Answer:
-62.5008
Step-by-step explanation:
Find the pattern first: -75/15 = -5
Find the first 7 terms: -3/-5, 3/25, -3/125, 3/625
Add: -62.5008
Answer:
-62.5008
Step-by-step explanation:
The terms form a geometric sequence with first term -75 and common ratio -1/5. The sum of n terms of such a sequence is...
Sn = a1(1 -r^n)/(1 -r)
For the values of a1, r, and n, this sum is ...
S7 = -75(1 -(-1/5)^7)/(1 -(-1/5)) = -75(1 +1/78125)/(1 +1/5)
= -75(13021/15625) = -62 313/625
= -62.5008
The sum of the first 7 terms of the sequence is -62.5008.
Here are the first five terms of an arithmetic sequence. 4 9 14 19 24 Find, in terms of n, an expression for the nth term of this sequence
Answer:
The nth term can be represented by;
Tn = 5n- 1
Step-by-step explanation:
In this question, we are concerned with finding an expression in terms of n for then the term of the sequence.
Mathematically, the nth term of a sequence Tn can be represented by the formula;
Tn = a + (n-1)d
where a is the first term in the sequence which is 4 , and d is the common difference which is the difference between 2 consecutive terms which is 9-4= 5
our n is n, since we do not know the number of terms we are finding for
Plugging these values, we have;
Tn = 4 + (n-1)5
Tn = 4 + 5n -5
Tn = 5n- 1
What is the value of s3 when: (infinite geometric series)
The value of S₃ is 65/9.
what is a geometric series?A geometric series is the sum of an infinite number of terms that have a constant ratio between successive terms. S= a + ar + ar² + ar³+ . . .
a=start term r =common ratio
Given here, the nth term is 5(1/3)ⁿ⁻¹
therefore the sum of the first 3 terms of the geometric series is
S₃ = 5(1/3⁰) +5(1/3)¹+5(1/3)²
= 1+ 5/3 + 5/9
= 65/9
Hence the final answer is 65/9

A rocket is launched from atop a 104-foot cliff with an initial velocity of 110 ft/s. A. Substitute the values into the vertical motion formula . Let h = 0. B. Use the quadratic formula find out how long the rocket will take to hit the ground after it is launched. Round to the nearest tenth of a second.
Answer:
7.68 s
Step-by-step explanation:
The vertical motion formula is:
[tex] h_{t} = h_{0} + v_{0}t - \frac{gt^{2}}{2} [/tex]
Where:
h(t): is the final height = 0
h(0): is the height of the cliff = 104 foot
v(0): is the initial velocity = 110 ft/s
g: is the gravity = 9.8 m/s² = 32.15 ft/s²
Hence, from the vertical motion formula we can find the time that will take the rocket to hit the ground:
[tex] 0 = 104 + 110*t - \frac{32.15t^{2}}{2} [/tex]
[tex] 0 = 104 + t(110 - 16.08t) [/tex]
We have two solutions:
t₁= -0.84 s
t₂ = 7.68 s
We will take the positive value, thus the time that will take the rocket to hit the ground is 7.68 s.

Keiko uses 8.8 pints of white paint and blue paint to paint her bedroom walls. 4/5 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answer:
1.76pints of blue paintStep-by-step explanation:
The total number of paint used = 8.8pints
If 4/5 of this amount is white paint, then the amount of white pint is expressed as;
[tex]= \frac{4}{5}*8.8\\= \frac{35.2}{5}\\[/tex]
= 7.04
This means the amount of white paint used is 7.04pints.
amount of blue paint used = Total amount of paint - amount of white paint
amount of blue white paint used = 8.8 - 7.04
amount of blue paint used = 1.76pints of paint

James, a real estate appraiser is looking at homes in the 78681 zip code. He takes a random sample of 42 homes form the Austin MLS (that's where Realtors go for information) and finds that 29 of them are listed as "eclectic" style. What is the 80% confidence interval for the proportion of homes that are "eclectic"?
Answer:
80% confidence interval for the proportion of homes that are "eclectic" is [0.59 , 0.78].
Step-by-step explanation:
We are given that James takes a random sample of 42 homes form the Austin MLS (that's where Realtors go for information) and finds that 29 of them are listed as "eclectic" style.
Firstly, the pivotal quantity for 80% confidence interval for the population proportion is given by;
P.Q. = [tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] ~ N(0,1)
where, [tex]\hat p[/tex] = sample proportion of homes that are "eclectic" = [tex]\frac{29}{42}[/tex] = 0.69
n = sample of homes = 42
[tex]\mu[/tex] = population proportion of homes that are "eclectic"
Here for constructing 80% confidence interval we have used One-sample z proportion statistics.
So, 80% confidence interval for the population proportion, p is ;
P(-1.282 < N(0,1) < 1.282) = 0.80 {As the critical value of z at 10% level
of significance are -1.282 & 1.282}
P(-1.282 < [tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] < 1.282) = 0.80
P( [tex]-1.282 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] < [tex]{\hat p-p}[/tex] < [tex]1.282 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] ) = 0.80
P( [tex]\hat p-1.282 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] < p < [tex]\hat p+1.282 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex] ) = 0.80
80% confidence interval for p = [ [tex]\hat p-1.282 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex],[tex]\hat p+1.282 \times {\sqrt{\frac{\hat p(1-\hat p)}{n} } }[/tex]]
= [ [tex]0.69-1.282 \times {\sqrt{\frac{0.69(1-0.69)}{42} } }[/tex] , [tex]0.69+1.282 \times {\sqrt{\frac{0.69(1-0.69)}{42} } }[/tex] ]
= [0.59 , 0.78]
Therefore, 80% confidence interval for the proportion of homes that are "eclectic" is [0.59 , 0.78].
1. Which student correctly simplified the expression 5.2 + 3.6x – 8 + x?
To simplify the expression 5.2 + 3.6x - 8 + x, combine like terms to get -2.8 + 4.6x, which is the final simplified expression.
Explanation:The student's question involves simplifying the expression 5.2 + 3.6x – 8 + x. To simplify the given algebraic expression, combine like terms. Like terms in this expression are the constant terms (5.2 and -8) and the variable terms (3.6x and x).
First, add the constant terms together:
5.2 - 8 = -2.8
Then, combine the variable terms:
3.6x + x = (3.6 + 1)x = 4.6x
Now, put the constants and variable terms together to get the simplified expression:
-2.8 + 4.6x
To check if the simplified expression is reasonable, ensure that all like terms have been correctly combined. There is no further simplification possible, so this is the final answer.

Answer:
1/10
Step-by-step explanation:
So first we need to find the probability of the cards, there is 5 cards and one card needs to be chosen, so the probability is 1/5
Then we need to find the probability of the dice, there is 3 even numbers in 1,2,3,4,5,and 6, so the probablity is 3/6 which is also equal to 1/2
Finaly we need to multiply 1/5 with 1/2, which is 1/10

A box has the shape of a rectangular prism with height 32 cm. If the
height is increased by 0.9 cm, by how much does the surface area of the
box increase?
32 cm
Use pencil and paper. Show your work. Then show a second way to
19 cm
7.2 cm
Answer:
47.16 Square centimeters
Step-by-step explanation:
Width=7.2cm
Length =19cm
Height =32cm
Surface Area=2(LW+LH+WH)
=2(19*7.2+19*32+7.2*32)
Surface Area [tex]=1950.4 cm^2[/tex]
When the height is increased by 0.9cm
Height =32.9cm
Surface Area=2(LW+LH+WH)
=2(19*7.2+19*32.9+7.2*32.9)
Surface Area [tex]=1997.56 cm^2[/tex]
Difference in Surface Area=1997.56-1950.4
=47.16 Square centimeters
An alternative way is to calculate the surface area dealing with the height only using the height difference,
Difference=2(LH+WH)
=2(19*0.9+7.2*0.9)
=47.16 Square centimeters

Hope this helps at all. :)
To solve for d in T = 7c - 2d, isolate the variable d by moving the term with d to the other side of the equation and simplifying.
Explanation:To solve for d in the equation T = 7c - 2d, we need to isolate the variable d. First, we'll start by moving the term with d to the other side of the equation.
Step 1: Add 2d to both sides of the equation.
T + 2d = 7c
Step 2: Now, we'll isolate the variable d by subtracting T from both sides of the equation.
2d = 7c - T
Step 3: Finally, divide both sides of the equation by 2 to solve for d.
d = (7c - T)/2

If 2 liters of sea water contain 70 grams of salt, how much salt is in 32 liters of sea water?
Answer:
1120 grams
Step-by-step explanation:
The amount of sea water is directly proportional to the amount of salt in the water.
Let the amount of sea water be W and the amount of salt be S.
This means that:
W α S
=> W = kS
where k = constant of proportionality
2 liters of sea water contain 70 grams of salt Therefore:
2 = k * 70
k = 2 / 70 = 1/35
Therefore, for 32 liters of sea water:
32 = 1/35 * S
S = 35 * 32
S = 1120 grams
There are 1120 grams of salt in 32 liters of water.
