An integer is 15 more than 2 times another. If the product of the two integers is -25, then whats the integers.
Answer:
15 + 2 x X = -25
Step-by-step explanation:
subtract 15 from both sides
2 x X = -40
divide two from both sides
X = -20
10÷ 5/8 I need help to answer this
Answer:
16
Step-by-step explanation:
10÷5/8=16
Answer:
16
Step-by-step explanation:
To solve problems where a fraction is being divided, we use a reciprocal of the fraction, which means that you flip the fraction upside down and multiply by the other number. So for this problem, the opposite of 5/8 is 8/5, so we need to multiply that by 10.
10*8/5
80/5
16

Step-by-step explanation:
A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore. Suppose that a storm is in progress with a severe storm class rating. Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down. The next 10 waves have an average wave height is 16 feet with a SD of .6 ft. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis
Answer:
The alternate hypothesis is:
[tex]H_{a} < 16[/tex]
Step-by-step explanation:
There are two types of hypothesis. The null hypothesis and the alternate hypothesis. The null hypothesis is that the mean found is equal to the expected value. The alternate hypothesis is a question about this expected value(different, more, less)
A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore.
This means that the null hypothesis is [tex]H_{0} = 16.4[/tex]
Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis
Dying down means lower average peak, that is, lower than the average of 16.4. This means that the alternate hypothesis is:
[tex]H_{a} < 16[/tex]
what is the answer of
reciprocal of 1/7
Answer:
7/1
Step-by-step explanation:
A reciprocal means you flip the numerator and the denominator (the top number and the bottom number) so In this case the reciprocal for 1/7 s 7/1.

heyy pls help ty lol
Answer: 5/12
Step-by-step explanation:
Answer:
5/12
Step-by-step explanation:
We are going to change both number so they have the same denominators.
1/4x3/3= 3/12
2/3x4/4=8/12
Once we changed the number we are going to subtract the numbers.
8/12-3/12=5/12
We can't simplify 5/12 so the answer is 5/12.
Nutritionists measured the sugar content (in grams) for 32 drinks at Jake's Java
coffee shop. The drinks had a mean sugar content of 18g and a standard
deviation of 5g, and the distribution was roughly symmetric.
Question 1: Grande Mocha Cappuccino at Jake's Java contains 14 g of sugar.
Calculate the standardized score (z-score) for the Grande Mocha Cappuccino.
Answer:
[tex]z = -0.8[/tex]
Step-by-step explanation:
Given
[tex]n = 32[/tex] --- samples
[tex]\mu = 18g[/tex] --- mean
[tex]\sigma =5g[/tex] --- standard deviation
[tex]x = 14g[/tex] --- observed value
Required
Find the standardized score
This is calculated as:
[tex]z = \frac{x - \mu}{\sigma}[/tex]
So:
[tex]z = \frac{14g -18g}{5g}[/tex]
[tex]z = \frac{-4g}{5g}[/tex]
[tex]z = \frac{-4}{5}[/tex]
[tex]z = -0.8[/tex]
The standardized score is -0.8
solve following values for x and y
Answer:
value of x
(8x+7)°=(9x-4)°
vertically opposite angles are equal
8x°-9x°=-4°-7°
-x°=-11°
divide both sides by -1° don't counsel negative
x=11
value of Y
5y°=(7y-34)°
vertically opposite angles are equal
5y°-7y°=34°
-2y°=34°
divide both sides by-2° don't counsel negative
y=17
6x^2 - 37x + 13 = 6

Answer:
9
Step-by-step explanation:
So the little arrows on the lines means they are equal to each other so if you look, A to D and B to C have only one arrow meaning those two lines are the same lines
and A to B and D to C have two arrows meaning those two lines are the same
so that means if A to B is 9 and it's equal to the line D to C, then D to C is also 9
Hopefully this wasn't too confusing
Answer:
mCD = 9
Step-by-step explanation:
Because this polygon has opposite parallel sides, meaning each side across from each other are parallel, we know that this is a parallelogram. So:
AB ║ DC
BC ║ AD
Because this is a parallelogram, we know that, from the properties parallelograms, opposite sides of a parallelogram are congruent. This means that AB ≅ DC.
This also means that because AB = 9 and AB = DC, DC = 9.
Here's a mini two-column proof:
Statements → Reasons
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
mAB = 9 → Given
AB ║ DC, BC ║ AD → Given
ABCD is a parallelogram → Definition of a Parallelogram
AB ≅ DC → Opposite sides of a parallelogram are congruent.
mAB = mDC → Definition of Congruent Segments
9 = mDC → Substitution Property of Equality
mCD = mDC → Reflexive Property of Equality
mCD = 9 → Substitution Property of Equality

Answer:
x = 7√3, y = 14x = √3, y = 3Step-by-step explanation:
Use the property of 30-60-90 degree right triangles
They have the ratio of sides from smallest to greatest: 1: √3 : 2
The top triangle
y = 2*7 = 14x = 7√3The bottom triangle
Acute angles n and 2n makes them 30° and 60°
x = 1/2*2√3 = √3y = √3*√3 = 3Answer:
x = 1/2*2√3 = √3
y = √3*√3 = 3

What is the geometric mean of 32 and 45? Round your answer to the nearest tenths place.
Can we conclude that two similar figures can also be congruent figures? Explain.
Answer:
In similar figures, the angles are congruent, even if the sides are not. Notice that one angle in each pair of figures corresponds to an angle in the other figure. They have the same shape but not the same size
Louis has a bag of 2510 shells each pen shell is 18 cm long what is the combine length of the pen shells in meters

Answer:
A
Step-by-step explanation:
a number increased by 9 is 13
Answer:
4
Step-by-step explanation:
To find the number you have to reverse the equation
Let us call the number "x"
x + 9 = 13
So to find x we flip the equation
13 - 9 = x
Solve it
4 = x
So the missing number is 4

Answer:
part A: D Marina
part B: A Anna
Step-by-step explanation:
If you're not that familiar with these fractions and their equivalents, you can always compare them using their least common denominator: 24.
Joseph: 1/3 = 8/24
Anna: 1/6 = 4/24
Elvin: 3/12 = 6/24
Theo: 1/4 = 6/24
Marina: 5/8 = 15/24
Then the ordering from least-to-greatest is ...
Anna, {Elvin, Theo}, Joseph, Marina
Part A
Marina reached the greatest fraction of the goal.
Part B
Anna reached the least fraction of the goal.
