Answer:
Marika's calculation is correct
Step-by-step explanation:
Lori has erroneously identified a common ratio of the geometion sequence
one has to divide subsequent term by the preceding term as was correctly by Marika. so Marika's calculation is correct.
hope it helps...
have a great day !!!

Answer:
2x^3 +7x^2+3x-2
Step-by-step explanation:
3x^3 +7x^2 -x
- ( x^3 -4x +2)
------------------------
The first step is to line up the variables by degree
3x^3 +7x^2 -x
- ( x^3 -4x +2)
----------------------------
Then distribute the minus sign
3x^3 +7x^2 -x
- x^3 +4x -2
----------------------------
2x^3 +7x^2+3x-2

=3x-14g According to the U.S. department of Agriculture (USDA), 48.9% of males aged 20 to 39 years consume the recommended daily requirement of calcium. After an aggressive "Got Milk" advertising campaign, the USDA conducts a survey of 35 randomly selected males aged 20 to 39 and finds that 21 of them consume the recommended daily allowance (RDA) of calcium. At the ????=0.05level of significance, is there evidence to conclude that the percentage of males aged 20 to 39 who consume the RDA of calcium has increased?
Answer:
We can conclude that there is no sufficient evidence to conclude that the percentage of males aged 20 to 39 who consume the RDA of calcium has increased
Step-by-step explanation:
H0 : p = 0.489
H1 : p > 0.489
Phat = x/ n ; x = 21 ; n = 35
Phat = x/ n = 21 / 35 = 0.6
Test statistic :
(Phat - P0) ÷ sqrt[P0(1 - P0) /n]
1 - P0 = 1 - 0.489 = 0.511
Phat - P0 = 0.6 - 0.489 = 0.111
Test statistic = 0.111 ÷ sqrt[(0.489 * 0.511) / 35]
Test statistic = 0.111 ÷ sqrt(0.0071394)
Test statistic = 0.111 ÷ 0.0844949
Test statistic = 1.314
Pvalue from Tstatistic :
Pvalue = P(Z < 1.314) = 0.90558
α = 0.05
Pvalue > α ; Hence, we fail to reject the Null
We can conclude that there is no sufficient evidence to conclude that the percentage of males aged 20 to 39 who consume the RDA of calcium has increased

These state exam questions are checking that you know certain things about linear equations and inequalities, and how to solve and graph them. It is also checking that you now the meanings of certain math terms and can translate those meanings to relationships between numbers.
__
1. The "slope-intercept form" of a linear equation is ...
y = mx + b . . . . . . where m is the slope and b is the y-intercept
Note that the left side is "y =", eliminating the last two answer choices.
The problem tells you the slope is m = 2, and the y-intercept is b = 5. Then the equation is ...
y = 2x + 5 . . . . matches A
__
2. The picture is fuzzy, but we think it says y ≥ 1. The little bar in the comparison symbol means "or equal to", so you're looking for a graph that shows numbers greater than or equal to 1. The "or equal to" means the end dot on the graph will not be an open circle, but will be a solid dot. The "greater than" means the shaded part of the line is to the right of that dot.
graph C is the appropriate representation
__
3. The picture is fuzzy, but we think it says 126 < -7x. For this sort of inequality, you are expected to know that multiplying or dividing by a negative number will reverse the inequality symbol.
126 < -7x . . . . given
126/-7 > x . . . . divide both sides by the coefficient of x, -7
-18 > x . . . . . matches D
__
4. This is a vocabulary question. Angles are "complementary" when their sum is 90°. The sums of the given angle pairs are ...
A: 90° . . . . the correct answer choice
B: 100°
C: 180°
D: 185°

At Pizza Pi, 40% of the pizzas made last week had extra cheese. If 8 pizzas had extra cheese, how many pizzas in all were made last week?
Answer:
20 pizzas.
Step-by-step explanation:
40% = 8
1% = 8 ÷ 40 = 0.2
100% = 0.2 x 100 = 20

she finds a hotel that charges 84 euros per night, she thinks this will be about £100. Is she right?
Answer:
she is wrong
Step-by-step explanation:
Using the conversion rate
1 Euro equals =0.87 Pound sterling
84 euros = x
Cross multiply
1 * x = 0.87 * 84
x = 0.87 * 84
x = 73.08 pounds
Since 84 euros is not up to 100pounds,. Hence she is wrong
ZA and B are vertical angles. If m A = (5x + 6) and m B = (6.2 – 25)°, then find the value of x.
Answer:
The value of x is 25.83.
Step-by-step explanation:
Vertical angles:
If two angles are vertical, they have the same measure.
In this question:
Angle A has measure 5x + 6
Angle B has measure 6.2x - 25
Since they are vertical:
[tex]A = B[/tex]
[tex]5x + 6 = 6.2x - 25[/tex]
[tex]1.2x = 31[/tex]
[tex]x = \frac{31}{1.2}[/tex]
[tex]x = 25.83[/tex]
The value of x is 25.83.

Answer:
x = 7
y = 16
upper 2 sides = 12
lower 2 sides = 19
Step-by-step explanation:
2x + 5 = x + 12
combine like terms:
x = 7
y - 4 = x + 5
y - 4 = 7 + 5
combine like terms:
y = 16
Upper sides = 7 + 5 = 12
Lower sides = 7 + 12 = 19
Consider the function f(x) = x3 + 34 over the interval [–3, 4]. According to the extreme value theorem, the function has a minimum value of
and a maximum value of
.
The answer for this question is:
7, 98
The minimum value of the function is 7 and the maximum value of the function will be 98.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
The function is given below.
f(x) = x³ + 34
The function is defined for the interval of [–3, 4].
The minimum value of the function at x = –3 will be
f(–3) = (–3)³ + 34
f(–3) = –27 + 34
f(–3) = 7
The maximum value of the function at x = 4 will be
f(4) = (4)³ + 34
f(4) = 64 + 34
f(4) = 98
Thus, the minimum value of the function is 7 and the maximum value of the function will be 98.
The graph is given below.
