Answer:
12
Step-by-step explanation:
[tex]y = - x {}^{2} + bx + 10 \\ y = - (x {}^{2} - bx - 10) \\ y = -( (x - \frac{b}{2} ) {}^{2} - \frac{b {}^{2} }{4} - 10) \\ y = - (x - \frac{b}{2} ) {}^{2} + 10 + \frac{b {}^{2} }{4} \\ \\ therefore \: \frac{b}{2} = 6 \\ b = 12[/tex]

If the news gives a prediction of a 75% chance of rain tomorrow, what is the probability that it will not rain tomorrow?
Plz ASAP with explanation please
Answer:
25%
Step-by-step explanation:
There is always a total of 100% probability, no matter how many options there are. In this case, it either rains or it doesn't. If there is a 75% chance of rain, the chance of no rain must combine with 75% to make 100%. 100% - 75% = 25%.

In the triangle below, what is the length of the side opposite the 30° angle?
Answer:
Step-by-step explanation:
take 30 degree as reference angle
using sin rule
sin 30=opposite /hypotenuse
1/2=opposite/2[tex]\sqrt{3[/tex]
opposite=2[tex]\sqrt{3[/tex] /2
opposite=[tex]\sqrt{3[/tex]
Answer:
√3
Step-by-step explanation:
let length of side opposite 30⁰ be x
sin 30= x/ (2√3)
½=x/(2√3)
cross multiply
2x=2√3
x=√3
length opposite 30⁰= √3

Step-by-step explanation:
Area of a triangle formula:
A = 0.5bh
Given:
b = 4
h = 2
Work:
A = 0.5bh
A = 0.5(4)(2)
A = 2(2)
A = 4

A density curve for all the possible weights between 0 pounds and 10 pounds is in the shape of a rectangle. What is the height of the rectangle in this density curve? O A. 0.01 OB. 0.001 O c. 0.1 O D. 0.0001 SUBMIT
Answer:
0.1
Step-by-step explanation:
For a density curve, total area = 1
Probability lies in between 0 and 1
The Area of rectangle :
Area = Length * width
Length = 0 - 10 = 10
Area = 1
Hence,
Area = Length * width
1 = 10 * w
1 = 10w
w = 1 /10
w = 0.1
Grandma Gertrude’s Chocolates, a family owned business, has an opportunity to supply its product for distribution through a large coffee house chain. However, the coffee house chain has certain specifications regarding cacao content as it wishes to advertise the health benefits (antioxidants) of the chocolate products it sells. In order to determine the mean % cacao in its dark chocolate products, quality inspectors sample 30 pieces. They find a sample mean of 4% with a standard deviation of 2%. What is the margin of error at 90% confidence?
a. 1.49%
b. 1.24%
c. 0.62%
d. 0.75%
e. 1.36%
Answer:
c. 0.62%
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 30 - 1 = 29
90% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 29degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 1.6991
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}}[/tex]
Sample of 30, standard deviation of 2%.
Then
[tex]M = T\frac{s}{\sqrt{n}} = 1.6991\frac{2}{\sqrt{30}} = 0.62[/tex]
0.62%, so option c.

The graph equation
From the graph, we have:
[tex](x_1,y_1) = (0,0)[/tex]
[tex](x_2,y_2) = (1,1)[/tex]
The slope of the graph is:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{1-0}{1-0}[/tex]
[tex]m = \frac{1}{1}[/tex]
[tex]m =1[/tex]
So, the graph equation is:
[tex]y = m(x - x_1) + y_1[/tex]
[tex]y = 1 * (x - 0) + 0[/tex]
[tex]y = 1 * x[/tex]
[tex]y = x[/tex]
In standard form, we have:
[tex]x - y = 0[/tex]

A study on the latest fad diet claimed that the amounts of weight lost by all people on this diet had a mean of 23.2 pounds and a standard deviation of 6.6 pounds. Step 2 of 2 : If a sampling distribution is created using samples of the amounts of weight lost by 65 people on this diet, what would be the standard deviation of the sampling distribution of sample means
Answer:
The standard deviation of the sampling distribution of sample means would be 0.8186.
Step-by-step explanation:
We are given that
Mean of population=23.2 pounds
Standard deviation of population=6.6 pounds
n=65
We have to find the standard deviation of the sampling distribution of sample means.
We know that standard deviation of the sampling distribution of sample means
=[tex]\frac{\sigma}{\sqrt{n}}[/tex]
Using the formula
The standard deviation of the sampling distribution of sample means
=[tex]\frac{6.6}{\sqrt{65}}[/tex]
[tex]=0.8186[/tex]
Hence, the standard deviation of the sampling distribution of sample means would be 0.8186.

Mia, an accountant, observes that her company purchased softball bats at a cost of $14 and
is currently selling them at a price of $21. What percentage is the mark-up?
Write your answer using a percent sign (%).
5%
(Markup percent/100) × Cost price = Selling price - cost price
=> (Markup percent/100) × $14 = $21 - $14
=> (Markup percent/100) × $14 = $7
=> (Markup percent/100) = $7 / $14
=>
Answer:
5% is the markup

What does Y=???? Plz help me been stuck on this
9514 1404 393
Answer:
y = 8
Step-by-step explanation:
It can be useful to write down the values of corresponding parts of the figures. This can help you see the ratio between corresponding measures. Here, we're concerned with sides.
AB = ?, FE= 6
BC = 10, EC = 5 . . . . . a ratio of 2:1
CD = ?, CG = ?
DA = y, GF = 4
So, the proportionality of the sides in these similar figures means ...
y/4 = 10/5
y = 4×10/5
y = 8 . . . . multiply by 4
