The 7th term of the given geometric sequence is equal to: A. 448.
Given the following sequence:
7, -14, 28, -56....What is a geometric sequence?A geometric sequence can be defined as a series of real and natural numbers that are generally calculated by multiplying the next number by the same number each time.
Mathematically, a geometric sequence is given by the expression:
[tex]a_n =a_1r^{n-1}[/tex]
Where:
r is the common ratio.[tex]a_1[/tex] is the first term of a geometric sequence.Substituting the given parameters into the formula, we have;
[tex]a_{7} =7 \times -2^{7-1}\\\\a_{7} =7 \times -2^{6}\\\\a_{7} =7 \times 64[/tex]
7th term = 448.

Has he enough money to buy two denim shirts on
Special Offer Day? You must show all your working.
Special Offer Day

off normal prices
Answers
Answer:
Yes, Billy will have enough money to buy two denim shirts.
Step-by-step explanation:
£9.60 × (1/3)
= £3.20
On the special offer day, a denim shirt will cost £3.20.
£3.20×2 = £6.40
Two shirts will cost £6.40
Billy has £13, which will be enough for him to buy two shirts and will have a remaining balance of £6.60
During the 2015 baseball season, the Detroit Tigers' Miguel Cabrera hit for the elusive Triple Crown by having the highest batting average, most home runs, and most runs batted in. Most baseball players average four at-bats per game. Using Cabrera's batting average of 0.338, the probability that he would get no hits in one game would be 0.192, one hit would be 0.392, two hits would be 0.300, and three hits would be 0.102. Using the probability distribution table given, what is the probability that Miguel Cabrera gets a hit in all four at-bats?
x 0 1 2 3 4
p(x) 0.192 0.392 0.300 0.102
Answers
Answer:
The probability that Miguel Cabrera gets a hit in all four at-bats is 0.014
Step-by-step explanation:
Given
[tex]\begin{array}{cccccc}x & {0} & {1} & {2} & {3} & {4} \ \\ {P(x)} & {0.192} & {0.392} & {0.300} & {0.102} & { } \ \end{array}[/tex]
Required
P(x = 4)
To do this, we use the following formula:
[tex]\sum\limit^n_{x=i} P(x) = 1[/tex]
In this case, the above formula can be interpreted as:
[tex]P(x = 0) + P(x = 1) + P(x = 2) + P(x =3) + P(x = 4) = 1[/tex]
This gives:
[tex]0.192 + 0.392 + 0.300 +0.102 + P(x = 4) = 1[/tex]
[tex]0.986 + P(x = 4) = 1[/tex]
Collect like terms
[tex]P(x = 4) = -0.986 +1[/tex]
[tex]P(x = 4) = 0.014[/tex]

The solution to these question can be defined as follows:
Step-by-step explanation:
[tex]H_0: \mu = 33 \ versus\\\\ H_a: \mu > 33\\\\\bar{X} = 33.11\\\\S = 4.7468\\\\n = 47\\\\df = n - 1 = 46\\\\\alpha = 0.05\\\\[/tex]
Testing statistic:
[tex]t = \frac{(\bar{X} - \mu)}{[\frac{S}{\sqrt{(n)}}]}[/tex]
[tex]= \frac{(33.11 – 33)}{\frac{4.7468}{\sqrt{47}}}\\\\= \frac{0.11}{0.6924}\\\\= 0.1589\\\\P-value = 0.4372\\\\P-value > \alpha = 0.05[/tex]
Therefore the null hypothesis we do not deny, it is not clear enough so that the median age once British men get engaged is higher than in 2013.

What is multiplication?The mathematical operation of multiplication is arithmetic. Additionally, it involves repeating the same forms of statements.
Example: 2 + 3 signifies that 2 is multiplied by 3 or that 3 is multiplied by 2 times.
A carpenter bought 850 nails.
Each nail has a mass of 5.2 x 10-3 kg.
To find the total mass:
Use multiplication operation,
850 x 5.2 x 10⁻³
= 4420 x 10⁻³
= 442 x 10⁻²

From the given figure,
Measure of an angle = 34°
Adjacent side of the given angle = 40m
We have to find the length of the opposite side.
By applying tangent rule in the given right triangle,
tan(34°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
Opposite side = Adjacent side × tan(34°)
= 40 × 0.6745

≈ 27 m
Therefore, height of the flagpole is approximately 27 m.

Sofia is purchasing a home for a list price of $245,000. She has a dow payment of $25,000 and takes out a 20 year mortgage for the remainder at 5 annual interest. Determine her monthly payments.

Answers
Answer:
Sofia's monthly payments will be $ 1,222.22.
Step-by-step explanation:
Given that Sofia is purchasing a home for a list price of $ 245,000, and she has a down payment of $ 25,000 and takes out a 20 year mortgage for the remainder at 5 annual interest, to determine her monthly payments the following calculation must be performed:
((245,000 - 25,000) x 0.05 x 20 + (245,000 - 25,000)) / 30 x 12 = X
(220,000 x 0.05 x 20 + 220,000) / 360 = X
(11,000 x 20 + 220,000) / 360 = X
(220,000 + 220,000) / 360 = X
440,000 / 360 = X
1,222.22 = X
Therefore, Sofia's monthly payments will be $ 1,222.22.

It is given that:
A sphere with a diameter of 9 units fits exactly in the clear glass cube.
Diameter = 9 units
The radius r = 9/2 units
The volume of the sphere:
[tex]\rm V = \dfrac{4}{3} \pi (9/2)^3[/tex]
[tex]\rm V = \dfrac{4}{3} \pi (4.5)^3[/tex]
The volume of cube = a³
a is the side length
The volume of the cube = (9)³
The volume, in cubic units, of empty space in the cube:
