Answer:

k= 0.8936

P = 53198890

Step-by-step explanation:

In 2008

t = 8
P= 7000

As per equation, P = 5.5e^kt

7000 = 5.5e^(8k)
e^(8k) = 7000/5.5
e^(8k) = 1272.7272
ln e^8k = ln 1272.7272
8k = 7.14891
k= 7.14891/8
k= 0.8936

In 2018, t= 18, k= 0.8936

P = 5.5e^(18*0.8936)
P = 53198890

Solve −3x2 − 4x − 4 = 0

kkurt [141]

This is a quadratic formula with a general form of a²x + bx + c = 0. For quadratic equations, we can solve for its two roots using the quadratic formula shown in the attached picture.

a = -3
b = -4
c = -4

x = [-(-4) + √(-4)² - 4(-3)(-4)]/2(-3) = 2 + √-32/2
x = [-(-4) - √(-4)² - 4(-3)(-4)]/2(-3) = 2 - √-32/2

If 141 people attend a concert and tickets for adults cost $3.5 while tickets for children cost $2.5 and total receipts for the

Arturiano [62]

Answer: There are 69 adults and 72 children went to the concert.

Step-by-step explanation:

Let x be the number of adults, and y be the number of children.

x + y = 141

3.5x + 2.5y = 421.5

x + y =141

x = 141 - y

3.5(141 - y) + 2.5y = 421.5

493.5 - 3.5y + 2.5y = 421.5

493.5 - y = 421.5

-y = -72

y = 72

x + y = 141

x + 72 = 141

x = 69

HELP ASAP FOR BRAINLIEST: The mean score for a standardized test is 1700 points. The results are normally distributed with a sta

WITCHER [35]

Answer:

Step-by-step explanation:

Since the results for the standardized test are normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = test reults

µ = mean score

σ = standard deviation

From the information given,

µ = 1700 points

σ = 75 points

We want to the probability that a student will score more than 1700 points. This is expressed as

P(x > 1700) = 1 - P(x ≤ 1700)

For x = 1700,

z = (1700 - 1700)/75 = 0/75 = 0

Looking at the normal distribution table, the probability corresponding to the z score is 0.5

P(x > 1700) = 1 - 0.5 = 0.5

Find the value of 11 +22+33 + ... + 1100.

ella [17]

Answer:

sum of terms: 55550

Explanation:

$\sf S_n = \dfrac{n}{2} (u_{start}+u_{end}})$

Here the number of terms:

1100 ÷ 11 = 100

Using the Formula:

$\sf \dfrac{100}{2} (11+1100)$

$\sf 55550$
