 degrees.
Given the data in the question;
Let x represent the measure of the first two angles.
Since they have same measurements.
Measure of angle 1 = xMeasure of angle 2 = xMeasure of angle 3 = x + 48Since the sum of the interior angle of a triangle is 180 degrees.
m∠1 + m∠2 + m∠3 = 180°
x + x + x+48 = 180
3x + 48 = 180
3x = 180 - 48
3x = 132
x = 132/3
x = 44°
Measure of the largest angle will be;
Measure of angle 3 = x + 48 = 44 + 48 = 92°
Therefore the LARGEST interior angle of the triangle has a measure of 92 degrees.

You consider buying a phone from one of two cell phone carriers. The table shows the total costs (in dollars) of the phone and service for different numbers of months at Carrier A. The total cost $y$y (in dollars) of the phone and x$x$x months of service at Carrier B is represented by the equation y is equal to 55 x plus 300$y=55x+300$y=55x+300 . Which carrier has the lower initial fee?
Answer:
Carrier B
Step-by-step explanation:
The linear equation that represents Carrier B is y=55x+300. it's a linear equation so 55 represent the monthly fee and 300 represents the initial fee. So the initial fee of carrier B is 300. In case of Carrier A, the total cost increases by $150 as months increases by 3. So The initial fee of Carrier A is 500-150=$350 . Hence, Carrier B has lower initial fee.

Késhaun conducted an experiment using a toy car and ramps of various
heights. He measured the distance, in centimeters (cm), the toy car
traveled from the end of the ramp. He also recorded the height, in
centimeters (cm), of the ramp. He found that the toy car traveled 64 cm
when the ramp height was 15 cm. The toy car traveled 112 cm when the
ramp height was 26 cm.
Write the equation of the line, in standard form, where x represents the
ramp height, in cm, and y represents the distance, in cm, the toy car
travels.
Step-by-step explanation:
we have 2 points on the line :
(15, 64) and (26, 112)
the standard form I assume is the slope-intercept form :
y = ax + b
"a" being the slope, "b" being the y-intercept (the y value when x = 0).
the slope is the ratio (y coordinate difference / x coordinate difference) when going from one point on the line to another.
the direction does not matter, but when picking one for one coordinate difference calculation, we have to use the same direction for the other.
I prefer to go from left to right.
so, in our case here
x changes by +11 (from 15 to 26).
y changes by +48 (from 64 to 112).
the slope "a" is +48/+11 = 48/11
so, our equation looks already like this :
y = 48/11 x + b
now, we use any of our points to get b.
let's pick (15, 64) :
64 = 48/11 × 15 + b = 720/11 + b
704/11 = 720/11 + b
-16/11 = b
and our full equation is
y = 48/11 x - 16/11
or
y = 1/11 × (48x - 16/11)
or
y = 16/11 × (3x - 1)

At age 20, a person deposits $395 in a savings account paying 1% interest compounded quarterly. How much money will be in the account 60 years later, when he is 80 years old? Would his savings have tripled in that time?
The amount in the account after 60 years is $719.
His saving has not tripled after 60 years.
What is compound interest?
Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods.
We have,
Principal = $395
Rate = 1%
Number of years = 60
The amount compounded quarterly is given by:
A = P [ 1 + (R/4)/100 [tex]]^{4n}[/tex]
P = principal
R = rate
n = number of years
A = 395 [ 1 + 1/400 [tex]]^{4 \times{60}}[/tex]
A = 395 [ 1 + 1/400 [tex]]^{240}[/tex]
A = 395 [ 1 + 0.0025 [tex]]^{240}[/tex]
A = 395 [ 1.0025 [tex]]^{240}[/tex]
A = 395 x 1.8207549953165
A = 719.19625
A = $719
Thus the amount in the account after 60 years is $719.
His saving has not tripled after 60 years.

Find the angle of elevation of the sun from the ground to the top of a tree when a tree that is 10 yards tall casts a shadow 14 yards long. Round to the nearest degree.
Answer:
Approximately [tex]36^{\circ}[/tex], assuming that the tree is upright.
Step-by-step explanation:
Refer to the diagram attached. The upright tree and its shadow are in a right triangle. In this right triangle, the angle of elevation of the sun would be the angle adjacent to the shadow of this tree. At the same time, this angle would be opposite to the side representing the tree. Thus, the tangent of this angle could be represented as:
[tex]\begin{aligned}\tan(\text{angle of elevation}) &= \frac{\text{opposite}}{\text{adjacent}} \\ &= \frac{10\; \text{yard}}{14\; \text{yard}} \\ &= \frac{5}{7}\end{aligned}[/tex].
Take the arctangent of this value to find the measure of this angle:
[tex]\begin{aligned} (\text{angle of elevation}) &= \arctan(\tan(\text{angle of elevation})) \\ &= \arctan\left(\frac{5}{7}\right) \\ &\approx 0.620 \times \frac{360^{\circ}}{2\, \pi} \\ &\approx 36^{\circ}\end{aligned}[/tex].
Thus, the angle of elevation of the sun at this moment would be approximately [tex]36^{\circ}[/tex].

To find a baseball pitcher's earned run average (ERA), you can use the formula El=9r, in which E
represents ERA, I represents the number of Innings pitched, and r represents the number of earned runs allowed.
Solve the equation for E. What is a pitcher's ERA if he allows 15 earned runs in 36 innings pitched?
If necessary, round your answer to the nearest hundredth.
The equation for E is E= _____?
If a pitcher allows 15 earned runs in 36 innings, then the ERA= ____?
The value of the ERA is the 3.75.
According to the statement
We have to find that the value of the ERA.
So, For this purpose, we know that the
ERA is the number which represents the average number of earned runs given up by the pitcher per nine innings.
From the given information:
First, we are given the formula E * i = 9 * r.
Second, we are asked to resolve for E. If i doesn't equal zero, then we are able to divide both side of this equation by i. (Note that i = the quantity of innings pitched, which isn't zero.) We then have the equation E = (9 * r) / i.
Third, we are given some numerical values for our variables, and asked to use this equation to unravel for E.
Substituting r = 15 (earned runs allowed) and that i = 36 (innings pitched) into the equation and that we have
E = (9 * 15) / 36 = 3.75 (rounded to the closest hundredth)
So, The value of the ERA is the 3.75.

Question 4 options: If random variable X has a binomial distribution with n =10 and P(success) = p =0.6, find the probability that X is more than 3. (That is, find P(X>3)
The probability that X is more than 3 i.e. P(x > 3) is 0.945
How to find the probability that X is more than 3?The given parameters are
Number of experiments, n = 10Number of success, x > 3Probability of success, p = 0.6The probability that X is more than 3 can be calculated using the following equation
P(x <= 3) + P(x > 3) = 1
So, we have
P(x > 3) = 1 - P(x <= 3)
This gives
P(x > 3) = 1 - P(0) - P(1) - P(2) - P(3)
The individual probabilities are calculated using
P(x) = C(n,x) * p*x * (1 -p)^(n-x)
So, we have
P(0) = C(10,0) * 0.6^0 * (1 -0.6)^(10 - 0) = 0.0001
P(1) = C(10,1) * 0.6^1 * (1 -0.6)^(10 - 1) = 0.00157
P(2) = C(10,2) * 0.6^2 * (1 -0.6)^(10 - 2) = 0.01062
P(3) = C(10,3) * 0.6^3 * (1 -0.6)^(10 - 3) = 0.04247
So, we have
P(x > 3) = 1 - 0.0001 - 0.00157 - 0.01062 - 0.04247
Evaluate
P(x > 3) = 0.945
