Answer:
d - 11*16
Step-by-step explanation:
Algebraic Expressions
We use algebraic expressions to model real-world situations and we must pay close attention to the writing of the problem to do it properly and accurately.
Let's build the expression in small steps:
11 times the quantity 16 = 11*16
That amount less than a number d. It suggests a subtraction:
d - 11*16
what does x equal in the equation [tex]\frac{3}{5}x- \frac{1}{4}x=7\\[/tex]
Answer:
[tex] x = 20 [/tex]
Step-by-step explanation:
[tex] \frac{3}{5}x - \frac{1}{4}x = 7 [/tex]
The LCD is 20, so multiply both sides of the equation by 20.
[tex] 20(\frac{3}{5}x - \frac{1}{4}x) = 20 \times 7 [/tex]
[tex] 4 \times 3x - 5 \times x = 140 [/tex]
[tex] 12x - 5x = 140 [/tex]
[tex] 7x = 140 [/tex]
[tex] x = 20 [/tex]

Eight more than the quotient of a number and 6 equals 3.
Hey there!
First of all, the quotient of a number and 6 means you divide that number by 6.
Let the number be x.
Then, eight more means you add 8:
8+(6÷x)=3
That's the answer.
Hope everything is clear.
Let me know if you have any questions!

At book fair, the ratio of adults to children is 7 : 3
The ratio of girls to boys at the book fair is 4 : 1
What percentage of the people at the book fair are boys?
The percentage of the boys at the book fair is 6%
What is a percentage?Percentages are used in mathematics as a decimal ratio expressed in a fraction of 100. It is represented with a symbol known as %.
At a book fair, the ratio of adults to children are:
7 : 3
The total number of people at the book fair = 7 + 3 = 10
The percentage of adults are:
[tex]\mathbf{=\dfrac{7}{10}\times 100\%}[/tex]
= 70% are adults
The percentage of children are:
[tex]\mathbf{=\dfrac{3}{10}\times 100\%}[/tex]
= 30% are children
However, if from the children, 4 are girls and 1 is a boy.
The total number of children at the fair = 4 + 1 = 5
The percentage of girls are:
[tex]\mathbf{=\dfrac{4}{5} \times 30\%}[/tex]
= 24%
The percentage of boys at the book fair is:
[tex]\mathbf{=\dfrac{1}{5} \times 30\%}[/tex]
= 6%

Which equation for g(x) represents the transformation of f(x) given that f(x) = x^2
g(x) = f(x) shifted up 2 units
i have more translation of quadratics questions i need some help on so if you’re willing let me know
Answer:
g(x) = x² + 2
Step-by-step explanation:
If we want to shift a function down, we subtract the number we are asked to move outside the function's argument:
⇒ To shift f(x) b units down → f(x) - b
Similarly, in function notation, if we want to shift a function up, we add the number we are asked to move outside the function's argument:
⇒ To shift f(x) b units up → f(x) + b
Given function f(x) = x²
Shift 2 units up ⇒ x² + 2
Therefore, g(x) = x² + 2

What is the slope of the equation y= 5/4 times -7/4
Answer:
5/4
Step-by-step explanation:
If the equation is
[tex] y = \dfrac{5}{4}x - \dfrac{7}{4} [/tex]
then the slope is the number multiplying x, so
slope = 5/4.
Answer:
5/4.
The x is a variable, not a multiplication sign.
The equation is
y=mx+b
the slope is the m.
(X+1)²+(x+1)(5x-3) factoriser
Answer:
Step-by-step explanation:
(x +1)² + (x +1)(5x - 3) = (x +1)(x+1) + (x +1)(5x - 3)
(x +10 is the common term. SO, we can take out (x+1)
=(x +1) [ x + 1 + 5x - 3]
=(x + 1) (x + 5x + 1 - 3) {Combine like terms}
= (x +1)(6x -2)

below
Step-by-step explanation:
Question 1:
In a function, every output value corresponds to exactly one input value.
The words that should be switched around are "output" and "input". This is because every input should have have only ONE output.
Question 2:
The following graph fails the vertical line test and is not a function. (YES)
Using the vertical line test to test whether the vertical line passes through the graphed function more then once. If it does, its not a function. If it doesn't, it is a function. Sadly, the vertical lines pass the point on two separate occasions which makes it not a function.
The vertical line shows gives the points (4, 2) and (4, -2).

Due to festive season, the price of air tickets increased by 15%. If the price of one ticket was $575 during the festive season, what was its price before the festive season?
answer fast
The price before the festive season is $488.75
Data;
percentage increase = 15%ticket price = $575The Price before the festive seasonTo calculate the price before the festive season, we simply need to subtract 15% from $575.
[tex]\frac{15}{100} = \frac{x}{575} \\x = 86.25[/tex]
The increase in the ticket is $86.25., Let's calculate the price before the festive season.

A researcher wants to determine whether or not a five-week crash diet is effective over a long period of time. A random sample of 15 dieters is selected Each person's weight is recorded before starting the diet and one year after it is concluded. Based on the data shown at right (weight in pounds), Can we conclude that the diet has a long-term effect, that is, that dieters manage to not regain the weight they lose? Include appropriate statistical evidence to justify your answer.
BEFORE
158 185 176 172 164 234 258 200 228 246 198 221 236 255 231
AFTER
163 182 188 150 161 220 235 191 228 237 209 220 222 268 234
Using the t-distribution, as we have the standard deviation for the sample, it is found that it cannot be concluded that the diet has a long-term effect.
What are the hypotheses tested?At the null hypotheses, it is tested if there is no difference in the weights, that is:
[tex]H_0: \mu_A - \mu_B = 0[/tex]
At the alternative hypotheses, it is tested if the weights decrease, that is:
[tex]H_1: \mu_A - \mu_B < 0[/tex]
What is the mean and the standard deviation of the distribution of the difference?Using a calculator, for each sample, we have that:
[tex]\mu_B = 210.8, s_B = 33.85, sE_B = \frac{33.85}{\sqrt{15}} = 8.74[/tex]
[tex]\mu_A = 207.2, s_A = 33.47, sE_A = \frac{33.47}{\sqrt{15}} = 8.64[/tex]
Hence, for the distribution of differences, we have that:
[tex]\overline{x} = \mu_A - \mu_B = 207.2 - 210.8 = -3.6[/tex]
[tex]s = \sqrt{sE_B^2 + sE_A^2} = \sqrt{8.74^2 + 8.64^2} = 12.3[/tex]
What is the test statistic?It is given by:
[tex]t = \frac{\overline{x} - \mu}{s}[/tex]
In which [tex]\mu = 0[/tex] is the value tested at the null hypothesis.
Then:
[tex]t = \frac{\overline{x} - \mu}{s}[/tex]
[tex]t = \frac{-3.6 - 0}{12.3}[/tex]
[tex]t = -0.29[/tex]
What is the decision?Considering a left-tailed test, as we are testing if the mean is less than a value, with a standard significance level of 0.05 and 15 + 15 - 2 = 28 df, the critical value is of [tex]t^{\ast} = -1.7[/tex].
Since the test statistic is greater than the critical value for the left tailed test, it cannot be concluded that the diet has a long-term effect, as the null hypothesis is not rejected.
