Answer:
1. d(4)(4) = 16d
Step-by-step explanation:
let d be the distance
Number of non rainy days in week is (5-1) =4
Number of weeks = 4
in a week a student travels 4d
in 4 weeks a student travels 4×4×d = 4(4)(d)= 16d
Kim's softball team was playing in the championship game. When there were 444 innings left, the team was losing by a score of 171717 to 666 points. In the last 444 innings, her team scored the same number of points per inning, and the other team did not score any more points. Kim's team won with the most points.
Write an inequality to determine the number of points per inning, ppp, Kim's team could have scored.
Answer:
Hello and welcome to Brainly! Thank you for posting your first question! I hope you enjoy your time here on Brainly!
The awnser to your question is. The required inequality is 6+4p>17
Step-by-step explanation:
Let p represent the number of runs per inning.
It is given that the team scores the same number of runs per inning and the other team did not score any more points. So, the total score of other team after last four inning is 17.
Kim's team total score in last four inning is 4p. So, the total score of Kim's team after last four inning is
Kim's team win if the total score of other team after last four inning is less than the Kim's team.

Solve: log (7t + 2) = 2
t =
Answer:
t = 14
Step-by-step explanation:
log (7t + 2) = 2
Raise each side to the power of 10
10 ^log (7t + 2) =10^ 2
7t+2 = 100
Subtract 2 from each side
7t+2-2 = 100-2
7t = 98
Divide each side by 7
7t/7 = 98/7
t = 14
Answer:
[tex]t=14[/tex]
Step-by-step explanation:
We begin with the equation: [tex]log(7t+2)=2[/tex]
The first thing we must do is remove the log. In this case, the base of this log is 10, which means that we must have each side of this equation have a base of 10.
This gives us
[tex]10^{log(7t+2)} =10^2[/tex]
The base 10 and the log will cancel out to give us
[tex]7t+2=100[/tex]
Then we can solve for t
[tex]7t+2=100\\\\7t=98\\\\t=\frac{98}{7} \\\\t=14[/tex]

Answer:
C /2pi = r
Step-by-step explanation:

We want to solve for r
Divide each side by 2 pi
C / 2pi = 2*pi*r / 2pi
C /2pi = r
A flashlight battery manufacturer makes a model of battery whose mean shelf life is three years and four months, with a standard deviation of three months. The distribution is approximately normal. One production run of batteries in the factory was 25,000 batteries. How many of those batteries can be expected to last between three years and one month and three years and seven months?
a. 21,025 batteries
b. 8,525 batteries
c. 17,050 batteries
See the attached picture.
The answer is c. 17,050 batteries
The number of expected batteries to last between 3 years and one month and 3 years and seven months is 17,050 batteries.
Option C is the correct answer.
What is z-score?A z-score also called a standard score is a measure of how many standard deviations a data point is away from the given mean of a distribution.
It measures the unusual or extreme a particular data point is compared to the rest of the distribution
We have,
First, we need to standardize the range of shelf life between three years and one month (3.08 years) and three years and seven months (3.58 years) using the formula:
z = (x - μ) / σ
where x is the shelf life in years, μ is the mean shelf life in years, and σ is the standard deviation in years.
Now,
For the lower bound:
z = (3.08 - 3.33) / 0.25
z = -1.00
For the upper bound:
z = (3.58 - 3.33) / 0.25
z = 1.00
Now,
We use a standard normal distribution table or calculator to find the area under the curve between z = -1.00 and z = 1.00, which represents the proportion of batteries that can be expected to last between three years and one month and three years and seven months.
This area is approximately 0.6826.
Finally,
We multiply this proportion by the total number of batteries in the production run to find the expected number of batteries that meet the criteria.
expected number = proportion x total number
expected number = 0.6826 * 25,000
expected number ≈ 17,065
Therefore,
The number of expected batteries is 17,050 batteries.

Find the volume of the cone below. Round your answer to the nearest tenth if necessary. Use 3.14 for π. * PLS show work
Answer:
-The volume of the cone is 100.5[tex]in^3[/tex] .
Step-by-step explanation:
To find the volume of cone, you need the formula:
[tex]V =\frac{1}{3} \pi r^2 h[/tex]
-Use the radius and the height for the formula:
[tex]V =\frac{1}{3} \pi 4^2 6[/tex]
-Then, you solve:
[tex]V =\frac{1}{3} \pi 4^2 6[/tex]
[tex]V = \frac{1}{3}\pi[/tex] × [tex]4^2[/tex] × [tex]6[/tex]
[tex]V = \frac{1}{3}\pi[/tex] × [tex]16[/tex] × [tex]6[/tex]
[tex]V = \frac{1}{3}\pi[/tex] × [tex]96[/tex]
[tex]V = \frac{96}{3} \pi[/tex]
[tex]V = 32\pi \approx 100.53[/tex]
-Round to the nearest tenth:
[tex]V \approx 100.5[/tex]
So, therefore, the volume of the cone is 100.5[tex]in^3[/tex] .
what is a hypotenuse
Answer:

Step-by-step explanation:
is the longest side in a triangle
Answer:
It is the longest side of a right triangle.
Step-by-step explanation:
A right triangle has two legs, then the (i call it a slope) hypotenuse connects the two from the top of one of leg to the end of the bottom leg.
you can calculate the hypotenuse via the Pythagorean theorem. which is A^2+B^2=C^2
Or: Leg 1^2+ Leg 2^2= Hypotenuse^2

What is the height of a pyramid (with a square base) whose side length is 12 cm and its slant
height is 10 cm?
a.) 22 cm
b.) 8 cm
c.) 2 cm
d.) None of these
We have been given that side length of pyramid the square base is 12 cm and its slant height is 10 cm. We are asked to find the height of the pyramid.
We will use slant height of a pyramid formula to solve our given problem.
[tex]s=\sqrt{h^2+\frac{1}{4}a^2}[/tex],where,
s = Slant height,
h = Height,
a = Each side of square base.
Upon substituting our given values in above formula, we will get:
[tex]10=\sqrt{h^2+\frac{1}{4}\cdot 12^2}[/tex]
[tex]10=\sqrt{h^2+\frac{1}{4}\cdot 144}[/tex]
[tex]10=\sqrt{h^2+36}[/tex]
Switch sides:
[tex]\sqrt{h^2+36}=10[/tex]
Let us square both sides:
[tex](\sqrt{h^2+36})^2=10^2[/tex]
[tex]h^2+36=100[/tex]
[tex]h^2+36-36=100-36[/tex]
[tex]h^2=64[/tex]
Now we will take positive square root of both sides.
[tex]\sqrt{h^2}=\sqrt{64}[/tex]
[tex]h=8[/tex]
Therefore, the height of the pyramid is 8 cm and option 'b' is the correct choice.

Answer:
Given:
Sample size, n = 6965
Sample proportion p' = [tex] \frac{1330}{6965} = 0.19 [/tex]
Let's claim that the return rate is less than 20%, ie, P = 0.2
Significance level = 0.01
The null and alternative hypotheses:
H0 : P = 0.2
H1 : P < 0.2
Option A is correct
_____________________________
For the test statistic, Z, let's use the formula:
[tex] Z = \frac{p'- P}{\sqrt{\frac{P(1-P)}{n}}} [/tex]
[tex] = \frac{0.19 - 0.2}{\sqrt{\frac{0.2(1 - 0.2)}{6965}}} = -1.887 [/tex]
Z = -1.887 ≈ -1.89
___________________________
The p-value.
This is a left tailed test.
Using z table,
P-value = P(Z ≤ -1.89) = 0.029
The pvalue is 0.029
Decision:
Because the pvalue, 0.029 is greater than level of significance, 0.01, we fail to reject null hypothesis, H0.
Conclusion:
There is not enough sufficient evidence to conclude that the return rate is less than 20%

Given f(x)=x^3+2x+k.
and x+1 is a factor of f(x), then what is the value of k?
Answer:
k = 3.
Step-by-step explanation:
By the Factor Theorem. if x+a is a factor of f(x) then f(-a) = 0.
Here we use f(-1):
f(-1) = (-1)^3 + 2(-1) + k = 0
-1 - 2 + k = 0
k = 3.

Answer:
Relax. The answer is 7t +5
Step-by-step explanation:
Circle the 2 variables (T)
Next re-write the equation and put the varbiles equation 6t+t.
Then you have 7-2 left, you then put it next to the new equation but make sure when you do that it looks like this 6t+t+7-2.
Last you solve and your answer should be 7t+5.
Note: If a variable is alone like the t then make sure you put a one next to it
